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 the mountains; Mechanical weathering occurs on flat surfaces

• Chemical weathering changes the chemical compositions 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.

What types of rocks are formed by weathering?

• Metamorphic rocks

• Igneous rocks

• Sedimentary rocks

How long does the weathering process take?

• Years and years

• Exactly one year

• No more than a month

• A few days
