A flash flood is a flood that:
(a) is caused by heavy rain rather than from the flooding of a river
(b) occurs in urban areas
(c) occurs suddenly and unexpectedly and for a short duration
(d) is caused by the blocking of drains.
Answer: (c)
Flash floods are defined by the speed of flooding, not the source or location of flooding. While flash floods are often caused by heavy rainfall, they can also result from other events, such as drain blockages and bursts or the flooding of a river.

Monsoon is caused by: (CSS-2009)
(a) Seasonal reversal of winds
(b) Revolution of earth
(c) Movement of clouds
(d) Rise in temperature
(e) Rain forests
Answer: (a)
The monsoon, which is essentially the seasonal reversal in wind direction, causes most of the rainfall received in Pakistan and some other parts of the world. The primary cause of monsoons is the difference between annual temperature trends over land and sea. The apparent position of the Sun with reference to the Earth oscillates from the Tropic of Cancer to the Tropic of Capricorn. Thus the low pressure region created by solar heating also changes latitude. The northeast and southeast trade winds converge in this low pressure zone, which is also known as the Intertropical Convergence Zone or ITCZ. This low pressure regions sees continuous rise of moist wind from the sea surface to the upper layers of the atmosphere, where the cooling means the air can no longer hold so much moisture resulting in precipitation. The rainy seasons of East Asia, sub-Saharan Africa, Australia and the southern parts of North America coincide with the shift of ITCZ towards these regions.

A flood can vary in:
(a) size
(b) speed of water flow
(c) duration
(d) all of the above.
Answer: (d)
The size, duration and water flow speed of floods can vary. The volume, rate of rise and areal extent (i.e. the total area under flood waters) of flooding can also vary.

When a river’s water level reaches 10 meters, this means that:
(a) the water level is 10 meters above an arbitrary ‘zero’ level
(b) the water level is 10 meters above mean sea level
(c) the water level is 10 meters above mean sea level or an arbitrary ‘zero’ level
(d) it will flood.
Answer: (c)
River height is the level of water in a river as measured by a river gauging station and is expressed in meters above either the Australian Height Datum (i.e. mean sea level) or an alternative arbitrary ‘zero’ level, depending on the location.

The size of a flood is measured by:
(a) the rate of flow of water in a waterway or river
(b) the level of water in a waterway or river
(c) a river gauging station
(d) all of the above.
Answer: (d)
The size of a flood can be measured by the highest level that water in a waterway reaches, referred to as the ‘peak water level’ or ‘flood peak’. It can also be measured by the maximum water flow rate in a waterway, referred to as the ‘peak flow rate’ or ‘peak water flow’. Each of these variables can be measured using a river gauging station.

Which of the following is associated with a La Niña event?
(a) The Southern Oscillation Index (SOI) is strongly negative.
(b) The ocean surface off the coast of South America is warmer than usual.
(c) There is an increased chance of above average rainfall in eastern Australia.
(d) All of the above.
Answer: (c)
In a La Niña event, the equatorial ocean surface off the coast of South America is abnormally cool, and the SOI is strongly positive. Trade winds blow strongly across the warm Pacific, picking up plenty of moisture and increasing the likelihood of above average rainfall in eastern Australia.

Which of the following potentially affects the size of a flood?
(a) bridges and other structures in waterways
(b) the size and windiness of a river
(c) vegetation in and around a river
(d) all of the above.
Answer: (d)
Many factors can affect the size of a flood, including rainfall intensity, weather conditions prior to a rainfall event, tidal and storm surges, dams and other man-made and natural water storages, catchment size and shape, soil types in a catchment, vegetation in and around a waterway, the size and windiness of a waterway, levees, bridges and other structures in waterways and catchments, and urbanization.

(a) The movement of sun around the Milky Way
(b) The movement of the earth around the sun
(c) Relativistic Quantum
(d) None of these
Answer: (b)

The 2010 floods had cost the Pakistan’s economy around
(a) $17b
(b) $11b
(c) $10b
(d) $13b
Answer: (c)
It estimates that just a little less than 1pc of Pakistan’s GDP is exposed to river floods every year. It is ranked 16th by the WRI on the list of the top 20 countries with the highest GDP exposure to river floods.
The World Resources Institute (WRI) says Pakistan falls 5th on the list of top 15 countries that account for 80pc of the population exposed to river-flood risk worldwide.

