Ch. 13 pdf: Africa
by Cole Ison
Africa is the second largest continent on the world. An immense desert, the Sahara, stretches across most of North Africa. Along the northwestern edge of the Sahara lie the Atlas Mountains. In eastern Africa, mountains extend alongside great rifts. These rifts are long, deep valleys formed by the movement of the earth's crust.
Like Ghana, Mali lay along the upper Niger River. This areas fertile soil helped Mali grow. Mali's location on the Niger River also allowed its people to control trade along the river. As a result, the empire grew rich and powerful. According to legend, Mali's rise to power began under a ruler named Sundiata.
