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.

What is erosion?

• The movement of sediment

• The breaking of sediment

• The dropping of sediment
