1. Changing Earth’s Surface

2. Weathering Erosion and Deposition Weathering The process that breaks down rock and other substances at Earth’s surface

3. Erosion The removal of rock particles by wind, water, ice, or gravity Weathering Erosion and Deposition

4. Erosion The process by which natural forces move weathered rock and soil from one place to another Weathering Erosion and Deposition

5. Sediment The material moved by erosion Weathering Erosion and Deposition

6. Sediment May be pieces of rock, soil, or the remains of plants and animals Weathering Erosion and Deposition

7. Deposition When wind and water finally calm, the rocks and the sediment settle to the bottom Weathering Erosion and Deposition

8. Deposition Changes the shape of the land Weathering Erosion and Deposition

9. Act together in a cycle that wears down and builds up Earth’s surface Weathering Erosion and Deposition

10. The force that moves rock and other material downhill Weathering Erosion and Deposition Gravity

11. Any of several processes that move sediment downhill Weathering Erosion and Deposition Mass Movement

12. Landslides, Mudflows, Slump, Creep Weathering Erosion and Deposition Types of Mass Movement

13. Most destructive mass movement Types of Mass Movement Landslide Rock and soil slide quickly down a steep slope

14. Rapid downhill movement of water, rock, and soil Types of Mass Movement Mudflow

15. Types of Mass Movement Slump A mass of rock and soil suddenly slips down a slope in one large mass

16. Types of Mass Movement Creep Very slow downhill movement of rock and soil
