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.

Seasons are generated by (CSS-2012)
(a) The movement of sun around the Milky Way
(b) The movement of the earth around the sun
(c) Relativistic Quantum

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.

(c) Up to 500 miles an hour (800 kilometers an hour
(d.) Up to 1,000 miles an hour (1,600 kilometers an hour)
Answer: (c)
Tsunamis race across the sea at up to 500 miles (805 kilometers) an hour—about as fast as a jet airplane. At that pace they can cross the entire expanse of the Pacific Ocean in less than a day.

Can you detect a tsunami in the open ocean?
(a) Yes
(b) No
Answer: (b)
No. In the open ocean, the wave length of a tsunami is hundreds of miles long and only a few feet high. Boaters are safer out at sea during a tsunami than close to shore or tied up at port.

Where was the largest tsunami in history recorded?
(a) India
(b) Philippines
(c) Chile
(d) Japan
Answer: (d)
In 1971 a wall of water 278 feet (84.7 meters) high surged past Ishigaki Island, Japan. It moved a 750-block of coral 1.5 miles (2.4 kilometers) closer to shore but did little other damage.

What is frequently a warning sign of an impending tsunami?
(a) Winds suddenly change direction
(b) The sky suddenly clears
(c) Seawater suddenly retreats from the shore
(d) All of the above
Answer: (c)
If the tsunami’s trough reaches shore first, it sucks the water seaward, exposing the seafloor suddenly. The wave’s crest usually hits shore about five minutes later. Recognizing this phenomenon—and getting to higher ground immediately—can save lives.

At present there are 99 Wildlife Sanctuaries in Pakistan

The death of the last individual of a species is called_______.
(a) Extinction
(b) Clad
(c) Neither (a) nor (b)
(d) Species diversity
Answer: (a)
In biology and ecology, extinction is the end of an organism or of a group of organisms (taxon), normally a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point.

Which one of the following is not a fossil fuel?
(a) Natural gas
(b) Petrol
(c) Coal
(d) Uranium
Answer: (d)
Fossil fuels are sources of energy that have developed within the earth over millions of years. Because fossil fuels – oil, natural gas, and coal – take so long to form, they are considered nonrenewable

Biogas generation is mainly based on the principle of_______.
(a) Fermentation
(b) Degradation
(c) Putrification
(d) Both (a) and (b)
Answer: (a)
The biogas plant operating on the principle of a wet anaerobic fermentation process was selected for the determination of the composition of in-put raw material which is determinative for the final biogas quality. The biogas plant is designed as an accumulation through-flow device. The biogas production takes place during the wet fermentation process in the mesophile operation (average temperature 40°C). The produced biogas is used in a cogeneration unit. The biogas plant operates in automatic mode.

Floods can be prevented by_______.
(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.

The outer satellite, Deimos, is about 4 mi (6 km) in diameter.

58) All stars are of the same color
(False)

59) Our galaxy milky way is shaped like a large thick concave lens with a large central bulge (CSS 2002)
(True)

60) The coldest planet of the solar system is: (CSS 2000)
(a) Earth
(b) Venus
(c) Neptune d) Pluto
(e) None of these
Answer: (c)
In the past, the title for “most frigid body” went to Pluto, as it was the farthest then-designated planet from the Sun. However, due to the IAU’s decision in 2006 to reclassify Pluto as a “dwarf planet”, the title has since passed to Neptune. As the eight planet from our Sun, it is now the outermost planet in the Solar System, and hence the coldest.

61) Venus is the smallest planet of the solar system. (CSS 1999)
(False)

62) Black hole is a hypothetical region of space having a gravitational pull so great that no matter or radiation can escape from it. (CSS 1998)

(c) 4 Moons
(d) None of these
Answer: (b)
The moons of Mars are Phobos and Deimos. Both moons were discovered in 1877 by Asaph Hall Asaph Hall was about to give up his frustrating search for a Martian moon one August night in 1877, but his wife Angelina urged him on. He discovered Deimos the next night, and Phobos six nights after that. Ninety-four years later, NASA’s Mariner 9 spacecraft got a much better look at the two moons from its orbit around Mars. The dominant feature on Phobos, it found, was a crater 10 km (6 miles) wide — nearly half the width of the moon itself. It was given Angelina’s maiden name: Stickney.

(a) Orion
(b) Columbia
(c) Canis Major
(d) Taurus
(e) None of these
Answer: (a)
(Canis Major is a constellation in the southern sky. Its name means “the greater dog” in Latin.) Orion, which is located on the celestial equator, is one of the most prominent and recognizable constellations in the sky and can be seen throughout the world.

74) 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

Answer: (b)

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
Answer: (b)

81) The time interval between two successive occurrences of a specific type of alignment of a planet (or the moon) with the sun and the earth is referred to as:
(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.

