1. Who among the following formulated Nebular theory?
[A] Laplace
[B] Newton
[C] Kepler
[D] Ptolemy
Show Answer
Correct Answer: A [Laplace]
Notes:
Nebular theory was formulated by Laplace which describes the formation of the Sun and solar system. Laplace along with his colleague John Michel, introduced the idea of a “dark star,” which later came to be called as black hole.
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. How much of longitude account for one hour?
[A] 10 degree
[B] 15 degree
[C] 20 degree
[D] 25 degree
Show Answer
Correct Answer: B [15 degree]
Notes:
1 hour is equal to 15 degress. 360 degrees is equal to 24 hours and when we divide 360 by 24 we get each hour equal to 15 degree.
4. Appleton layer is a part of _______?
[A] Stratosphere
[B] Mesosphere
[C] Ionosphere
[D] Exosphere
Show Answer
Correct Answer: C [Ionosphere]
Notes:
Appleton layer is part of ionosphere. It is the highest region of the ionosphere. It is from 90 to 600 miles from sea level. It is which contains the highest concentration of free electrons and is most useful for long-range radio transmission.
5. Which among the following continent is with the highest mean elevation in the world?
[A] North America
[B] Asia
[C] South America
[D] Antarctica

7. With reference to the temperature of the oceans, it has been noted that there is a very low decrease of temperature with increasing latitudes towards north in comparison to the southern Atlantic. What could be the possible reason for this?
[A] Gulf stream, a cold current brings down the temperature of southern Atlantic
[B] Gulf stream, a warm current brings up the temperature of northern Atlantic
[C] North Atlantic has more underwater volcanoes
[D] The mid Oceanic ridge is more prominent in north Atlantic
Show Answer
Correct Answer: B [Gulf stream, a warm current brings up the temperature of northern Atlantic]
Notes:
In Northern Atlantic, there is a very low decrease of temperature with increasing latitudes towards north. This is because of the Gulf Stream currents which are warm currents. However, in southern Atlantic, the decrease of temperature with increasing latitude is more pronounced.
8. Why is there a severe difference in the climates of Northern and Southern Hemisphere?
[A] Due to rotation of the earth around its axis
[B] Due to revolution of the earth around the sun of its orbit
[C] Both of the above
[D] None of the above
Show Answer
Correct Answer: C [Both of the above]
Notes:
There are several reasons for the difference in the climates of Northern and southern hemisphere. These are rotation of the earth around its axis and the revolution of the earth around the sun of its orbit.
The biggest factor in differences in the climate in the Northern and Southern Hemispheres has to do with the distribution of land vs. ocean. The Northern Hemisphere has much more of Earth’s land masses, while the Southern Hemisphere has a larger fraction of ocean.
