Why is Sahara so dry?

The end of the glacial period brought more rain to the Sahara, from about 8000 BCE to 6000 BCE, perhaps because of low pressure areas over the collapsing ice sheets to the north. Once the ice sheets were gone, the northern Sahara dried out. … The Sahara is now as dry as it was about 13,000 years ago.

Why does the Sahara not get rain?

Hot, moist air rises into the atmosphere near the Equator. … As it approaches the tropics, the air descends and warms up again. The descending air hinders the formation of clouds, so very little rain falls on the land below. The world’s largest hot desert, the Sahara, is a subtropical desert in northern Africa.

Thus, warm and hot climates prevail all over Africa but the northern part is the most marked part by aridity and high temperatures.

Why is half of Africa desert?

The answer lies in the climate of the Arctic and northern high latitudes. … However, around 5,500 years ago there was a sudden shift in climate in northern Africa leading to rapid acidification of the area. What was once a tropical, wet, and thriving environment suddenly turned into the desolate desert we see today.

Why did the Sahara turn into 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.

Why does Africa have no water?

The main causes of water scarcity in Africa are physical and economic scarcity, rapid population growth, and climate change. Water scarcity is the lack of fresh water resources to meet the standard water demand.
