It's as big as the continental United States, but covered in sand. If you like to dig your feet in the sand, then the Sahara Desert is the place for you. Watch out though - it's hot! Temperatures range from 122 F to below freezing in the winter. Sand dunes can reach over 189 meters tall or be flat for miles and miles.
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.Rainfall can range from twice in one week to an extreme of no rainfall over the next three years. Oases are scattered throughout this desert.ife in the Sahara Desert can be very difficult to sustain due to its climate. It receives less than three inches of rain every year.
