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.
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.
first the weathering happens which causes an erosion which makes deposition.
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.
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.
A dis-conformity is an unconformity representing a period of erosion or lack of deposition in a sedimentary rock section.
A waterfall is formed primarily by erosion, as water flows over hard rock layers and gradually wears them down to create a steep drop. However, some deposition may also occur at the base of the waterfall as sediment collects from the eroded material.
A waterfall is primarily associated with erosion rather than deposition. The force of the water flowing over the edge of a waterfall can erode the rock below, causing the waterfall to retreat upstream over time.
Deposition
A waterfall is primarily created by erosion, as water flowing over a hard rock layer gradually wears it down and forms a drop. Deposition can occur at the base of the waterfall where the water slows down and deposits sediment, but the main process responsible for creating the waterfall is erosion.
Creep is formed by erosion.
That are fined by erosion.
The Nile River is formed by Deposition.
They are formed by deposition of sediments from rivers and streams.
The Arkansas River was formed by erosion, not deposition.
A split can be formed by both erosion and deposition. Erosion processes like weathering and water flow can create splits in rocks or landforms, while deposition of sediments can also fill in gaps and create splits in formations.
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.
A beach is formed by both erosion and deposition. Waves erode the coastline by picking up and moving sand and sediment, which then gets deposited along the shoreline to create a beach. Erosion and deposition processes continually shape beaches over time.