In Pakistan, the most expensive natural disaster is:
(a) Drought
(b) Floods
(c) Bushfires
(d) Cyclones.
Answer: (b)
Pakistan faces a major financing challenge arising from natural catastrophes, with flooding causing an estimated annual economic impact of between three and four per cent of the federal budget,” adds the report. It estimates the annual economic impact of flooding at between $1.2bn and $1.8bn, or 0.5-0.8pc of GDP.

Which of the following is an environmental consequence of floods?
(a) dispersal of weed species
(b) erosion of soil
(c) release of pollutants into waterways
(d) all of the above.
Answer: (d)
Floods can have negative environmental consequences, such as soil erosion, release of pollutants and excess sediments and nutrients into waterways and the ocean, dispersal of weed species, and negative impacts on fish and other aquatic life. Floods can also have positive environmental consequences, such as recharging groundwater systems, filling wetlands, moving useful nutrients around the landscape, and triggering breeding events (for example, of water birds).

Which of the following is used to estimate which areas will be inundated during a flood, based on river height information?
(a) satellite and radar images
(b) flood maps / floodplain hydraulic models
(c) river gauging stations
(d) all of the above.
Answer: (b)
Floodplain hydraulic models and flood maps are used to estimate which areas will be inundated based on river height information. Satellite and radar images, rain gauges and river gauging stations are used to estimate river heights.

Which of the following statements is false?
(a) Weather forecasts for a small region are more accurate than those for a large region.
(b) Weather forecasts are more accurate in Melbourne than in Darwin.
(c) Forecasts of temperature are more accurate than forecasts of rainfall.
(d) All of the above.
Answer: (a)
The accuracy of weather forecasts varies depending on lead time, the size of the region of interest, the weather variable being forecast, and the latitude of the region. Generally, temperature forecasts are more accurate than rainfall forecasts; the mid-latitudes are easier to forecast than the tropics; and it is generally easier to forecast rainfall over a large area (for example, a large catchment) than local rainfall (for example, a reservoir).

Which of the following is true? Flood warnings:
(a) should not be released until the information is certain
(b) should indicate what the threat is, what
(c) action should be taken, by whom and when
(d) are best if they come from a single source
(e) all of the above.
Answer: (b)
Flood warnings should provide information on what the threat is, what action should be taken, by whom and when. While it is desirable for flood warnings to be accurate, warnings are predictions about the future, so there is inevitably some uncertainty. Accuracy needs to be balanced with timeliness, to allow enough time for appropriate action. Warnings are most likely to reach different audiences and to be heeded if they come from multiple trusted sources.

Flood risk refers to:
(a) the chance of a flood occurring
(b) the number of people and properties exposed to floodwaters if a flood occurs
(c) the vulnerability of people and properties that are exposed to floodwaters
(d) all of the above.
Answer: (d)
Flood risk includes both the chance (or probability) of a flood occurring, and the consequences if a flood occurs. The consequences of a flood are in turn affected by the number of people and properties exposed to floodwaters for a flood of a particular size, and the vulnerability of those people and properties. For example, a river might burst its banks regularly, but if this flooding occurs in an isolated area where there are no people or infrastructure, then the risk is low. Similarly, a river might flood very rarely, but if many people and properties are located near this river and they live in dwellings that are vulnerable to water damage, then the flood risk will be greater.

Which of the following can reduce the risk of flooding?
(a) zonings and building regulations for new developments
(b) dams, detention basins and levees
(c) flood awareness and education programs
(d) all of the above.
Answer: (d)
Flood risk in new developments can be reduced by restricting the location of development (zonings) and placing controls (regulations) on development. In existing developed areas, risk can be reduced by modifying flood behaviour (for example, through dams, detention basins, levees, waterway modifications), property modification measures (for example, land filling, flood proofing, house raising, removing developments), and response modification measures (for example, upgrading flood evacuation routes, flood warnings, flood evacuation planning, flood education programs).

The Probable Maximum Flood is:
(a) an estimation of the largest possible flood that could occur at a particular location
(b) the maximum flood experienced in the last 100 years
(c) the maximum flood experienced in the last 200 years
(d) the maximum flood experienced since flood records have existed.
Answer: (d)
The Probable Maximum Flood (PMF) is an estimate of the largest possible flood that could occur at a particular location, under the most severe meteorological and hydrological conditions as they are currently understood.

