2. Weathering
Weathering is the process of wearing away rocks by natural means.
This is the slowest of all destructive processes.

3. What is Erosion?
Erosion is the process of moving sediment by wind, water, or ice.
Erosion continues the work of weathering by loosening and transporting particles/sediment.

4. Deposition
Deposition is deposits of material which are added to a landform.
Delta is the area at the end of the river, before it enters the ocean, where sediment is deposited to form land.

5. Glaciers
Glaciers are large, slow moving chunks of ice. Sometimes rivers of ice.
