When continental plates pull apart at a divergent boundary on land in what kind of form?

When continental plates pull apart at a divergent boundary on land, they create a rift valley. This occurs as the crust thins and fractures, resulting in the formation of deep valleys surrounded by high land. Over time, volcanic activity and sediment deposition may also occur in these rift areas, leading to further geological changes. An example of this process is seen in the East African Rift.
