What is the difference between weathering and erosion?
Erosion breaks down the rocks, and weathering carries the broken pieces away.
Erosion carries broken pieces away, and weathering builds the pieces back up into another land mass.
Weathering carries broken pieces away, and erosion builds the pieces back up into another land mass.
Weathering breaks down rocks, and erosion carries the broken pieces away.