In the future, which of the following is expected to increase the risk of flooding?
(a) population growth
(b) urbanization
(c) climate change
(d) all of the above.
Answer: (d)
In the future, climate change is likely to result in an increased chance of flash floods and coastal inundation. Australia’s growing population and urbanization are likely to place increased pressure on our waterways and to increase the chance of flooding in cities and the number of properties and people exposed to floodwaters.

In the future, which of the following is unlikely?
(a) There will be an increased chance of flash flooding and coastal inundation.
(b) Flood risk will increase due to population growth and urbanization.
(c) Improvements in flood forecasting and warning technologies will reduce the impacts of floods.
(d) We will be able to eliminate the risk of flooding.
Answer: (d)
It is not possible to eliminate the risk of flooding. Indeed, it is likely that flood risk will increase in the future due to climate change, population growth and urbanization. However, we can better manage flood risk through improvements in flood forecasting and warning technologies, as well as improved land use planning, floodplain management and integrated water management.

(a) sand storms
(b) lower precipitation
(c) higher precipitation
(d) none of the above
Answer: (c)

What can cause a tsunami?
(a) Landslide
(b) Underwater earthquake
(c) Volcanic eruption
(d) All of the above

(a) Afforestation
(b) Cutting the forests
(c) Tilling the land
(d) Removing the top soil
Answer: (a)
Afforestation is the establishment of a forest or stand of trees in an area where there was no forest. Reforestation is the reestablishment of forest cover, either naturally (by natural seeding, coppice, or root suckers) or artificially (by direct seeding or planting).
Afforestation Trees are planted near to the river. This means greater interception of rainwater and lower river discharge. This is a relatively low cost option, which enhances the environmental quality of the drainage basin.

101) Which type of star is maintained by the pressure of an electron gas?
(a) Main Sequence Star
(b) White Dwarf
(c) Neutron Star
(d) Black Hole
Answer: (b)
White dwarfs are stars supported by pressure of degenerate electron gas. i.e. in their interiors thermal energy kT is much smaller then Fermi energy Ep. We shall derive the equations of structure of white dwarfs, sometimes called degenerate dwarfs, in the limiting case when their thermal pressure may be neglected, but the degenerate electron gas may be either non-relativistic. somewhat relativistic. or ultra-relativistic.

109) The precession of the Earth refers to the:
(a) change from night to day.
(b) Earth’s motion around the sun.
(c) change in orientation of the Earth’s axis.
(d) effect of the moon on the Earth’s orbit.
Answer: (c)
Precession is the change in orientation of the Earth’s rotational axis. The precession cycle takes about 19,000 – 23,000 years. Precession is caused by two factors: a wobble of the Earth’s axis and a turning around of the elliptical orbit of the Earth itself (Thomas, 2002). Obliquity affected the tilt of the Earth’s axis, precession affects the direction of the Earth’s axis. The change in the axis location changes the dates of perihelion (closest distance from sun) and aphelion (farthest distance from sun), and this increases the seasonal contrast in one hemisphere while decreasing it in the other hemisphere ( Kaufman, 2002). currently, the Earth is closest to the sun in the northern hemisphere winter, which makes the winters there less severe (Thomas, 2002). Another consequence of precession is a shift in the celestial poles. 5000 years ago the North Star was Thuban in the constellation Draco. Currently the North Star is Polaris in the constellation Ursa Minor.

(a) the eclipse path.
(b) ecliptic.
(c) diurnal.
(d) solstice.
Answer: (b)
The ecliptic is an imaginary line on the sky that marks the annual path of the sun. It is the projection of Earth’s orbit onto the celestial sphere.

132) The angular distance between a planet and the Sun, as viewed from the Earth, is called
(a) angle of inclination.
(b) elongation.
(c) latitude.
(d) opposition.
Answer: (b)
Elongation is the angular distance between the sun, and another object such a moon or a planet as seen from earth. There are several special names for these angular distances. The different names of these angles depend on the status, inferior or superior, of the planet. The planets closer to the sun than the earth are called inferior planets. The planets farther away from the sun than earth are called superior planets.
Elongation is measured from earth as the angle between the sun and the planet. Sometimes the apparent relative position of a planet in relation to the sun is called the aspect, or configuration, of a planet.

