wave cut cliffs
A canyon or a valley may form when more erosion takes place than deposition. This can happen when the forces of erosion, such as water or ice, remove material faster than it can be replenished by deposition, resulting in a deep and steep-walled feature.
It is formed from both. The rocks forms the falls had one had to be deposited and their current erosion by the river is resulting in the waterfall.
When deposition finally seals off the cutoff from the river channel, an oxbow lake is formed.
Sedimentary rocks are created from erosion and deposition. These are formed when sediments (such as sand, mud, or pebbles) are deposited, compressed, and cemented together over time by pressure and chemical reactions. Examples include sandstone, conglomerate, and shale.
A delta is formed by deposition. Deltas are landforms that are created where a river meets a body of water, like an ocean or a lake. As the river flows into the larger body of water, it slows down, causing sediment it was carrying to settle and build up over time, forming the delta.
unconformity. It represents a period of missing time in the rock record, where deposition was not continuous due to erosion or non-deposition of sediment layers.
Meanders are primarily formed by erosion. The moving water of a river erodes the outer bank of a bend while depositing sediment on the inner bank, leading to the formation and migration of meanders over time.
Deposition
Creep is formed by erosion.
A cirque, also known as a Cwm or Corrie, is a feature of glacial erosion, formed in a mountainside.
The Nile River is formed by Deposition.
Mushroom rocks are typically formed by erosion. Over time, softer rock material around a harder, more resistant rock can erode away faster, leaving behind the mushroom-like formation. Deposition can also play a role in shaping these structures as sediment accumulates around the base of the rock.
They are formed by deposition of sediments from rivers and streams.
The Arkansas River was formed by erosion, not deposition.
Sea cliffs are primarily formed by erosion, typically from the action of waves and weathering processes wearing away at the coastal rock over time. Deposition can also play a role in the formation of sea cliffs when sediments accumulate at the base of the cliff.
The two features formed by wave deposition are islands and beaches.
Wind erosion is the primary process that forms sand dunes. As wind moves across a landscape, it picks up loose sand particles and deposits them in areas where the wind slows down, creating dunes. Over time, the accumulation of sand particles builds up into the characteristic shape of sand dunes.
Barrier islands are primarily formed by deposition, where sediments such as sand and gravel are deposited by ocean currents and waves. Erosion can also contribute to their shape and size over time, but the main process driving their formation is deposition.
