Erosion Processes

Erosion Processes

1. Abrasion / Corrasion

   • Smaller rocks carried by the river erode the beds and sides.

2. Hydraulic Action

   • The power of the water removes material.

3. Attrition

   • Rocks and pebbles crash into each other and break up.

4. Corrosion

   • Some rocks dissolve in the water.
