When rivers pick up rocks and sediment, they often hit and scrape against the river bed, wearing it away. Which of the four types of fluvial erosion is this?
The type of fluvial erosion described in your question is called “abrasion.”
Explanation: Abrasion occurs when the material carried by the river, such as rocks and sediment, collides with the river bed and banks, effectively wearing them away. This process can deepen and widen the river channel over time as the movement of these materials scrapes against the surfaces they come into contact with.
