Question

Match the descriptions with the ways that rocks are weathered.



carries bits of rock formations and sand to new places



crashes against tall cliffs to wear away cracks or soft areas



expands in cracks and small openings to split rock



grow on top of or in the cracks of rocks



soaks into the ground and flows over rocks



wears away at the rock in riverbanks

Answer 1

Here are the descriptions matched with the ways that rocks are weathered:

1. **Carries bits of rock formations and sand to new places** - **Erosion by water or wind**

2. **Crashes against tall cliffs to wear away cracks or soft areas** - **Wave action (mechanical weathering)**

3. **Expands in cracks and small openings to split rock** - **Frost wedging (freeze-thaw weathering)**

4. **Grow on top of or in the cracks of rocks** - **Biological weathering (plants and roots)**

5. **Soaks into the ground and flows over rocks** - **Surface runoff (water erosion)**

6. **Wears away at the rock in riverbanks** - **River erosion (hydraulic action)**

These match the descriptions provided with their appropriate weathering processes.
