25 English Language Oddities

English /

Many cultures find that English might possibly be one of the most difficult languages to learn. Not, in fact, for its words, but for the fact that it has so many unusual and contradictory rules. Just looking over an English study book will tell you that so many odd ifs and buts apply to so many words that it is enough to drive one crazy. Here are 25 examples of the oddities in the English language.

25. “Rhythms” is the longest English word without the normal vowels, a, e, i, o, or u.24. Excluding derivatives, there are only two words in English that end -shion and (though many words end in this sound). These are cushion and fashion.23. “THEREIN” is a seven-letter word that contains thirteen words spelled using consecutive letters: the, he, her, er, here, I, there, ere, rein, re, in, therein, and herein.22. There is only one common word in English that has five vowels in a row: queueing.21. Soupspoons is the longest word that consists entirely of letters from the second half of alphabet.

20. “Almost” is the longest commonly used word in the English language with all the letters in alphabetical order.19. The longest uncommon word whose letters are in alphabetical order is the eight-letter Aegilops (a grass genus).18. The longest common single-word palindromes are deified, racecar, repaper, reviver, and rotator.17. “One thousand” contains the letter A, but none of the words from one to nine hundred ninety-nine has an A.16. “The sixth sick sheik’s sixth sheep’s sick” is said to be the toughest tongue twister in English.

15. Cwm (pronounced “koom”, defined as a steep-walled hollow on a hillside) is a rare case of a word used in English in which w is the nucleus vowel, as is crwth (pronounced “krooth”, a type of stringed instrument). Despite their origins in Welsh, they are accepted English words.14. “Asthma” and “isthmi” are the only six-letter words that begin and end with a vowel and have no other vowels between.13. The nine-word sequence I, in, sin, sing, sting, string, staring, starting (or starling), startling can be formed by successively adding one letter to the previous word.12. “Underground” and “underfund” are the only words in the English language that begin and end with the letters “und.”11. “Stewardesses” is the longest word that can be typed with only the left hand.

10. Antidisestablishmentarianism listed in the Oxford English Dictionary, was considered the longest English word for quite a long time, but today the medical term pneumonoultramicroscopicsilicovolcanoconiosis is usually considered to have the title, despite the fact that it was coined to provide an answer to the question ‘What is the longest English word?’.9. “Dreamt” is the only English word that ends in the letters “mt”.8. There are many words that feature all five regular vowels in alphabetical order, the commonest being abstemious, adventitious, facetious.7. The superlatively long word honorificabilitudinitatibus (27 letters) alternates consonants and vowels.6. “Fickleheaded” and “fiddledeedee” are the longest words consisting only of letters in the first half of the alphabet.

5. The two longest words with only one of the six vowels including y are the 15-letter defenselessness and respectlessness.4. “Forty” is the only number which has its letters in alphabetical order. “One” is the only number with its letters in reverse alphabetical order.3. Bookkeeper is the only word that has three consecutive doubled letters.2. Despite the assertions of a well-known puzzle, modern English does not have three common words ending in -gry. Angry and hungry are the only ones.1. “Ough” can be pronounced in eight different ways. The following sentence contains them all: “A rough-coated, dough-faced ploughman strode through the streets of Scarborough, coughing and hiccoughing thoughtfully.

Placement of Women in our society___are Women oppressed or dominant?

Articles, World /

What is Feminism?

Feminism is a literary movement of struggle, which endorses the set of ideologies and conviction systems. Feminists assert the equality between both sexes and the emancipation of oppressed women as an equal to men. The word ‘feminism’ can be a daunting and confusing word to some. Many people believe that feminism means hating men or wanting women to rule over everything– this could not be supplementary from the accuracy comas! Feminism simply means believing that men and women are equal, neither is better than the other and neither should be treated with more respect than the other – everyone should be equal on all levels, simple as that.

Why is Feminism important?

Importance of feminism

Feminism allows equal opportunities for both sexes. Gender roles (a set of conforming rules that say how a person should behave based on their gender) can be destructive to both men and women. The trendy belief is that women and girls are supposed to take care of the home while boys and men are meant to go out and supply for the family. Can you imagine not being allowed to go to school just because you’re a girl? Or being forced to stay at home and look after the house just because you’re a woman? This is the reality that many girls around the world face, even in this modern and urbanized era. Girls are not sent to school just because they are females and are not allowed to sustain the same rights and conveniences that boys hold. This implies the ideology of Patriarchy, means that women are innately inferior to men.

