How do sinkhole lakes form in limestone regions?
GeographyLakes
Quick Answer
Sinkhole lakes form when underground limestone dissolves and a surface depression fills with water. If the cavity collapses or sinks, a lake basin can be created.
The Full Story
Limestone and other soluble rocks can be slowly dissolved by slightly acidic groundwater. Over time, that process may open underground voids that weaken the land above. When the roof collapses or settles, a sinkhole forms, and rain or groundwater can fill the depression to create a lake. Many sinkhole lakes are part of karst landscapes and may appear or disappear over geologic time.
Key Facts
1.Sinkholes are common in karst terrain
2.Dissolution of limestone weakens the ground
3.Collapsed depressions can fill with water
