The Sahara Desert is basically the main environment in which the Tuareg live and travel around. It is the world's largest hot and driest desert and covers around 10% of the total continent of Africa. In the southern part of the desert there is a place called Sahel, which marks the end of the desert landscape, gradually transforming it into a semi-arid tropical savannah. A savannah is a grassy plain, which is very dry and also includes some tropical and sub-tropical regions, all having very few trees. It basically covers several parts of the various African nations including Algeria, Chad, Egypt (half), Libya, Mauritiana, Morocco, Niger and a couple more. Practically the landscape of the Sahara Desert is undeveloped. This landscape was gradually formed by strong wind and as a result features many sand dunes, sand seas, which are known as ergs, empty stone plateaus, gravel plains, some dry valleys and some salt flats. Around 1/4 of the desert is mainly comprised of a plethora of sand dunes that are also different shapes. Some of these big sand dunes reach over 150m in height. There are indeed several mountain ranges in the Sahara, some of which are even volcanic! The highest peak that is found in this mountain range is called Emi Koussi, which is a shield volcano that reaches up to nearly 3,500m. It is an aspect of the Tibetsi range, which is located in Northern Chad.
Most of the water found in the Sahara Desert nowadays is in the form of seasonal and intermittent streams. Intermittent streams are streams that
carry water for a considerable portion of time, but which never stop to flow occasionally and seasonally because bad seepage can exceed the available water supply. The elevation of the Sahara Desert is approximately 2997 feet. The average temperature of the Sahara is over 30°C. The mean temperature in summer is also 30°C and in winter the mean temperature is around 13°C .These are only the average temperatures as the main temperature range is more than 50°C. Since the Sahara Desert is known as the driest place on Earth, it receives less than 10 inches of rainfall or precipitation. The Sahara Desert has actually received snow, only once on the 8th of February,1979. It occurred mainly in Southern Algeria, with the addition of a snow storm in Ghardaïa, creating traffic. The snow was gone within hours, but the high mountain ranges in the Sahara Desert can receive snow on a more regular basis.