133) Which of the following has the highest density?
(a) Earth
(b) Venus
(c) Mars
(d) Jupiter
Answer: (a)
Earth has the highest density of any planet in the Solar System, at 5.514 g/cm3. This is considered the standard by which other planet’s densities are measured. In addition, the combination of Earth’s size, mass and density also results in a surface gravity of 9.8 m/s². This is also used as a the standard (one g) when measuring the surface gravity of other planets.

134) Which of the following planets is NOT a terrestrial planet?
(a) Earth
(b) Jupiter
(c) Mars
(d) Mercury
Answer: (b)
The term terrestrial planet is derived from the Latin “Terra” (i.e. Earth). Terrestrial planets are therefore those that are “Earth-like”, meaning they are similar in structure and composition to planet Earth. All those planets found within the Inner Solar System – Mercury, Venus, Earth and Mars – are examples of terrestrial planets. Each are composed primarily of silicate rock and metal, which is differentiated between a dense, metallic core and a silicate mantle.

135) Why do we see lunar eclipses much more often than solar eclipses?
(a) Lunar eclipses occur more often than solar eclipses.
(b) Lunar eclipses last longer than solar eclipses.
(c) The lunar eclipse is visible to much more of the Earth than a solar eclipse.
(d) The moon is closer to the Earth than the sun.
Answer: (c)
Lunar and solar eclipses occur with about equal frequency. Lunar eclipses are more widely visible because Earth casts a much larger shadow on the Moon during a lunar eclipse than the Moon casts on Earth during a solar eclipse. As a result, we are more likely to see a lunar eclipse than a solar eclipse.

136) A star like object with a very large red shift is a
(a) Neutron star.
(b) Nova.
(c) Quasar.
(d) Supernova.
Answer: (c)
Quasars: In the 1930’s, Edwin Hubble discovered that all galaxies have a positive redshift. In other words, all galaxies were receding from the Milky Way.

The Van Allen belts are a collection of charged particles, gathered in place by Earth’s magnetic field. They can wax and wane in response to incoming energy from the sun, sometimes swelling up enough to expose satellites in low-Earth orbit to damaging radiation.

139) A coordinate system based on the ecliptic system is especially useful for the studies of
(a) Planets
(b) Stars
(c) The Milky Way
(d) Galaxies
Answer: (a)

140) The mean distance of the earth from the sun in astronomical units is:
(a) 3.7 (b) 10
(c) 1 (d) 101
Answer: (c)
In astronomy, an astronomical unit is defined as the average distance from the Sun to the Earth, or about 150 million kilometers (93 million miles). You can abbreviate astronomical unit as AU.
Since the distances in astronomy are so vast, astronomers use this measurement to bring the size of numbers down.
For example, Earth is 1 au from the Sun, and Mars is 1.523 AU. That’s much easier than saying that Mars is 227,939,000 km away from the Sun.

141) What process produces a star’s energy?
(a) hydrogen and oxygen combustion
(b) nuclear fusion
(c) neutron beta decay
(d) nuclear fission
Answer: (b)
The enormous luminous energy of the stars comes from nuclear fusion processes in their centers. Depending upon the age and mass of a star, the energy may come from proton-proton fusion, helium fusion, or the carbon cycle.

142) What is the most distant object in the sky that the human eye can see without optical instruments?
(a) The Horsehead Nebula
(b) The Andromeda Galaxy
(c) The Sagittarius Constellation
(d) The Aurora Borealis
Answer: (b)
The Andromeda Galaxy (M31) is the closest large galaxy to the Milky Way and is one of a few galaxies that can be seen unaided from the Earth. In approximately 4.5 billion years the Andromeda Galaxy and the Milky Way are expected to collide and the result will be a giant elliptical galaxy. Andromeda is accompanied by 14 dwarf galaxies, including M32, M110, and possibly M33 (The Triangulum Galaxy).

143) Which civilization developed and implemented the first solar calendar?
(a) Babylonian
(b) Greek
(c) Egyptian
(d) Aztec
Answer: (c)
A solar calendar is a calendar whose dates indicate the position of the earth on its revolution around the sun and is based on the seasonal year of approximately 365 1/4 days, the time it takes the Earth to revolve once around the Sun. The Egyptians appear to have been the first to develop a solar calendar, using as a fixed point the annual sunrise reappearance of the Dog Star — Sirius, or Sothis — in the eastern sky, which coincided with the annual flooding of the Nile River. They constructed a calendar of 365 days, consisting of 12 months of 30 days each, with 5 days added at the year’s end. The Egyptians’ failure to account for the extra fraction of a day, however, caused their calendar to drift gradually into error.

