1. the three main surface processes are weathering, weathering, & deposition.
2. weathering is the chemical or physical breakdown of rock.
3. chemical weathering occurs when water or acidic rain dissolves minerals in a rock causing it to wear down over time.
4. physical weathering (or mechanical weathering) occurs when rocks are physically broken down into smaller particles or sediment.
5. tectonic types of movements of earth and the temperature changes cause physical weathering. wind, , and cause rocks and particles to collide and break.
6. plant roots into rocks and break them apart.
7. water seeps into rocks and expands when it , causing rocks to or eventually break apart!
8. florid experiences physical and weathering.

Explanation:

1. The three main surface - geological processes are weathering, erosion, and deposition.
2. Weathering is the breakdown of rock by chemical or physical means.
3. Chemical weathering involves dissolution of rock minerals by water or acidic rain.
4. Physical (mechanical) weathering is the physical breakdown of rocks.
5. Tectonic movements and temperature changes cause physical weathering. Wind, water, and ice can also cause rock - particle collisions.
6. Plant roots grow into rocks and break them.
7. Water seeping into rocks expands when it freezes, causing rocks to crack or break.
