The effect of heatâthe random motion of the atomsâis much stronger than the effect of gravity. Now let's concentrate on a larger group of atoms. Imagine, for example, 50, 100, 1000, even a million atoms, each gravitationally pulling on all the others. The force of gravity is now stronger than before.
Great parts of North Africa and Southern Africa as well as the whole Horn of Africa mainly have a hot desert climate, or a hot semi-arid climate for the wetter locations. The Sahara Desert at the north is the largest hot desert in the world and is one of the hottest, driest and sunniest places on Earth.nly the northernmost and the southernmost fringes of the continent have a Mediterranean climate because they aren't located under the tropics. Because of this geographical situation, Africa is a hot continent as the solar radiation intensity is always high.
There are the hot and dry desert, the semiarid desert, the coastal desert, and the cold desert. The Hot Desert. This desert's average temperature ranges from 64 to 77 degrees Fahrenheit. The extreme temperature is 110.3 to 120 degrees Fahrenheit.
