Question

Accepted Answer

Both (A) and (R) are true and (R) is the correct explanation of (A). The major hot deserts of the world are located on the western coasts of continents between latitudes 15º and 30º N and S. They include the Sahara Desert, the largest single stretch of desert, The Great Australian Desert covers almost half of the continent. The reason for existence of such desert is because of: → Trade winds blow from east to west and hence loose moisture/humidity till they reach on the western continental margins. → The orbital movement of cyclones are also from east to west and they become weak in the west of continents.
