Accepted Answer

Oxidation

Answer

Acid rain

Answer

Reaction to water

Answer

Exfoliation

Question 19

What is the difference between weathering and erosion?

Accepted Answer

Weathering breaks down rocks, and erosion carries the broken pieces away.

Answer

Erosion breaks down the rocks, and weathering carries the broken pieces away.

Answer

Erosion carries broken pieces away, and weathering builds the pieces back up into another land mass.

Answer

Weathering carries broken pieces away, and erosion builds the pieces back up into another land mass.
