1. Erosion

2. Erosion – the process in which weathered particles are picked up and moved from one place to another.

3. Weathering and erosion are two very different processes that tend to act sequentially #21

4. Erosion
Erosion is the movement of rock particles #22

5. Erosion
Erosion transports weathered rock material #23

6. Erosion
Water, wind and ice are agents of erosion #24

7. Erosion
Water, wind and ice are agents of erosion #24

8. Deposition – the part of the erosion process in which sediment is placed in a new location

9. Deposition
Deposition occurs where the agents (forces) of erosion lay down sediment #25

10. Deposition
Dirt from mountain tops can be carried downhill to fill in valleys. This is called deposition #26

11. Deposition Example
Dirt from mountain tops can be carried downhill to fill in valleys.

12. Deposition Example
Area of the shoreline made up of material (usually sand) deposited by waves.

13. Gravity’s Effect On Erosion and Deposition

14. Mass Movement
Movement of rock, soil, or snow, down a slope.

15. Waves erode the shoreline #27

16. #28 What are the three major ways in which erosion moved sediment?
water
wind
ice 

17. Weathering and erosion wear down, and deposition fills in Earth’s surface #29
delta

19. Rivers can carve a valley through rock with a river flowing through it while a glacier can carve a valley where only rocks remain. When the glacier retreats or melts it leaves behind a valley without water #31

20. Rivers can carve a valley through rock with a river flowing through it while a glacier can carve a valley where only rocks remain. When the glacier retreats or melts it leaves behind a valley without water #31

21. If there is a deep valley without any water. How did it form? Possible?
glacier

22. Wind, water, and gravity all combine to move dirt around
 Wind, water, and gravity all combine to move dirt around. Of the three, water is responsible for moving the most amount of soil #32

23. The agent of erosion that carries the largest rocks is glaciers #30
