Question

Why most of the world deserts are located in the western margins of continents in the subtropics?

Answer 1

✔Most of the worlds deserts are located in the western margins of continents in the subtropics because the prevailing winds in the tropics are tropical easterly winds. The tropical easterly winds become dry by the time they reach the western margins of the continents and so they bring no rainfall.

Answer 2

When the moisture laden trade wind flows from east to west shed their moisture on the eastern part and by the time they reach the western margin, they become dry. These dry winds make the soil more and this led to the formation of the desert.
