How is mechanical weathering different from chemical weathering?

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

• Chemical weathering occurs in the tropics; mechanical weathering occurs in temperate climates.

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

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

What might cause mechanical weathering.

• Acid rain (carbonation)

• Rusting (oxidation)

• Growing plants and expanding ice

• Volcanic eruptions

What impact does weathering have on soil formation?

• Chemical weathering adds helpful chemicals to the soil.

• Rocks are broken down into smaller pieces, and finally into sediment.

• Mechanical weathering adds ice to the soil, which turns into water.

• Volcanic eruptions contribute metamorphic rocks to the soil.
