Which is typically the least important form of stream erosion?

Question

Quizplus · Accepted Answer

Corrosion, also known as solution, involves the dissolution of rock minerals by water. It is typically considered the least important form of stream erosion compared to abrasion (the grinding away of rock by other rock particles carried in water), hydraulic action (the force of the water itself breaking rock particles away from the river channel), and headward erosion (the process by which a stream channel lengthens up its slope as the flow of water increases). Corrosion's impact is more subtle and chemically based, making it less immediately impactful in terms of physical landscape alteration than the mechanical actions of abrasion, hydraulic action, and headward erosion.
