2. Which of the following is an example of direct source to study interior of the earth?
[A] Gravitation
[B] Sesimic activity
[C] Magnetic field
[D] Volcanic Eruption
Show Answer
Correct Answer: D [Volcanic Eruption]
Notes:
Temperature increases when we go deep into the earth. Therefore scientist depends on some sources to study interior of the earth. Based on the nature of source they are divided into two types:
Direct sources- Surface rocks, volcanic eruption forms etc.
Indirect sources- Magnetic field, gravitation, seismic activity, meteors etc.
3. On which among the following dates Earth may be on Perihelion (Closest to Sun)?

Show Answer
Correct Answer: A [January 4]
Notes:
The point in the orbit where the planet is closest to the Sun is called “perihelion”. The point where the planet is farthest from the Sun is called “aphelion”.
4. Sun shines exactly over equator for how many times a year?
[A] Once in a year
[B] twice in a year
[C] four times a year
[D] 12 times in a year
Show Answer
Correct Answer: B [twice in a year]
Notes:
The sunshines generally occur over the equator twice a year. During the summer equinox and autumn equinox.
5. The size, mass & density of which of the planets is very near to those of Earth ?
[A] Venus
[B] Mercury
[C] Jupiter
[D] Saturn
Show Answer
Correct Answer: A [Venus]
Notes:
The size, mass & density of Venus is very close to that of earth. Venus is the second planet from the Sun. It is the second-brightest natural object in the night sky after the Moon.
6. Which of the following is the reason behind the seasons on the Earth? (UPSC Prelims 1991)
[A] The elliptical orbit of the Earth
[B] Alteration/change in the speed of revolution of the Earth
[C] Inclination of the Earth on its axis of rotation
[D] Differences in the amount of energy received from the Sun
Show Answer
Correct Answer: C [Inclination of the Earth on its axis of rotation]
Notes:
The seasons are caused by the tilt of the Earth’s rotational axis away or toward the sun as it travels through its year-long path around the sun. The Earth has a tilt of 23.5 degrees relative to the “ecliptic plane”.
7. Which of the following archipelago contributed to the inception of the Darwin’s Theory of Evolution?

Show Answer
Correct Answer: D [Galapagos Islands]
Notes:
The Galapagos Islands are distributed on either side of the equator in the Pacific Ocean & are the home for large number of endemic species. They were studied by Charles Darwin & it led to the inception of Darwin’s theory of Evolution by means of natural selection.
