2. Which of the following is the value of Hubble constant?
[A] 73 kilometers per second per mega parsec
[B] 75 kilometers per second per mega parsec
[C] 77 kilometers per second per mega parsec
[D] 69 kilometers per second per mega parsec
Show Answer
Correct Answer: A [73 kilometers per second per mega parsec]
Notes:
The expansion rate of the universe is called the Hubble Constant. Currently the best measured value of the Hubble Constant is about 73 kilometers per second per mega parsec.
3. Who among the following proposed steady state theory with respect to universe?
[A] Einstein
[B] Laplace
[C] Newton
[D] Hoyle
Show Answer
Correct Answer: D [Hoyle]
Notes:
Hoyle’s concept of steady state is opposite to Big Bang theory. It considered the universe to be roughly the same at any point of time
4. At which among the following places, the aeration zone is located in Earth’s Lithosphere?
[A] Above earth surface
[B] Below earth surface & above Water Table
[C] Below Earth’s surface and parallel to water table
[D] Below earth’s surface and below water table
Show Answer
Correct Answer: B [Below earth surface & above Water Table]
Notes:
The zone of aeration is the region between the earth’s surface and the water table. The main components of this region are the soil and rocks.
5. On around which among the following dates, Earth is at it’s farthest from the Sun?
[A] January 4
[B] July 4
[C] June 21
[D] December 22
Show Answer
Correct Answer: B [July 4]
Notes:
Perihelion is the point when Earth is closest to Sun and it occurs around 3rd January. The distance is 147.5 million kms. Aphelion is the point when Earth is farthest from the Sun and it occurs on July 4. The distance is 152.5 million Kms.
6. Apart from Saturn, which of the following planets have planetary ring systems of their own?
[A] Jupiter only
[B] Jupiter, Uranus & Neptune
[C] Jupiter & Uranus
[D] Jupiter & Neptune
Show Answer
Correct Answer: B [Jupiter, Uranus & Neptune]

7. Amazon river is the largest river in the world by volume and has the largest drainage basin in the world. This accounts for approximately what fraction of the world’s total river flow?
[A] 10%
[B] 20%
[C] 30%
[D] 40%
Show Answer
Correct Answer: B [20%]
Notes:
Amazon river is the largest river in the world by volume and has the largest drainage basin in the world. This accounts for approximately 20% of the world’s total river flow. The Amazon River flows in South America.
8. If the earth had no satellite of its own i.e., the moon, which of the following phenomena will not occur ?
[A] Neap tides
[B] Ocean currents
[C] Spring tides
[D] Tides
Show Answer
Correct Answer: C [ Spring tides]
Notes:
The moon has a significant impact on tides, due to the gravitational attraction of the moon on the Earth’s water. This effect is magnified when the moon’s gravitational attraction aligns with the gravitational pull of the sun. This produces the highest high tides and lowest low tides, known as spring tides. When the pull of the moon and the sun are perpendicular to each other, the lowest high tides and highest low tides, collectively termed neap tides, are produced. While ocean currents are primarily affected by winds and the Coriolis force, tides can have a large impact on currents near the coasts.
9. In geographical context, what is Hamada?
[A] a type of desert landscape
[B] a desert counterpart of the delta
[C] a semi-circular steep sided depression formed through glacial erosion
[D] land-forms created by simultaneous erosion and deposition in a stream channel
Show Answer
Correct Answer: A [a type of desert landscape]
Notes:
Hamada is a type of desert landscape consisting of high, largely barren, hard rocky plateaus with very little sand because this has been removed by deflation. Hamadas are produced by the wind removing the fine products of weathering: an aeolian process known as deflation.
10. Which of the following is the reason behind the different seasons to occur?
[A] Sun is moving around the earth
[B] Of revolution of the earth around the sun on its orbit
[C] Tilt of Earth’s axis
[D] All of the above
Show Answer
Correct Answer: C [Tilt of Earth’s axis]
Notes:
The four seasons happen because of the tilt of the Earth’s axis. At different times of the year, the sun’s rays hit different parts of the globe more directly. The angle of the Earth’s axis tilts the Northern Hemisphere towards the sun during the summer.
