Sahara Desert: Hottest Desert in the World
The Sahara Desert is the largest and hottest desert in the world. Temperatures can reach as high as 57.7 degrees Celsius. It is spread over more than 9,000,000 square km and is as big as the United States. Scientists, however, say this desert expands and shrinks over time. In fact, records show that the Sahara Desert grows southward by about 48 km each year.
The desert starts at the Red Sea, spreads across the Mediterranean, and even over to the Atlantic Ocean. It touches 12 African nations including Egypt, Chad, Algeria, Eritrea, Libya, Morocco, Niger, Mauritania, Mali, Sudan, Western Sahara, and Tunisia.
Life in the Sahara Desert can be very difficult to sustain due to its climate. It receives less than three inches of rain every year.
The typical animals found here include domestic camels and goats. It is common to see scorpions, monitor lizards, sand vipers, wild dogs, ostriches, cheetahs and more.
