Deposition is the process by which sediments are laid down on the surface of the Earth. It is the opposite of erosion, which is the process by which sediments are transported away from the Earth's surface.

A diagram representing deposition would show sediments being transported by water, wind, or ice and then being deposited on the ground. The sediments could be sand, gravel, mud, or other materials. The diagram would also show the direction of the transport and the location of the deposition.

Here is an example of a diagram representing deposition:

[Image of a diagram showing a river flowing through a valley. The river is carrying sediment, which is being deposited on the floodplain. The floodplain is a flat area of land that is adjacent to the river. The sediment is being deposited because the river is slowing down as it flows through the valley. The diagram also shows the direction of the river flow and the location of the deposition.]
