Which process is the force of the water washing away rocks?

Explanation:
The forceful impact of moving water that dislodges and carries away rock fragments is hydraulic action. This is a specific way erosion works, where the pressure and impact of water break pieces off the bed and banks so they can be transported by the current. Weathering only breaks rocks down in place, not remove them, and deposition is about sediments being dropped rather than removed. Erosion is the broad process of wearing away, but the mechanism described by “the force of the water washing away rocks” is hydraulic action.