82) Of the following four times, which one best represents the time it takes energy generated in the core of the sun to reach the surface of the sun and be radiated?
(a) Three minutes
(b) Thirty days
(c) One thousand years
(d) One million years
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
(b) a constellation
(c) the name given to a NASA spacecraft
(d) an asteroid
Answer: (b)

95) Which of the following men wrote the book “On the Revolutions of the Heavenly Spheres”?
(a) Kepler
(b) Euclid
(c) Copernicus
(d) Newton
Answer: (c)

De revolutionibus orbium coelestium (On the Revolutions of the Heavenly Spheres) is the seminal work on the heliocentric theory of the Renaissance astronomer Nicolaus Copernicus (1473–1543).

96) The most distant planet in the solar system is (CSS 1995)
(a) Mars
(b) Pluto
(c) Jupiter
(d) None of these
Answer: (d)
New Dwarf Planet In Our Solar System May Be The Farthest One Yet. Object V774104 was discovered in late October, 2015, and is one of the most distant objects ever detected in the solar system. It appears to be about half the size of Pluto, but with an orbit two to three times larger than Pluto’s. (Nov 12, 2015)

97) The 2.7 Kelvin cosmic background radiation is concentrated in the:
(a) radio wavelengths
(b) infrared
(c) visible
(d) ultraviolet
Answer: (a)

98) If you were watching a star collapsing to form a black hole, the light would disappear because it:
(a) is strongly red shifted
(b) is strongly blue shifted
(c) its color suddenly becomes black
(d) none of the above
Answer: (a)

99) The Magellanic Clouds are
(a) irregular galaxies
(b) spiral galaxies
(c) elliptical galaxies
(d) large clouds of gas and dust
Answer: (a)
The Magellanic Clouds are comprised of two irregular galaxies, the Large Magellanic Cloud (LMC) and the Small Magellanic Cloud (SMC), which orbit the Milky Way once every 1,500 million years and each other once every 900 million years. Lying only about 200,000 light years away, they were the closest known galaxies to the Milky Way until recently, when the Sagittarius and Canis Major dwarf galaxies were discovered and found to be even closer.

General Knowledge, MCQs / Q&A

10 Important Climate Change Facts

1) Temperatures are breaking records around the world:

The 21st century has seen the most temperature records broken in recorded history. 2016 was the hottest year on record since 1880, according to NASA, with average temperatures measuring 1.78 degrees Fahrenheit (0.99 degrees Celsius) warmer than the mid-20th century mean Since the 1950s, every continent has warmed substantially. NASA’s latest visualizations, above, make that reality stark.

2) There is no scientific debate about the reality of climate change:

Multiple studies show that a massive 97 per cent of researchers believe global warming is happening But climate change is considered only the third most serious issue facing the world by the world’s population, behind international terrorism and poverty, hunger and the lack of drinking water

3) Arctic sea ice and glaciers are melting:

Arctic sea ice coverage has shrunk every decade since 1979 by 3.5 to 4.1 per cent. Glaciers have also been in retreat, including in major mountain ranges like the Alps, Himalayas and Rockies. In 2017, Arctic sea ice reached a record low for the third straight running

4) Sea levels are rising at their fastest rate in 2,000 years:

Levels are currently rising at their fastest rate for more than 2,000 years and the current rate of change is 3.4mm a year. In July, a massive crack in the Larson C ice shelf finally gave way sending a 5,800 square km section of ice into the ocean. The newly formed iceberg is nearly four times the size of London.

5) Climate change will lead to a refugee crisis:

An average of 21.5 million people have been forcibly displaced since 2008 due to climate changed-related weather hazards, according to the United Nations High Commissioner for Refugees.

6) Two-thirds of the Great Barrier Reef has been damaged as a result of climate change:

In April 2017, it was revealed that two-thirds of Australia’s Great Barrier Reef has been severely damaged by coral bleaching. As a result, the coral loses its vibrant appearance, turns white and becomes weaker. Scientists say it will be hard for the damaged coral to recover.

7) The ocean is 26 percent more acidic than before the Industrial Revolution:

The pH of ocean surface water has decreased by 0.1, which makes them 26 percent more acidic now than at the beginning of the Industrial Revolution. The waters are more acidic now that at any other point in the last 300,000 years.

8) Global flooding could triple by 2030:

The number of people exposed to flooding each year is at risk of tripling from 21 million to 54 million by 2030, This would result in the economic costs of flooding increasing from £65 billion to around £340 billion.

9) More greenhouse gases are in our atmosphere than any time in human history:

The concentration of carbon dioxide in the atmosphere reached the milestone of 400 parts per million for the first time in 2015 and surged again to new records in 2016

10) Earth could warm by six degrees this century:

The Earth’s temperature will continue to rise so long as we continue to produce greenhouse gases. The estimates for how much temperature will increase by 2100 range from two degrees Celsius to as much as six degrees Celsius.

(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)

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

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.
