The Sahara Desert covers much of North Africa. It stretches from the Red Sea in the east to the Atlantic Ocean in the west and runs southward to the Sahel savannah. Its terrain includes mountains, rocky plateaus, gravelly plains and sand dunes. Fertile areas, called oases, radiate throughout this barren landscape. The Sahara has a hot, dry climate with little precipitation. It is hot during the day but cool at night. A variety of plants that Saharan inhabitants use for many purposes thrive in this desert environment.
