But, at night most of the heat in the sand quickly radiates into the air and there is no sunlight to reheat it, leaving the sand and its surroundings colder than before.

Why did the Sahara dry up? 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 original source of the sand was the large mountain ranges that still exist in the central part of the Sahara.

Why North Africa is a desert?

The answer lies in the climate of the Arctic and northern high latitudes. … This rapid transition 5,500 years ago stems from a cooling of northern high latitudes. The cooler temperatures in the north weakened the high altitude Tropical Easterly Jet, which consistently brought moisture into northern Africa.

Was the Sahara desert once an ocean? The Sahara Desert was once underwater, in contrast to its present-day arid environment.
