11. Sunrise in Eastern Arunachal Pradesh would be about how many hours before the sunrise in Western Gujarat?

Correct Answer: (b) Two hours
Solution:India extends approximately between longitudes 68º7' E (Gujarat) and 97º25' E (Arunachal Pradesh). This is a longitudinal spread of nearly 30º. Since the Earth rotates 360º in 24 hours (15º per hour), a 30 difference results in a time gap of approximately 2 hours. Consequently, the sun rises two hours earlier in the east than in the west.

12. Consider the following States of India in terms of percentage of forest area in relation to the total area of the State.

4. Andhra Pradesh
Which one of the following is the correct descending order?

Correct Answer: (c) 3-2-1-4
Solution:

Based on the India State of Forest Report (ISFR), the ranking for these specific states by percentage of geographical area is:

  1. Kerala: ~54% (Highest among these four)

  2. Odisha: ~33%

  3. Karnataka: ~20%

  4. Andhra Pradesh: ~18% (Lowest among these four)

3. Atmospheric instability.
The above mentioned characteristics are associate with which one of the following cycles of its development?

Correct Answer: (c) Full maturity
Solution:The conditions mentioned—sea surface temperature 26.5ºC, high humidity in the lower to middle troposphere, and atmospheric instability—are the pre-requisites or the formative conditions necessary for a tropical cyclone to trigger and develop.
