Why did the Sahara become a desert?
The rise in solar radiation amplified the African monsoon, a seasonal wind shift over the region caused by temperature differences between the land and ocean. The increased heat over the Sahara created a low pressure system that ushered moisture from the Atlantic Ocean into the barren desert.
Was Africa always a desert?

Why are deserts found in western sides?
The trade winds prevail in the lower portion of the earth’s atmosphere, in the lower section of the troposphere. These winds become dry when they reach the western sides of the continents, and hence don’t bring any rain with them. As these regions become devoid of moisture, deserts are formed.
Why are most of the deserts located in the western side of the continent?
Answer: 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.
Why do deserts exist?
Deserts are formed by weathering processes as large variations in temperature between day and night put strains on the rocks, which consequently break in pieces. … Rocks are smoothed down, and the wind sorts sand into uniform deposits. The grains end up as level sheets of sand or are piled high in billowing sand dunes.
