What could be the main reasons for the formation of African and Eurasian desert belt? 1) It is located in the sub-tropical high pressure cells. 2) It is under the influence of warm ocean currents. Which of the statements given above is/are correct in this context?

Question

Correct Answer: 1 only. African and Eurasian desert belt lies in vicinity of cold currents having desiccating effect on air, so with this we see that statement 2 is incorrect. Normally it is seen that deserts are mostly located around 20-30 ° north and south of Equator along Tropics of Cancer and Capricorn. The hot air at equator rises and spreads north and south before cooling which further gets condense and tends to release moisture over tropical zones creating equatorial zone of low atmospheric pressure. Two tropical zones are at high pressure close to the poles which are 2 low cooler pressure belts. When denser air sinks to 2 subtropical high pressure belts, it creates a wind which is hot without moisture that normally appears from Sahara, hence statement 1 is correct, so the best option is a.
