1. slump

mixture of weathered rock, organic matter, water, and air

2. mechanical weathering

erosion caused by wind that can lower the land's surface

3. runoff 4. soil 5. mass movement 6. creep 7. topography 8. chemical weathering 9. erosion 10. deflation 11. abrasion

gravity causing rock or sediment to move downhill

thick layers of loose sediment moving downhill along a curved surface

process in which composition of the rock changes
