Answer 2

Since the options have not been given, I am giving an assumed answer.

Gorges are small forms of valleys which are formed by the Earth's tectonic activity. It, in turn, gives a vertical uplift to the landscape.

The Gorges can be typically 2 types - Canyons or Valleys.

The Valleys are formed in places where there are a lot of water bodies like the rivers.

As it is mentioned as arid regions in the question, it could be regions which do not have much of water. So, it must be the canyons. The Canyons are valleys that are deep, steep-walled and V-shaped. Some of the famous and largest canyons are pieces of land in the arid or semiarid regions that are cut through by the swift water streams which are fed by the rain or the melting snow.
