WED (weather, Erosion, Deposition)

The mechanical and chemical processes that change objects on Earth’s surface over time. Breaks rocks down into sediment.

• Weathering

• Erosion

• Deposition

the minerals in rocks are changed into new minerals. A chemical reaction takes place and new substances are

formed.

• Mechanical Weathering

• Rounding

• Chemical weathering
