Which of the following describes the process of erosion by water?

The process of erosion by water is primarily characterized as physical weathering. This is because physical weathering involves the mechanical breakdown of rocks and soil, which can occur through the action of water. When water flows over the surface of the land, it can dislodge particles, transport them, and cause the continuous reshaping of landscapes. This can be seen in riverbanks where the flow of water gradually erodes rock and soil, leading to the formation of valleys and other geological features.

Physical weathering emphasizes the physical forces and movements that cause materials to break away from larger masses without altering their chemical composition. Consequently, abrasion, hydraulic action, and the impact of flowing water play significant roles in the erosion process under this category. Recognizing that water acts as a powerful agent of physical weathering helps to understand the impact of natural processes on soil conservation and landscape formation.
