Answer:
The answer that is not part of the types of water erosion is: mass wasting erosion.
Step-by-step explanation:
The main types of water erosion are splash erosion, sheet erosion, rill erosion, and gully erosion.
Mass wasting erosion if it is a type of erosion but not by water. It is a type of erosion that is generated mainly by the effect of gravity. It is also called mass movement, in which the material detaches from an inclined surface and falls as a result of gravity.
