Below are the four agents of erosion, so take what you need:
- Fluvial erosion - rivers mainly. Rivers erode by hydraulic action, abrasion, attrition and solution. Deposition occurs because the river has run out of energy, or energy is low.
- Marine erosion - oceans and seas. These erode by hydraulic action and abrasion mainly, as the ocean has great sheer force. They do not transport much material, as most of the work is done by gravity, so most material is left directly under where it came from, but separate nonetheless.
- Glacial erosion - glaciers. Glaciers erode by plucking and abrasion, then deposit the moraine (glacial load) at the snout
- Aeolian erosion - wind. Wind erodes mainly by blasting sediment at rocks, which is classic abrasion. Sediment is often deposited as a dune.
All agents of erosion cause both erosion and deposition as ultimately all eroded material is deposited.
