Question

what is the definition of erosion?
the process by which sediment settles out of water
the soil and rocks deposited by moving water
the process by which a river moves soil and rock
the waterways that move soil and rock

Explanation:

To determine the correct definition of erosion, we analyze each option:

• The first option describes sedimentation (sediment settling), not erosion.
• The second option refers to deposition (materials deposited by water), not erosion.
• The third option: Erosion is the process of moving soil, rock, etc., by agents like rivers. This matches the definition.
• The fourth option describes waterways (like rivers) themselves, not the erosion process.

Answer:

C. the process by which a river moves soil and rock
