1 Answer

Answer :

(1) Running water Explanation: Hydraulic action is one of the main forms of river erosion (example, of erosion due to running water) in which the force of the river against the banks can cause air to be trapped in cracks and crevices. The pressure weakens the banks and gradually wears it away.
