How are dry valleys formed?

Answer 1

when melted water from the ice age erodes a valley but without the constant flow of water from the melting ice it dries up as there is not enough water to keep flowing through it, so it dries up but leaves the valley it has cut into the landscape. when melted water from the ice age erodes a valley but without the constant flow of water from the melting ice it dries up as there is not enough water to keep flowing through it, so it dries up but leaves the valley it has cut into the landscape.

Answer 2

Dry valleys are formed through a combination of geological processes such as erosion, tectonic activity, and glaciation. These valleys often lack water due to limited precipitation or impermeable underlying bedrock that prevents water from flowing through. The dry conditions in these valleys inhibit the growth of vegetation, contributing to their desolate and arid appearance.
