Deposition is the process where the agents of erosion (like wind, water, ice, or gravity) lay down the sediment they have been transporting.

Think of it like this:

* Erosion: Picking up and carrying away sediment.

* Deposition: Dropping off the sediment.

Here are some examples of deposition:

* Rivers: As a river slows down, it loses energy and deposits sediment, forming deltas, floodplains, and riverbeds.

* Wind: Wind carries sand and dust, depositing them in dunes, loess deposits, and sandbars.

* Glaciers: As glaciers melt, they release the sediment they were carrying, forming glacial valleys, moraines, and outwash plains.

So, deposition is the direct result of erosion; it's the final step in the process of moving sediment from one location to another.
