How is mechanical weathering different from chemical weathering?

• chemical weathering occurs in the tropics; mechanical weathering occurs in temperate climates

• Chemical weathering happens over a much shorter time frame than mechanical weathering.

• Chemical weathering occurs in the mountains; mechanical weathering occurs on flat surfaces.

• chemical weathering changes the chemical composition of materials; mechancial weathering does not.

What might cause mechanical weathering.

• Acid rain (carbonation)

• Rusting (oxidation)

• Growing plants and expanding ice

• Volcanic eruptions
