Sahara desert is the third highest desert on the world.......
it is too hotter than other desert...
it is the largest desert on the african continent.the southern border of the sahara is marked by a band of semiarid savvana called sahel. people lived on the edge of desert thousand years ago...... sahara was then much wetter place than today. then,due to climate change, savvanah change into the sandy desert as we know now...!
