The East African Rift Valley is a prominent example of rift valleys on Earth, running through countries like Ethiopia, Kenya, and Tanzania. Another well-known rift valley is the Great Rift Valley in Asia, which extends from Syria to Mozambique. These rift valleys are formed by tectonic plate movements that create deep valleys and high mountains.

When the earth's crust splits apart and a ravine is formed, it is called a rift valley. Rift valleys are created by the stretching and thinning of the Earth's crust, often associated with tectonic plate movements or volcanic activity. Examples of rift valleys include the East African Rift and the Rhine Valley in Europe.