Even today when a woman gets pregnant, people anticipate and hope that it’s a baby boy. No one feels cheerfulness and joy on the birth of a baby girl. These are not biological but rather societal constructs. Feminists don’t deny the biological differences between men and women; but they don’t agree that how such differences as physical size, shape and body chemistry make men naturally superior to women.

What factors make women inferior and submissive to men.

There are abundant factors which chip into the inferiority and sedition of women in our society, but the foremost grounds are their women themselves have constructed their personalities as acquiescent and dependant on men. They have come to accept that they are good for nothing and therefore men have to look after them, be it their fathers, brothers or husbands. Submissive women their whole lives at first make themselves dependant on their fathers and then later in life on their husbands. They don’t even know the meaning of free sense of self, or how will it like to be free woman. Their personalities from the very start are skilfully constructed and they have been taught to internalize the societal norms. They have to deliver what society expects from them.

  • Effect of media:

Our media sadly is also showing the societal expectations from women, and under many circumstances they are oppressed to keep their mouths shut, no matter of how much pain she must be going through. Failures are expected from women, they’ll say: She couldn’t do it because she is a woman.

“Because I am a woman, I must make unusual effort to succeed. If I fail no one will say, “She doesn’t have what it take” in fact they’ll say, “A woman doesn’t have what it takes”.

Clare Bothe Luce.

On the other hand, Men are not permitted to fail at anything, because failure in any domain implies failure in one’s manhood.

To make this observable fact more lifelike, take the example of Disney’s renowned story Cinderella. It has been scrutinized that childhood stories like these make the young girls to live in the world of imagination and dystopia, because it equates femininity with submission, encouraging women to stomach abuse. Like Cinderella waits uncomplainingly for a man to come and rescue her, and view marriage as the only reward for “right” deportment. The character of Prince Charming which requires men to be wealthy rescuers of the poor beautiful girls is responsible to make their women happy.

          “Women’s chains are forged my men, not by anatomy”

Jane Fonda.

The singular rationale of women now is to get married; they don’t try to build their career because at the end they thought it is of no use since they’ll get married someday. After marriage the purpose of women shifted to their husbands. They try so hard to please their husbands and other people sometimes out of inevitability, that they forget their own self-esteem and reverence, whereas men never make women their sole spotlight, he has millions of other things to worry about. He always spends most of his time working and earning money, because it is his responsibility alone. Women’s soaring education (if she gets any) becomes useless after marriage if she doesn’t put it out practically.

It is only women who are told to make sacrifices and compromises, and in doing so they often settle for less than they warrant. Women have to be of specific age, colour and background to get a perfect match, while no such margins apply to men.

“Man endures pain as an undeserved punishment, while women accepts it as a natural heritage”

Anonymous

Solution to the problems:

Well, I am not saying that all women in our society are oppressed and not enjoying equal right as men does, but rather some are. Some husbands are that much supportive that they not only let their wives to do jobs, but they also fight for their feminist rights, and very evidence itself proves that Feminism is not gender biased. It is an ideology. It is a belief system which works for some people and not others. If a man is doing a job, then a woman also could. If a man is an educated doctor than a woman can also achieve that. If a man rides a motorcycle than a woman can also do so. Nothing in this world is gender biased, it is us, this society and our slender minded thinking that has made the matters that much complicated.

A woman should work, not because out of the need for money, but rather to keep herself busy and to focus her mind other than domestic issues. But nothing should be imposed on anyone if she wants to, than she should do whatever she wants because no society and nation as a whole can progress without their women participating in every field of life.

Gender should not be the hindrance in success.

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.

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

(a) Venus
(b) Pluto
(c) Jupiter
(d) None of these
Answer: (c)
In terms of mass, volume, and surface area, Jupiter is the biggest planet in our Solar System by a wide margin.
Size and Mass:
Jupiter’s mass, volume, surface area and mean circumference are 1.8981 x 1027 kg, 1.43128 x 1015 km3, 6.1419 x 1010 km2, and 4.39264 x 105 km respectively. To put that in perspective, Jupiter diameter is roughly 11 times that of Earth, and 2.5 the mass of all the other planets in the Solar System combined.

2) The universe is ———-. (CSS 1996)

(a) Stationary
(b) Expanding
(c) Contracting
(d) None of these
Answer: (b)
In June 2016, NASA and ESA scientists reported that the universe was found to be expanding 5% to 9% faster than thought earlier, based on studies using the Hubble Space Telescope

3) The atmosphere of moon consists of: (CSS 2013)

(a) . 90% Hydrogen, 10% Nitrogen
(b) . 80%Nitrogen, 20% Hydrogen
(c) 60% Nitrogen, 40%inert gases
(d) None of these
Answer: (d)
The Moon has no atmosphere. None. That’s why astronauts have to wear their spacesuits when they get outside of their spacecraft on the surface of the Moon.
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.