144) What is the HOTTEST region of the sun?
(a) The core
(b) The photosphere
(c) The chromospheres
(d) The corona
Answer: (d)
The corona is the outermost layer of the Sun, starting at about 1300 miles (2100 km) above the solar surface (the photosphere) The temperature in the corona is 500,000 K (900,000 degrees F, 500,000 degrees C) or more, up to a few million K. The corona cannot be seen with the naked eye except during a total solar eclipse, or with the use of a coronagraph. The corona does not have an upper limit.
A study published in 2012 in Nature Communications by researchers at Northumbria University found a possible mechanism that causes some stars to have a corona that is almost 200 times hotter than their photosphere (the star’s surface).

145) The same side of the moon always faces the Earth because:
(a) the moon is not rotating about its axis.
(b) the moon’s motion was fixed at its creation by the laws of inertia.
(c) tidal forces keep the moon’s rotation and orbiting motion in sync with each other.
(d) the moon’s magnetic poles keep aligned with the Earth’s magnetic field.
Answer: (b)

146) The resolving power of a telescope depends on the:
(a) focal ratio
(b) diameter of the objective
(c) magnification
(d) focal length
Answer: (b)
The resolving power of a telescope depends on the diameter of the telescope’s light-gathering apparatus, or objective. In a refracting telescope, the objective lens is the first lens the light passes through. In a reflecting telescope, the objective is the telescope’s primary mirror. In a Schmidt-Cassegrain telescope, the objective is also the primary mirror. As the diameter of the telescope’s objective increases, the resolving power increases.

147) On a clear, dark, moonless night, approximately how many stars can be seen with the naked eye?
(a) 300 (b) 1,000
(c) 3,000 (d) 10,000

On any clear dark moonless night a person can see about 3000 stars of our galaxy without the aid of a telescope

148) The study of the origin and evolution of the universe is known as:
(a) Tomography
(b) cystoscopy
(c) cryology
(d) cosmology
Answer: (d)
Cosmology is the branch of astronomy involving the origin and evolution of the universe, from the Big Bang to today and on into the future. According to NASA, the definition of cosmology is “the scientific study of the large scale properties of the universe as a whole.”

149) According to Kepler’s Laws, all orbits of the planets are:
(a) ellipses
(b) parabolas
(c) hyperbolas
(d) square
Answer: (a)
Johannes Kepler, working with data painstakingly collected by Tycho Brahe without the aid of a telescope, developed three laws which described the motion of the planets across the sky.
1. The Law of Orbits: All planets move in elliptical orbits, with the sun at one focus.
2. The Law of Areas: A line that connects a planet to the sun sweeps out equal areas in equal times.
3. The Law of Periods: The square of the period of any planet is proportional to the cube of the semimajor axis of its orbit.
Kepler’s laws were derived for orbits around the sun, but they apply to satellite orbits as well.

75) Where do most of Asteroids lie? (CSS-2009)
(a) In asteroid belt between the orbits of Mars and Jupiter
(b) In asteroid belt between the orbits of Mars and Venus
(c) In asteroid belt between the orbits of Jupiter and Venus
(d) Everywhere in the sky
(e) None of these
Answer: (a)
Most asteroids lie in a vast ring between the orbits of Mars and Jupiter. This main asteroid belt holds more than 200 asteroids larger than 60 miles (100 kilometers) in diameter. Scientists estimate the asteroid belt also contains more than 750,000 asteroids larger than three-fifths of a mile (1 km) in diameter and millions of smaller ones. Not everything in the main belt is an asteroid — for instance, comets have recently been discovered there, and Ceres, once thought of only as an asteroid, is now also considered a dwarf planet.

76) The largest circular storm in our solar system is on the surface of which of the following planets?
(a) Jupiter
(b) Venus
(c) Uranus
(d) Earth
Answer: (a)
Jupiter boasts the largest storm in the Solar System . It is called the Great Red Spot and has been observed for hundreds of years that kind of storm is dwarfed by the Great Red Spot, a gigantic storm in Jupiter. There, gigantic means twice as wide as Earth. Today, scientists know the Great Red Spot is there and it’s been there for a while, but they still struggle to learn what causes its swirl of reddish hues.

