Here's how it works:

* Erosion: Weathering and other forces break down rocks into smaller pieces.

* Transportation: These smaller pieces, called sediment, are transported by wind, water, or ice.

* Deposition: When the transporting force loses energy, the sediment settles out and accumulates. This is deposition.

Examples of deposition:

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

* Wind: Wind can carry sand and dust long distances, depositing it as dunes or loess.

* Glaciers: Glaciers carry rocks and sediment, dropping them off when they melt, creating moraines and glacial valleys.

Key point: Deposition is an important part of the rock cycle. It's how sediments eventually turn back into sedimentary rocks!
