Types

Erosion-related:

Collapse-related:

  • Sinkhole: a depression formed as a result of the collapse of rocks lying above a hollow. This is common in karst regions.
  • Kettle: a shallow, sediment-filled body of water formed by melting glacial remnants in terminal moraines.
  • Thermokarst hollow: caused by volume loss of the ground as the result of permafrost thawing.

Impact-related:

Sedimentary-related:

Structural or tectonic-related:
