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.
South Africa's weather and climate. The country is bordered on the west by the Atlantic Ocean and on the east by the Indian Ocean; their waters meet at Cape Agulhas, at the southern-most tip of the continent. South Africa is famous for its sunshine.It's a relatively dry country, with an average annual rainfall of about 464mm; the world average is about 860mm. While Western Cape gets most of its rainfall in winter, the rest of the country is generally a summer-rainfall region.emperatures in South Africa tend to be lower than in other countries at similar latitudes such as Australia mainly because of its greater elevation above sea level. South Africa's coastal regions have the warmest winter temperatures in the country.
