Are yardangs constructive or destructive

Answer 1

Yardangs are generally considered to be destructive landforms, as they are shaped by erosional processes, primarily wind erosion. These streamlined ridges are formed when wind removes loose material from one side, often leading to the erosion of softer rock or sediment. While they can create unique landscapes, their formation indicates the removal and alteration of existing geological features rather than the addition of new material.