77) The biggest asteroid known is:
(a) Vesta
(b) Icarus
(c) Ceres
(d) Eros
Answer: (c)
Ceres, a dwarf planet and the largest asteroid in the solar system yet known. Discovered in 1801 and first thought to be a planet and then an asteroid, we now call Ceres a dwarf planet. Gravitational forces from Jupiter billions of years ago prevented it from becoming a full-fledged planet. But Ceres has more in common with Earth and Mars than its rocky neighbors in the main asteroid belt. There may even be water ice buried under Ceres’ crust.

78) Rounded to the nearest day, the Mercurian year is equal to:
(a) 111 days
(b) 87.97 days
(c) 50 days
(d) 25 days
Answer: (b)
Mercurian Year: A year on Mercury takes 87.97 Earth days; it takes 87.97 Earth days for Mercury to orbit the sun once

79) One of the largest volcanoes in our solar system-if not the largest-is named Olympus Mons. This volcano is located on:
(a) Jupiter’s moon Callisto
(b) Venus
(c) Saturn’s moon Titan
(d) Mars
Answer: (d)
Olympus Mons is the largest volcano in the solar system. The massive Martian mountain towers high above the surrounding plains of the red planet, and may be biding its time until the next eruption. Olympus Mons rises three times higher than Earth’s highest mountain, Mount Everest, whose peak is 5.5 miles above sea level.

80) One Jupiter day is equal to which of the following?
(a) 30 hrs 40 min
(b) 9 hrs 50 min
(c) 3 hrs 20 min
(d) 52 hrs 10 min

(a) a conjunction
(b) an opposition
(c) a sidereal period
(d) a synodic period.
Answer: (d)
Synodic period , in astronomy, length of time during which a body in the solar system makes one orbit of the sun relative to the earth, i.e. The synodic period of the moon, which is called the lunar month, or lunation, is 291/2 days long; it is longer than the sidereal month.

Answer: (d)

83) The sunspot cycle is:
(a) 3 years
(b) 11 years
(c) 26 years
(d) 49 years
Answer: (b)

The amount of magnetic flux that rises up to the Sun’s surface varies with time in a cycle called the solar cycle. This cycle lasts 11 years on average. This cycle is sometimes referred to as the sunspot cycle.

84) The Hertzsprung-Russel Diagram of stars DIRECTLY compares what TWO of the following properties of stars?
(a) size
(b) temperature
(c) luminosity
(d) Both b & c
Answer: (d)
One of the most useful and powerful plots in astrophysics is the Hertzsprung-Russell diagram (hereafter called the H-R diagram). It originated in 1911 when the Danish astronomer, Ejnar Hertzsprung, plotted the absolute magnitude of stars against their color (hence effective temperature). Independently in 1913 the American astronomer Henry Norris Russell used spectral class against absolute magnitude. Their resultant plots showed that the relationship between temperature and luminosity of a star was not random but instead appeared to fall into distinct groups.

The majority of stars, including our Sun, are found along a region called the Main Sequence. Main Sequence stars vary widely in effective temperature but the hotter they are, the more luminous they are, hence the main sequence tends to follow a band going from the bottom right of the diagram to the top left. These stars are fusing hydrogen to helium in their cores. Stars spend the bulk of their existence as main sequence stars. Other major groups of stars found on the H-R diagram are the giants and supergiants; luminous stars that have evolved off the main sequence, and the white dwarfs. Whilst each of these types is discussed in detail in later pages we can use their positions on the H-R diagram to infer some of their properties.

85) The Andromeda Galaxy is which of the following types of galaxies?
(a) elliptical
(b) spiral
(c) barred-spiral
(d) irregular
Answer: (b)
The Andromeda Galaxy also known as Messier 31, M31, or NGC 224, is a spiral galaxy approximately 780 kilo parsecs (2.5 million light-years) from Earth

86) About how many light years across is the Milky Way? Is it:
(a) 1,000
(b) 10,000
(c) 100,000
(d) 1,000,000
Answer: (c)
100 000 light years across
A light-year is precisely equal to a whole number of meters, namely 9460730472580800 m or approximately 9.46073 1015 m. That’s the distance traveled by light in a vacuum, at a speed of 299792458 m/s, during a “scientific year” of 31557600 s. All these numbers are exact… In particular, “Einstein’s Constant” is exactly c = 299792458 m/s, because of the latest definition of the meter, officially adopted in 1983.

