What was the formation process of the Great Rift Valley?

It is just that, a rift in the earth's crust related to the spreading centers and rifting faults mapped in the oceans of the world. The rift is in the process of tearing Africa apart. Earlier, similar rifting tore off what later became India and Madagascar etc. read more

According to geologists, the Great Rift Valley was formed by huge subterranean forces that tore the earth's crust apart, causing chunks of the crust to sink into the earth. The process is called "rifting" and is still going on today. read more

Very few active rift valleys are found on continental lithosphere. The East African Rift, the Baikal Rift Valley, the West Antarctic Rift, and the Rio Grande Rift are Earth’s major active continental rift valleys. The East African Rift is part of the “Great Rift Valley” system discussed below. read more

As the walls of a rift valley are pulled apart, the floor of the valley tends to sink. If this subsidence happens faster than erosion from the walls can fill it in with sediment, the floor of the valley continues to fall relative to the surrounding terrain. This process is at work in both the Baikal rift and the East African rift. read more
