question 5 of 10
which is one way that sinkholes can form?
a. rivers overflow during a storm and wash away nearby land.
b. groundwater dissolves the limestone and other rocks in the ground.
c. rainwater flows away from a depression in the ground.
d. tornadoes touch down and destroy trees and brush.

Explanation:

Sinkholes form when soluble rocks like limestone are dissolved by groundwater. This creates voids underground which can eventually cause the surface to collapse. Option A describes flooding - related erosion, C is about rainwater drainage from a depression, and D is about tornado - related destruction, none of which are related to sinkhole formation.

Answer:

B. Groundwater dissolves the limestone and other rocks in the ground.
