| Consider the following statements 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 sub-tropical high pressure belts. |
| 3. These are also influenced by the movement of cold oceanic current along the coast. |
| Which of the statements given above are correct? |
A) 1 and 3
B) 1 and 3
C) 1 and 2
D) All of these
Correct Answer: D
Solution :
[d] The sub-tropical deserts in the world are lying along the west coast of the world's continents. 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 sub-tropical high pressure belts of the world. These belt create the anti-cyclonic conditions and hence rainfall. The old current along the coast is responsible for the rainfall over the ocean. It is because, when moisture laden wind come in contact with the cold current, they shed their moisture over the ocean due to low temperature. Hence, no rainfall over the coast of continent. So, all the statements are correct.
