The Sahara Desert is the largest desert in the world. It is about 9,000,000 square kilometres in size. This is almost the size of America or China. The desert covers eleven countries in the north of Africa.
The Nile runs through the Sahara Desert all year round. But there are also other rivers running through it seasonally. The geography of the desert includes huge sand dunes and dune fields. Some of the sand dunes are so huge that they can even be over 152 metres high. But there are also other amazing landforms in different parts of the desert.
It is very hot and dry in the Sahara Desert. The temperature there is usually 30℃. However, during the hottest months, the temperature can go over 50℃. Because of the high temperatures and poor conditions of the desert, only a few plants live here, just about 500 kinds. They also play a role in the number of animals. In the driest part of the desert, there are only 70 different kinds of animals.
Today the Sahara's population is around four million. They move from place to place through the desert. Because of this there are many different cultures and languages in this area.
