What are depositional and erosional landforms?

DefineErosion is the process of wearing down by wind, water or other natural agents. It can dissolve rock, by weakening it or turning it into small fragmentsDeposition is the process by which sediment settles out of the water or wind carrying it, and is deposited ("placed") in a new location. Examples with Definition+ DiagramsFor erosion: Knickpoint A knick point is a sharp break of slope in the smooth, concave long profile of a river. It is usually marked by the presence of a waterfall (or a series of rapids).Formation: Knickpoints are formed when the river cuts down, adjusting its profile to a new base level. This causes a sudden change is gradient, after which the knickpoint moves upstream via headward erosion as river adjusts to a new energy balance. Some knick points are sharply defined, for example waterfalls, whereas others are barely noticeable.For deposition: Eyot An eyot (or ait) is a small island in a braided river. Formation:They are typically formed by the deposition of sediment and silt in the water.
