  非洲广泛分布着由地质作用所形成的大断裂,最著名的是东非大裂谷,又称非洲-阿拉伯大裂谷、大裂谷或裂谷。它是地球表面最大裂谷的一部分,也是世界上最长的裂谷带。

  

世界上最长的裂谷带

 

  从约旦向南延伸,穿过非洲,止于莫桑比克。总长6400公里,平均宽度48至64公里。北段有约旦河、死海和亚喀巴湾。向南沿红海进入埃塞俄比亚的达纳基勒洼地,然后进入肯尼亚的鲁道夫湖、奈瓦沙湖和马加迪湖。坦桑尼亚境内一段东缘因受侵蚀已不太明显。

  裂谷后向南经希雷谷到达莫桑比克贝拉附近的印度洋沿岸。西面一岔裂谷从尼亚萨湖北端呈弧形延伸,经过鲁夸湖、坦噶尼喀湖(世界第二深湖,1463米)、基伍湖、爱德华湖和艾伯特湖。裂谷湖泊多深而似峡湾,有些湖底大大低于海平面。裂谷附近高原一般向上朝裂谷倾斜,至谷底平均落差600至900米,有些地段达2700米以上。据推测,裂谷形成于上新世和更新世,一些地段同时伴随有大规模火山活动,因而形成乞力马扎罗(5895米)和肯尼亚(5199米)等山峰。

  Africa widely distributed large fracture formed by geological processes, the mostfamous is the Great Rift Valley, also known as Africa - Arabia rift, rift or rift. It is a part of the earth's surface the maximum rift, is also the world's longest rift belt.

  The world's longest Rift Valley

  Extending from the south across the Jordan, Africa, ending in Mozambique. The total length of 6400 kilometers, with an average width of 48 km to 64 km. North of Jordan,the dead sea and the Gulf of Aqaba. South along the Red Sea into Ethiopia's DanaKeeler depression, and then into Kenya Lake Rudolf, Shahu and lake Magadiconstrain. The territory of Tanzania section of the eastern margin of eroded by is nottoo obvious.

  The world's longest Rift Valley

  After a rift southwards through the shire Valley Bella arrived in Mozambique near Indiaocean. The west fork rift from Lake Nyasa North curved extension, after the lake Rukwa, Lake Tanganyika (the world's second deep lake, 1463 meters), Lake Kivu and lake Edward and lake Albert. Many deep rift lakes like Lake and Fjord, someconsiderably below sea level. The rift valley near the plateau sloped upward toward the rift valley, to the average height of 600 to 900 meters, some areas more than 2700 meters. It is assumed that the rift formed in the Pliocene and Pleistocene, some lots also accompanied by massive volcanic activity, thus forming the Kilimanjaro (5895 meters) and Kenya (5199 meters) and other peaks.
