Sink hole is a phenomenon of topography.

Options

A. Plain
B. Desert
C. Tundra
D. Karst

Answer

D

Explanation

The underground water of Karst topography carves our impressive channels and caves that are susceptible to collapse from the surface. When enough limestone is eroded from underground, a sinkhole (also called a doline) may develop. Sinkholes are depresstions that form when a portion the lithosphere below is eroded away.
