Sahara Desert

The Sahara Desert is the world's largest desert area. The word Sahara is coming from the Arabian safaris meaning the desert. It extends from the Atlantic side of Africa to the Red Sea and consists of countries such as Morocco, Algeria, Tunisia, Libya, Egypt, Mauritania, Mali, Niger, Chad, Sudan. It is about 5,200 miles long. Overall, the Sahara Desert covers an area of ​​3500,000 square miles. The geographical position of the desert varies. In the west, the Sahara is a rock with different elevations.

An interesting fact that is not well known is that the Sahara is often considered the largest desert in the world, and the Sahara desert is actually the third largest desert. According to the definition, the desert is an area with less than 10 inches rainfall per year. As a result, Antarctica and the Arctic Circle are both qualified to become deserts and are larger than the Sahara Desert. However, the Sahara Desert is the largest hot desert. The Sahara desert is not necessarily a desert. After the last glacial age the landscape was as dry as barren today and it was barren. However, about 10, 500 years ago, due to the rapid rainfall of the monsoon, the living desert changed into a livable prairie. Human beings and animals living in the Nile River Valley can be expanded to the prairie as radioactive carbon and human and animal body are confirmed by scientists. During the next few hundred years the rain continued, the human settlement grew, and even domesticated livestock like goats and sheep were introduced.

Because the Sahara Desert occupies nearly 10% of the African continent, the Sahara Desert is often regarded as the world's largest desert. However, as it is the hottest desert in the world, this is not entirely true. According to the definition of the desert as an area of ​​desert annual rainfall less than 10 inches (250 mm), the world's largest desert is actually Antarctica. The Sahara covers some African countries, including Algeria, Chad, Egypt, Libya, Mali, Mauritania, Morocco, Niger, Sudan and Tunisia. The majority of the Sahara Desert has not been developed yet and the terrain is also diverse. Most of that landscape forms winds over time, such as sand dunes, sandy seas called Elg, barren stone plateaus, gravel plains, dry valleys, and salt plains. Approximately 25% of the desert is a sand dune, some of which are over 500 feet (152 meters) high.
