Weathering, Erosion, Deposition

The natural chemical or physical processes that breaks down rock on Earth's surface.

• weathering

• erosion

• deposition

• freezering

The process by which water, ice, wind or gravity moves weathered rock and soil from one place to another.

• weathering

• erosion

• deposition

• dumptruck

This type of weathering occurs when rock is physically broken down into smaller pieces of rock.

• mechanical weathering

• chemical weathering

• erosion weathering

• deposition

This type of weathering occurs when rocks weaken then break down due to chemical changes in the composition of the rock.

How is mechanical weathering different from chemical weathering?

• Chemical weathering happens over much shorter time frame than mechanical weathering.
• Chemical weathering changes the chemical composition of rocks; mechanical weathering does not.
• Chemical weathering occurs only in tropical climates; mechanical weathering occurs only in cool climates.
• Chemical weathering occurs only in the mountains; mechanical weathering occurs only on flat land.
