9. The breakdown do the materials of Earth’s crust into smaller pieces.
Weathering
The breakdown do the materials of Earth’s crust into smaller pieces.
Weathering causes
soil formation

10. Water causes weathering
What evidence of weathering do you see in this picture?

11. Wind causes weathering
Why wasn’t this mass of land weathered away?
What evidence of weathering do you see in this picture?

12. Describe how ice causes weathering?

13. What evidence of erosion do you see in this picture?
The process by which water, ice, wind or gravity moves fragments of rock and soil.
What evidence of erosion do you see in this picture?

14. Erosion is Movement of Sediment!
This process, known as Erosion, is gradually wearing down the surface of the earth.
Erosion is the process by which weathered rock and soil (sediment) are moved  from one place to another.
Erosion carves the Earth's surface creating canyons, gorges, and even beaches.
What do you think has caused this rock to look this way?

15. The intensity of wind erosion is determined by:
As the wind blows it picks up small particles of sand/sediment and blasts large rocks with the abrasive particles, cutting and shaping the rock.
The intensity of wind erosion is determined by:
Sum (amount)
Speed
Slope
Surface

16. Wind Erosion Creates sand dunes Greatest impact in deserts Removes
fertile topsoil

17. Water Causes Erosion runoff, rivers and, streams
Creates MOST of the changes
in the Earth's landscape!
