information about erosion transportation s depitional work of river landform
Answers
Answer:
As the river makes its way to the middle course, it gains more water and therefore more energy, so material can be carried in suspension and is used to erode the river banks. Lateral erosion starts to widen the river. When a river flows over flatter land it develops large bends called meanders.
As a river goes around a bend, most of the water is pushed towards the outside. This causes increased speed due to less friction and therefore increased erosion (through hydraulic action and abrasion).
The lateral erosion on the outside bend causes undercutting of the river bank to form a river cliff.
There is less water on the inside bend of a meander so friction causes the water to slow down, lose energy and deposit the material the river is carrying, creating a gentle slope.
The build-up of deposited sediment is known as a slip-off slope (or sometimes river beach).

Answer:
In earth science, erosion is the action of surface processes (such as water flow or wind) that removes soil, rock, or dissolved material from one location on the Earth's crust, and then transports it to another location
Transport, or transportation, is the movement of humans, animals and goods from one location to another. In other words, the action of transport is defined as a particular movement of an organism or thing from a point A to a point B. Modes of transport include air, land, water, cable, pipeline and space.
The river starts to flow through a broad, level plain with heavy debris brought down from upper and middle courses. ... The work of the river is mainly deposition, building up its bed and forming an extensive flood plain. Landforms like braided channels, floodplains, levees, meanders, oxbow lakes, deltas etc.
