Answer 1

D) groundwater dissolves the limestone and other rocks in the ground

Answer 2

The correct option is D: Groundwater dissolves limestone and rocks in the ground. This is a type of chemical process that leads to the formation of sinkholes.

Step-by-step explanation:

A sinkhole is a depression of hole in the ground formed because of the collapse of a surface layer. Usually the dissolution of rocks of carbonate nature may result in the formation of a sinkhole.

Sinkholes do not have any external drainage and therefore when there is rain, water collects in sinkholes and drains into the sub-surfaces.
