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 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
