Stream erode their channels by abrasion, grinding, and by dissolving soluble material.
ocean sea and river
The three ways of river erosion are hydraulic action (force of water on the river banks), abrasion (wearing down of the riverbed by sediment), and attrition (erosion caused by rocks and sediment carried by the river rubbing against each other).
deflation and abrasion
because it cool
Two main ways a river might change the land around it would be to erode the surrounding landscape (like how the Colorado river formed the grand canyon) and to fertilize the soil around it (like the Nile river).
