Question

Which of the following statements correctly describes the formation of hot deserts?

1. Large hot deserts like the Sahara and Arabian deserts are found in the trade wind belt near sub-tropical high-pressure belts.
2. These deserts are located under the ascending limb of the Hadley Cell, leading to increased condensation and precipitation.
3. The descending limb of the Hadley Cell, which causes air to warm adiabatically and inhibits precipitation, is a key factor in their formation.
4. Hot deserts are primarily formed due to extreme volcanic activity.

• A. i
• B. iv മാത്രം
• C. ii, iv
• D. i, iii

Answer 1

Answer:

D. i, iii

• The largest hot deserts, like the Sahara and Arabian deserts, are located in the trade wind belt near the sub-tropical high pressure belts in both the hemispheres.

• These are places located under the descending limb of the Hadley Cell that dominates the at-mospheric circulation in tropical areas.

• As the air subsides, it warms adiabatically, in-hibiting condensation and precipitation.

• Some deserts are located on the leeward side of mountains and the rain shadow effect is responsible for their formation.
