How does a sinkhole form?

• Stalactites erode the ceiling of a cavern.

• A flowing stream in the mountains erodes sediment and the ground caves in.

• Underground water erodes rock forming a cavern, and over time the cavern's roof collapses.

Groundwater is the water located within the rocks below Earth's surface. When underground erosion happens, what forms?

• canyons

• caverns

• channels

• valleys
