How does groundwater cause erosion and deposition?

Hello there! :) I provided info for you below, hope it helps.

SO basically...Running water on the surface of the earth erodes the land. Groundwater also can cause erosion under the surface. As water flows through the soil, acid is formed. This acid can cause minerals to be dissolved.

 A   >The answer<

Minerals that are carried in groundwater can also be deposited in other places. This cycle of erosion and deposition can cause underground caves to form. This happens especially in areas where there is limestone below the surface.

A cave is an underground opening. It has a connection to the surface of the earth. A cave is formed by the erosion of limestone under the ground. The acid water moves through the cracks in the limestone and makes them larger.

So the first one provided will be your answer! :3 <3
