D)lithification.

Question

Quizplus · Accepted Answer

Physical abrasion, such as the rubbing and scouring action of rocks and sediments carried by the water, is the main source of erosion in stream channels. Chemical erosion (B) can also contribute to erosion, but it is not the main source. Laminar flow (C) refers to the smooth, uninterrupted flow of water and does not directly cause erosion. Lithification (D) is the process by which sediment becomes rock and is not related to erosion.
