1. Water:

* Erosion: Rain, rivers, and ocean waves wear away rock and soil, carrying it downstream or out to sea.

* Deposition: When water slows down, it loses energy and drops the sediment it was carrying. This can create deltas, sandbars, and beaches.

2. Wind:

* Erosion: Wind can pick up and carry sand, dust, and smaller particles, especially in arid or desert environments.

* Deposition: When wind slows down, it deposits the material it was carrying, creating sand dunes, loess deposits, and dust storms.

3. Glaciers:

* Erosion: The immense weight and slow movement of glaciers carve out valleys, transport rock and sediment, and create U-shaped valleys.

* Deposition: As glaciers melt, they deposit the material they carried, creating moraines, outwash plains, and other glacial landforms.
