Question
Consider the statements below regarding the sub-tropical deserts in the world :

  1. These deserts are located along the West coast of the continents.

  2. These are under the influence of subtropical high-pressure belts.

  3. These are also influenced by the movement of cold oceanic current along the coast.


Which of the above statements is/are correct?
Options:
A .  1 and 2
B .  1, 2 and 3
C .  1 and 3
D .  2 and 3
Answer: Option D
Answer: (d)
They are located in the rain shadow zone of the world due to the movement of the trade winds. They are also under the influence of the subtropical high-pressure belts of the world.
This belt creates anti-cyclonic conditions and hence also rainfall. The cold current along the coast is responsible for the rainfall over the ocean.
It is because, when the moisture-laden wind comes in contact with the cold current, they shed their moisture over the ocean due to low temperature.
Hence, no rainfall over the coast of the continent.
Hence, the above statements are correct.