5) Which one of the following planets has largest number of natural satellites or moons?

(a) Jupiter
(b) Mars
(c) Saturn
(d) Venus
Answer: (a)
In the Solar System, there are 179 satellites. A majority of those moons belong to the planet of Jupiter, the second most belonging to Saturn.

6) Which of the following planets rotates clock wise?

(a) Mars
(b) Jupiter
(c) Venus
(d) Mercury
Answer: (c)
Venus is the only planet that rotates clockwise. Venus (radius 3,760.4 miles) is similar to Earth (radius 3,963.19 miles) in size and structure but spins very slowly; a day on Venus is 243 Earth days long.

8) The time taken by the Sun to revolve around the center of our galaxy is

(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
Answer: (c)

12) The atmosphere of moon consists of: (CSS 2013)

(a) 90% Hydrogen, 10% Nitrogen
(b) 80%Nitrogen, 20% Hydrogen
(c) 60% Nitrogen, 40%inert gases
(d) None of these
Answer: (d)
The Apollo 17 mission deployed an instrument called the Lunar Atmospheric Composition Experiment (LACE) on the moon’s surface. It detected small amounts of a number of atoms and molecules including helium, argon, and possibly neon, ammonia, methane and carbon dioxide.

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
(b) Weigh one sixth as much
(c) Weigh twice as much
(d) None of these
Answer: (b)
The Moon’s gravity is one sixth of the Earth’s gravity. A 120 kg astronaut weighs 1200 N on Earth. On the Moon they would weigh only 200 N. The astronaut’s mass is 120kg wherever they are.

(a) North to south
(b) South to north
(c) East to west
(d) West to east
Answer: (d)
The Earth rotates from the west towards east. As viewed from North Star or polestar Polaris, the Earth turns counter-clockwise. The North Pole, also known as the Geographic North Pole or Terrestrial North Pole, is the point in the Northern Hemisphere where the Earth’s axis of rotation meets its surface.

18): Name two planets which revolve around their axis from east to west

(a) Earth and Venus
(b) Mars and Earth
(c) Venus and Uranus
(d) Mars and Uranus

Planets have no light of their own and all of them expect Venus and Uranus, rotate upon their axis from west to east.

19) Our sun is classified as (CSS 2012)

(a) A Blue giant
(b) A Yellow dwarf
(c) Supernova
(d) None of these
Answer: (b)
The sun is classified as a G-type main-sequence star, or G dwarf star, or more imprecisely, a yellow dwarf. Actually, the sun — like other G-type stars — is white, but appears yellow through Earth’s atmosphere. Stars generally get bigger as they grow older

20): Name the planet which revolve approximately 90 degree with its orbital plane_.

(a) Neptune
(b) Venus
(c) Uranus
(d) Jupiter

(d) Scorpio
Answer: (b)

23): All the stars appear to move from

(a) North to south
(b) South to north
(c) East to west
(d) West to east
Answer: (c)
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.

(d) Optical telescope that uses electronic techniques to produce an image
Answer: (c)
Radio telescope is an astronomical instrument consisting of a radio receiver and an antenna system that is used to detect radio-frequency radiation emitted by extraterrestrial sources. Because radio wavelengths are much longer than those of visible light, radio telescopes must be very large in order to attain the resolution of optical telescopes.
The first radio telescope, built in 1937 by Grote Reber of Wheaton

33) Sun is a: (CSS 2011)

(a) Planet
(b) Comet
(c) Satellite
(d) Aurora
(e) None of these
Answer: (e)

(a) 4.5 billion years
(b) 5.5 billion years
(c) 6.5 billion years
(d) 7.5 billion years
(e) None of these
Answer: (e)
By studying several things, mostly meteorites, and using radioactive dating techniques, specifically looking at daughter isotopes, scientists have determined that the Solar System is 4.6 billion years old. Well, give or take a few million years. That age can be extended to most of the objects and material in the Solar System.

35) An eclipse of the sun occurs when (CSS 2011)

(a) The moon is between the sun and the earth
(b) The sun is between the earth and the moon
(c) The earth is between the sun and the moon
(d) The earth casts its shadow on the moon
(e) None of these
Answer: (a)
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.

36) Founder of modern astronomy was: (CSS 2009)

(a) Archimedes
(b) William Gilbert
(c) Nicolaus Copernicus
(d) Michael Faraday

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. Because of Mercury’s slow rotation (once every 58.646 days) and its rapid orbital speed (47.362 km/s), one day on Mercury actually works out to 175.96 Earth days.
