How karst forms. Karst 2-1. Some rocks, such as limestone, can be dissolved by weakly acidic water. Karst 2-2. Carbon dioxide in air and soil combines with water to form weak carbonic acid. Karst 2-3. Water containing carbonic acid can slowly dissolve limestone, especially along fractures.

Presentation Transcript

  1. How karst forms. Karst 2-1

  2. Some rocks, such as limestone, can be dissolved by weakly acidic water. Karst 2-2

  3. Carbon dioxide in air and soil combines with water to form weak carbonic acid. Karst 2-3

  4. Water containing carbonic acid can slowly dissolve limestone, especially along fractures. Karst 2-4

  5. As fractures enlarge, they can become caves. Karst 2-5

  6. Caves can be very large underground. Karst 2-6

  7. Collapse of cave roofs causes sinkholes. Karst 2-7

  8. Natural filling of sinkholes sevelops gently rolling sinkhole plains. Karst 2-8

  9. Dissolving large amounts of limestone leaves behind remnant rock towers. Karst 2-9