87) Who was the first man to classify stars according to their brightness. Was it:
(a) Aristarchus
(b) Pythagoras
(c) Copernicus
(d) Hipparchus
Answer: (d)
The first person to classify stars by their apparent magnitude (brightness) was Hipparchus in about 130 BC. He divided the stars into classes based on how bright they appeared in the night sky. The brightest stars were classified as magnitude 1, those that were just visible to the naked eye as magnitude 6. In practice the intensity of a magnitude 1 star is 100 times that of a magnitude 6 star, so the 5 magnitude steps correspond to a multiple of 100. For a geometric series of magnitudes each magnitude must be a times the intensity of the previous one with a5 – 100. This means that going up one magnitude increases the intensity by a factor of a = 2.51. So magnitude 3 is 2.51 times as intense as magnitude 4 and so on.

88) For what reason was the Schmidt telescope specially built? Was it to serve as:
(a) a sky camera
(b) a radio telescope
(c) an optical telescope
(d) a solar telescope
Answer: (a)

A Schmidt camera, also referred to as the Schmidt telescope, is a catadioptric astrophotographic telescope designed to provide wide fields of view with limited aberrations. The design was invented by Bernhard Schmidt in 1930.

89) The greatest distance of a planet from the sun is called what? Is it the planet’s:
(a) aphelion
(b) perihelion
(c) helix
(d) eccentricity
Answer: (a)
The closest point to the Sun in a planet’s orbit is called perihelion. The furthest point is called aphelion

90) How is the atmospheric pressure of Mars as compared to the atmospheric pressure of the earth? Is it:
(a) about the same as the earth’s
(b) about 100 times as great as the earth’s
(c) about 1/200th that of the earth’s
(d) half as much as that of the earth’s
Answer: (c)
The atmosphere and (probably) the interior of Mars differ substantially from that of the Earth. The atmosphere is much less dense and of different composition, and it is unlikely that the core is molten.
The atmosphere has a pressure at the surface that is only 1/200 that of Earth. The primary component of the atmosphere is carbon dioxide (95%), with the remainder mostly nitrogen. Seasonal heating drives strong winds that can reach 100 mph or more, stirring up large dust storms. Clouds form in the atmosphere, but liquid water cannot exist at the ambient pressure and temperature of the Martian surface: water goes directly between solid and vapor phases without becoming liquid.

91) A typical galaxy, such as our Milky Way galaxy, contains how many billion stars? Is it approximately:
(a) 10 billion
(b) 40 billion
(c) 400 billion
(d) 800 billion
Answer: (c)
According to astronomers, our Milky Way is an average-sized barred spiral galaxy measuring up to 120,000 light-years across. Our Sun is located about 27,000 light-years from the galactic core in the Orion arm. Astronomers estimate that the Milky Way contains up to 400 billion stars of various sizes and brightness.
According to astronomers, there are probably more than 170 billion galaxies in the observable Universe, stretching out into a region of space 13.8 billion light-years away from us in all directions.

92) A comet’s tail points in which direction?
(a) toward the sun
(b) toward the earth
(c) behind the comet in its orbit
(d) away from the sun
Answer: (d)
Comet tails are expansions of the coma. Comet tails point away from the Sun, regardless of the direction in which the comet is traveling. Comets have two tails because escaping gas and dust are influenced by the Sun in slightly different ways, and the tails point in slightly different directions.

93) Spectral line splitting due to the influence of magnetic fields is called:
(a) Boltzmann Effect
(b) Zeeman Effect
(c) Planck Effect
(d) Zanstra’s Effect
Answer: (b)
The Zeeman effect is the splitting of a spectral line by a magnetic field. That is, if an atomic spectral line of 400 nm was considered under normal conditions, in a strong magnetic field, because of the Zeeman effect, the spectral line would be split to yield a more energetic line and a less energetic line, in addition to the original line at 400 nm.

94) Which of the following is true for ORION? Orion is:
(a) the brightest star in the sky

Atmosphere of the Moon might be electro statically levitated moon dust. These tiny particles are constantly leaping up and down off the surface of the Moon.

4) Who gave the first evidence of the Big- Bang theory?

