Amazing Sahara desert

The Sahara Desert is the largest hot desert in the world, and the third largest overall after the Antarctica and the Arctic. The Sahara Desert covers an incredible 9.2 million km², which is almost the same size as China, and a total of 8% of the earth's land area. 

The enormous desert spans 11 countries: Algeria, Chad, Egypt, Libya, Mali, Mauritania, Morocco, Niger, Western Sahara, Sudan and Tunisia. The Sahara desert has a variety of land features, but is most famous for the sand dune fields that are often depicted in movies.

 Purely in terms of size, the Antarctic Desert is the largest desert on the planet, measuring a total of 13.8 million square kilometers (or 5,500,000 square miles). Antarctica is not only the most isolated continent on Earth but also the coldest.

 The Sahara Desert covers an area of northern Africa larger than the lower 48 United States. And it's growing even bigger. ... So some areas that were once semi-arid grassland have become desert.

 As well as being the largest and driest desert, the Antarctic Ice Sheet, which occupies around 99% of the continent, is also the coldest desert on Earth.

 The population of the Sahara is just two million. People who live in the Sahara are predominantly nomads, who move from place to place depending on the seasons. Whilst others live in permanent communities near water sources. The Sahara Desert really is an intriguing and beautiful place, waiting to be explored.

 The depth of sand in ergs varies widely around the world, ranging from only a few centimeters deep in the Selima Sand Sheet of Southern Egypt, to approximately 1 m (3.3 ft) in the Simpson Desert, and 21–43 m (69–141 ft) in the Sahara.
