Description : Hydraulic Action is a type of erosion caused by – (1) Running water (2) Wind (3) Glacier (4) None of these
Last 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.