(a) Edwin Hubble
(b) Albert Einstein
(c) S. Chandrasekhar
(d) Stephen Hawking
Answer: (a)
The Hubble Space Telescope was named after astronomer Edwin Powell Hubble (1889–1953), who made some of the most important discoveries in modern astronomy. Dr. Hubble determined that the farther a galaxy is from Earth, the faster it appears to move away. This notion of an “expanding” universe formed the basis of the Big Bang theory, which states that the universe began with an intense burst of energy at a single moment in time — and has been expanding ever since.

(a) 50 Million years
(b) 100 Million years
(c) 250 Million years
(d) 365 Million years
Answer: (c)
the Sun is dragging us around the galaxy at around 800,000km/h, taking around 250 million years to complete a single orbit.
That means our Solar System has made around 18 complete circuits since it was formed around 4.5 billion years ago.

9): The planet having the largest diameter is

(a) Earth
(b) Jupiter
(c) Venus
(d) Uranus
Answer: (b)
Jupiter is composed primarily of gaseous and liquid matter. It is the largest of the four giant planets in the Solar System and hence its largest planet. It has a diameter of 142,984 km (88,846 mi) at its equator

10) The planet Mercury completes one rotation around the sun is (CSS 2010)

(a) 88 days
(b) 365 days
(c) 98 days
(d) 60 days
(e) None of these
Answer: (a)
A year on Mercury is just 88 days long. One solar day (the time from noon to noon on the planet’s surface) on Mercury lasts the equivalent of 176 Earth days while the sidereal day (the time for 1 rotation in relation to a fixed point) lasts 59 Earth days. Mercury is nearly tidally locked to the Sun and over time this has slowed the rotation of the planet to almost match its orbit around the Sun. Mercury also has the highest orbital eccentricity of all the planets with its distance from the Sun ranging from 46 to 70 million km.

11) The biggest planet in our solar system is (CSS 2013)

(a) Venus
(b) Pluto
(c) Jupiter
(d) None of these

13) Which of the following explains the reason why there is no total eclipse of the sun? (CSS 2009)

(a) Size of the earth in relation to that of moon
(b) Orbit of moon around earth
(c) Direction of rotation of earth around sun
(d) Area of the sun covered by the moon
(e) None of these
Answer: (d)
A solar eclipse occurs when the moon gets between Earth and the sun, and the moon casts a shadow over Earth. A solar eclipse can only take place at the phase of new moon, when the moon passes directly between the sun and Earth and its shadows fall upon Earth’s surface.

14) The sun produces most of its energy by (CSS 2012)

(a) Nuclear fusion which involves converting “H” to “He”
(b) Nuclear fission involving the burning of uranium & plutonium
(c) Nuclear fission involving the combining of uranium and palladium
(d) None of these
Answer: (a)
Sun, like all stars, is able to create energy because it is essentially a massive fusion reaction.
The core of the Sun is the region that extends from the center to about 20–25% of the solar radius. It is here, in the core, where energy is produced by hydrogen atoms (H) being converted into molecules of helium (He) This is possible thanks to the extreme pressure and temperature that exists within the core, which are estimated to be the equivalent of 250 billion atmospheres (25.33 trillion KPa) and 15.7 million kelvin, respectively.

15) Although the mass of a man on moon remains same as on the earth he will (CSS 2012)

(a) Be much happier there

Every day, the Sun, Moon, planets, and stars appear to rise in the east and set in the west. Actually, these celestial objects aren’t moving that fast, but Earth is. It spins on its axis from west to east approximately every 24 hours.
Because we are standing on Earth’s surface, we move along with it. To us, it appears as if everything in the sky is moving from east to west.

24): The body burning like a star and coming towards the earth

(a) Comet
(b) Meteor
(c) Ceres
(d) Satellites
Answer: (b)
Fleeting trails of light are called meteors or shooting stars and they are created by small particles, some no bigger than a grain of rice, as they are completely burned up high in the atmosphere: about 100 km (or 60 miles) above the Earth. They are over literally in the blink of an eye. Space debris is collectively termed meteoroids, those larger fragments that reach the ground are called meteorites. Very big meteoroids are also known as asteroids. If one collides with Earth it would cause a major catastrophe.

37) Orbital period of the planet Mercury around the sun is: (CSS 2009)

(a) 88 days
(b) 365 days
(c) 2 years
(d) 98 days
(e) None of these
Answer: (a)
Mercury has an orbital period of 88 days (87.969 to be exact), which means a single year is 88 Earth days – or the equivalent of about 0.241 Earth years. But here’s the thing.
