How does rain affect the desert?

When rainfall does occur in the desert, it can result in startling changes in the local conditions. Torrential storms can flood dry riverbeds and wadis, producing flash floods in areas that may not have seen moisture in months. These, in turn, fuel responses in many desert-adapted animals.

How did deserts get so dry?

Rainforest and deserts are wet and dry due to the cycle of the air. This warm, dry air can hold a lot of water, so the air starts to suck up what little water is around. At 30 to 50 degrees north and south of the equator, this falling air makes dry air drier. It also turns the land below it into a desert.

How cold does the Sahara get?

Option C: Africa mainly lies within the equatorial zone between the Tropic of Cancer and the Tropic of Capricorn. Africa is a hot continent as the heat of the sun is always strong there. Thus, warm and hot climates prevail all over Africa but the northern part is the most marked part by aridity and high temperatures.

What is the average rainfall for the Sahara Desert region?

What desert has the least rain?

The Atacama desert in the Andes mountains of South America is so dry it experiences less than .01 cm of rain per year on average, and some areas can go years without any rain at all. Yet even these arid places have some water, and will support some life.
