What are the 3 types of eroding action by water?

The three types of eroding action by water are hydraulic action, abrasion, and solution. Hydraulic action occurs when the force of moving water dislodges and removes materials from riverbanks and beds. Abrasion happens when particles carried by water scrape and wear away surfaces, contributing to erosion. Solution involves the chemical dissolution of soluble materials, such as limestone, by water, leading to the gradual wearing away of the landscape.
