Erosion by Groundwater

Erosion By Groundwater

Groundwater is water that moves slowly through spaces in soil and rock beneath Earth’s surface. Over time, groundwater can cause erosion by dissolving certain types of rock, especially limestone. This type of erosion happens underground and leads to the formation of caves,...

Rainwater absorbs carbon dioxide from the air, forming a weak acid called carbonic acid.

When this rainwater soaks into the soil and rock, it moves slowly downward due to gravity, becoming groundwater.

As this slightly acidic groundwater flows through cracks and tiny spaces in rock, it gradually dissolves limestone, creating undergro...
