What causes depositions to have a layered look?
What causes depositions to have a layered look?
Sediment settles according to weight: the heaviest drops first and the lightest last, forming layers
What is the difference between weathering and erosion?
What is the difference between weathering and erosion?
Weathering: the breaking down of rocks into smaller pieces. Erosion: the movement of weathered materials from one place to another.
