There signs that a huge part of East Africa is to break away from the African continent. Geologists (people who the Earth and its land and rocks) a deep crack that along a large part of Zambia. The crack is called a rift. It is a major fault in the rock that Earth's surface. Geologist Mike Daly of the University of Oxford is studying Zambia's Kafue Rift. He there is activity in the rift that a giant piece of land is breaking away. He wrote: "There is evidence that the fault boundary of the Kafue Rift is active and therefore the Southwest African Rift Zone too." He warned that this "may an early indication of the break-up of sub-Saharan Africa".

The land on Earth constantly moving. Three hundred million years ago, there just one huge supercontinent. It was Pangea. Over millions of years, Pangea up. Giant areas of land slowly across the oceans to the continents we know today. This movement is called continental drift. Rifts are one reason why land masses apart. The Kafue Rift in Zambia is part of a 2,500-kilometre-long rift zone stretching from Tanzania to Namibia. The rift is at a rate of about 4.7 mm per year. At this rate, it will millions of years for Africa to split in two. Scientists believe that in 200 million years from now, there could just one supercontinent again.
