Question

How does groundwater cause erosion and deposition?

Answer 1

Ground water causes erosion when it's constantly running/landing on the same surface and each time it does this, it washes away a bit at the surface at a time. it causes deposition when it carries the eroded materials away and drops it off somewhere else.

Answer 2

Groundwater also can cause erosion under the surface. As water flows through the soil, acid is formed. ... 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.
