Erosional and Depositional Landforms – Erosional landforms are landforms created due to the process of erosion. On the contrary, depositional landforms are created because of deposition processes. In Erosional landforms, the eroded material is taken away or transported by water, wind, etc., and finally gets sedimentation.

Valleys, potholes or depressions, rooted Meanders, and river Terraces are examples of erosional landforms. Examples of depositional landforms are alluvial fans, deltas, meanders, and braided channels.

Erosional Landforms

  • Chasms: Narrow, deep depressions cut out through vertical planes in the rocks.
  • Wave-Cut Platform: The sea tides knock against a cliff, and the cliff gradually erodes and exits.
  • Sea Cliff: It is the seaward boundary of the beach denoted by a steep scarp.
  • Hanging Valleys: The rivers appear to be hanging over the sea if the stream erosion flowing down is not able to keep speed with the pullout of the cliff.
  • Peneplain: If the level difference between the plain of marine erosion and the sea level is not significant, the substances of weathering transform it into a peneplain.

Depositional Landforms

  • Glacier Deposits: A deposit caused by glaciers containing rocks, soil, and other forms of debris over a landscape.
  • Moraines: Formed when a glacier gathers rock residue from the valley and transports it with the ice.
  • Beaches: The wave processes create beaches by sedimentation of sand, pebbles, and alluvium.
  • Dunes: It is created when sand depositions are blown off the beach and dried in the intertidal site.
