3. Erosion that occurs when rocks and sediment carried by moving water scrape and grind against a riverbed or cliff face, wearing it away like sandpaper.
4. The forward movement of water up a beach after a wave breaks. It carries sand and sediment up the shore.
6. The geological process where earthen materials (like rock and soil) are worn away and transported by natural forces such as water, wind, or ice.
7. A form of erosion where loose rocks and pebbles carried by water smash into each other. This breaks them down into smaller, smoother, and rounder pieces.
8. A dual-purpose term. As an erosion type (also called corrosion), it refers to acidic water dissolving certain rock types like limestone. As a transportation type, it refers to dissolved minerals being carried along invisibly in the water.

1. a very steep, vertical, or overhanging face of rock, earth, or ice
2. Backwash: The backward movement of water down a beach after a wave has broken.
5. Erosion caused by the sheer force of moving water. Water traps air in cracks of a cliff or riverbank, compressing the air until the rock fractures and breaks apart.
6. The geological process where earthen materials (like rock and soil) are worn away and transported by natural forces such as water, wind, or ice.
