Section Summary

I Groundwater dissolves limestone and forms underground caves.

I Sinkholes form at Earth's surface when bedrock is dissolved or when caves collapse.

I Irregular topography caused by groundwater dissolution is called karst topography.

I The precipitation of dissolved calcite forms stalactites and stalagmites in caves.

Understand Main Ideas

1. iman4KHB Analyze how limestone is weathered, and identify the features that are formed as a result of this dissolution.

2. Identify the acid that is most common in groundwater.

3. Illustrate in a series of pictures how caves are formed.

4. Examine Why is hard water more common in some areas than others? Think Critically

5. Compare and contrast the formation of stalactites and stalagmites.

6. Analyze how you might be able to tell an area of karst topography on a topographic map.
