1. Weathering and Erosion

2. Weathering Weathering - the process that breaks down rocks into smaller pieces

3. The 3 types of weathering Physical Weathering (mechanical) Chemical Weathering Biological Weathering

4. Weathering Physical Weathering (mechanical) - is weathering that is caused by a physical force. This can be caused by water, ice, and wind. Water Ice Wind

5. Weathering Chemical Weathering - Occurs when there is a chemical reaction between water, air, or another substance and the material in rocks. This can be caused by water and air. Air Water

6. Weathering Biological Weathering - Weathering (physical or chemical) that is caused by living things. Lichens & Moss Animals Tress and Plants

7. Erosion Erosion _ the movement of weathered rock material from once place to another Erosion can be fast process or a slow one that occurs over thousands of years

8. Erosion can be caused by… Glaciers (Ice) Running Water Waves Wind Gravity

9. Erosion Glaciers (Ice) – A slowly moving mass or river of ice formed by the accumulation and compaction of snow on mountains or near poles. Glaciers move downhill and because their massive size and power they can carve away big chunks of land Glaciers can cause significant DAMEGE!

10. Erosion Glaciers (Ice) As you can see glaciers can carve away land

11. Erosion Running Water – As water flows over land it can remove rocks as well as to carve huge chunks of land

12. Erosion Waves – When waves hits rocks because of the strength and power they have they can break rocks or move rocks. it can cause erosion

13. Erosion Waves

14. Erosion Wind – Wind carry's away sediment from one place to another (long distances) When winds stops going fast is when the sediment goes back to the ground

15. Erosion Wind

16. Erosion Gravity – Can cause large chucks of land to fall downhill

17. Erosion

18. Deposition – The settling of eroded rock material on Earth’s surface

19. How do they work together to affect rocks? This two work together because at the beginning its a big normal rock then water, ice, wind, and temperature hit the rock and that process makes it brake down into smaller pieces. Days, weeks months, or even year go on a then glaciers, running water, waves wind, and gravity hit the smaller pieces of rock and moves them from one place to another.
