Hydrology, Groundwater and Karst Topography

Karst topography is an area that has

• lots of mountains

• many lakes

• caves and sinkholes

NGSS.MS-ESS2-2

Caves and sinkholes occur because

• acid rain weathers rock over time

• magma pushes its way through the rock forming holes

• Water wears away the rock forming caves

Limestone and dolomite are mostly composed of the mineral ________ which is soft and weathers easily.

• quartz

• calcite

• sulfur

One problem karst topography presents to groundwater is that it can easily contaminate well water for thousands of people from spills or leaks in the ground.

• true

• false
