4. Weathering, Erosion and Deposition

5. Weathering
The breaking down or disintegration of substances such as rocks and minerals by physical, chemical or biological processes

6. Weathering
Weathering acts slowly, but over time will break down the largest and hardest of rocks
mechanical weathering – rock is physically broken down into smaller pieces by processes
chemical weathering – process that breaks down rocks through chemical changes

7. Weathering- Mechanical

8. Weathering - Chemical

9. Erosion
The movement of sediment or soil from one location to another by means of water, ice or wind

10. DEPOSITION
When particles carried by water, ice, or wind are deposited (dropped) in another location
