A rift valley is the reverse of a fault block mountain. Rift valleys are linear shaped low lands and divergent plate boundaries.
A rift valley is a linear lowland between highlands or mountain ranges created by the action of a geologic fault or rift zone. It often forms where tectonic plates are moving apart, leading to the stretching and thinning of the Earth's crust, resulting in a depressed landscape. Rift valleys can be found on land or beneath the ocean.
An example of a normal fault is the Great Rift Valley of Africa.
