1. Which of the following statements correctly explains the temperature difference between the Bay of Bengal and the Arabian Sea?

a) The Bay of Bengal is semi-enclosed and landlocked, so it retains warm water around 29–30°C throughout the year.

b) The Arabian Sea is enclosed and remains warmer due to less wind activity.

c) Both seas have the same temperature due to equal sunlight.

d) The Bay of Bengal remains cooler due to high evaporation.


Answer: a) The Bay of Bengal is semi-enclosed and landlocked, so it retains warm water around 29–30°C throughout the year.

The Bay of Bengal stays warmer (about 29–30°C year-round) because it is semi-enclosed and landlocked, which limits water exchange and traps heat.

The Arabian Sea, on the other hand, is cooler because stronger winds and higher evaporation reduce surface temperature.

3. Which region of India accounts for about 42 % landslide hazard zone?

Answer. b) Northeastern Hills


Nearly 13% of India’s land area (0.42 million sq. km) is landslide-prone, as per the Geological Survey of India (GSI).

High-risk zones include the Himalayas, the Northeastern hills, the Western Ghats, Nilgiris, and Eastern Ghats.
