非洲大陆,总面积达二千九百多万平方公里,位于东半球的西南部,屹立在印度洋和大西洋之间。它是一个类似三角形的大陆。你能想到非洲大陆正在瓦解之中吗?然而这确是事实,非洲的瓦解在于在高高翘起的东部高原的脊部,有一个狭长的陷落地带,即东非大裂谷。东非大裂谷是非洲大陆上的一条伤疤。这个大裂谷是由一组巨大的断层组成的。由于沿着断层的两侧长期以来不断地上升,中间地带就相对沉陷了下去,久而久之也就形成了一个很长、很深的地带,接受着新的沉积。东非大裂谷从南往北贯穿了整个非洲东部, The African continent, with a total area of ​​over 29 million square kilometers, lies in the southwestern part of the Eastern Hemisphere and stands between the Indian Ocean and the Atlantic Ocean. It is a triangle-like continent. Can you think of the continent being broken down? Yet it is a fact that the collapse of Africa lies in the ridges of the soaring East Plateau with a long narrow fall, the Great Rift Valley. The Great Rift Valley is a scar on the continent. The Great Rift Valley is made up of a huge group of faults. Since the two sides of the fault have been rising continuously for a long period of time, the middle ground has been relatively subsided, and as time passes it has formed a very long and deep ground that is receiving new sediments. The Great Rift Valley runs through the entire east of Africa from south to north,
