6. 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.
7. Deserts such as the Sahara are generally found between 20° and 30° latitudes in the western parts of the continents. This is because these regions? (UPSC Prelims 1992)
