2. Weathering, Erosion , & Deposition The Wearing Down and Building Up of Earth

3. Natural Forces move and deposit sediments
The Grand Canyon was formed by the movement of water
Water flowed over the land and carried away weather rock and soil
This shaped a valley where water flowed creating the canyon

4. Weathering
Weathering is the process by which natural forces break down rocks. The more surface area exposed, the faster weathering happens.
There are two types of weathering, mechanical and chemical.

5. Weathering
Mechanical Weathering is the breaking up of rocks by physical forces
Ice wedging, pressure release, plant growth, or abrasion
Chemical Weathering is the breakdown of rocks by chemical reactions that change the rocks’ composition.
Dissolving or rusting

6. Weathering

7. Waves and Wind Shape the Land
What natural force created these isolated stone pillars?
The movement of water (waves). The constant action of waves breaking against the cliffs slowing wore the rock cliff away

8. Erosion Erosion is the removal of rock particles from a location.
Caused by water, wind, ice, or gravity.

9. WATER EROSION
Water sources such as rivers, streams, ocean tides, and runoff can move rock particles away....

10. Water Erosion-Rivers
Rivers and streams carry sediment. As the sediment moves mechanical weathering occurs.
Through water erosion, rivers create waterfalls, flood plains, and valleys.

14. Water Erosion-Waves
Waves- waves shape the coasts by transporting sand. While the sand is moved, mechanical weathering occurs.
Waves create sea stacks, caves, arch, and wave-cut cliffs.

15. Erosion by Runoff
As water from precipitation (rain, snow, etc.) moves over the land, it carries particles with it. The moving water is called runoff.
Runoff creates rills and gullies.

16. WIND EROSION
Sometimes the wind can move rock particles away: this can lead to dust storms!

17. WIND EROSION
Wind Erosion creates dust storms, hoodoos, and arches.

18. Ice Erosion
As a glacier flows over the land, it picks up rocks in a process called plucking.

19. Ice Erosion
Ice erosion creates: U-shaped valleys, glacial lakes, moraines, drumlins, and kettle lakes.

20. Ice Erosion
Ice erosion creates: U-shaped valleys, glacial lakes, moraines, drumlins, and kettle lakes.

21. Erosion by Gravity Gravity causes sediment to move downhill.
It creates: landslides, mudflows, and creeps.

22. Weathering and Erosion work together continuously to wear down and carry away the rocks at the Earth’s surface!!!!!
END - Erosion

23. Deposition
Deposition is the process in which sediment laid down in new locations.
Caused by water, wind, ice, and gravity.
