A watering hole is a depression where water collects and animals come to drink

A depression in geology is a landform sunken or depressed below the surrounding area. Depressions may be formed by various mechanisms.

Erosion-related:

Glaciation-related:

  • A basin formed by glaciation – depressed by the weight of the ice sheet resulting in post-glacial rebound after the ice melts (the area adjacent to the ice sheet may be pulled down to create a peripheral depression.)[2]
  • Kettle: a shallow, sediment-filled body of water formed by melting glacial remnants in terminal moraine.[3]

Impact-related:

Sedimentary-related:

Structural or tectonic-related:

Volcanism-related:
