Mechanical and Chemical Weathering
Use your notes to answer the following questions:
1. Compare chemical and mechanical weathering.
2. How are ice and water involved in mechanical weathering?
3. How is temperature related to mechanical weathering?
4. What is hydrolysis, and what type of weathering is it?
5. Explain how oxygen is connected to chemical weathering.
6. What are some factors that you think can control the rate at which a rock weathers?
7. Consider the climate and physical features of the region in which you live. Does it rain
frequently? Is it dry or windy? How does the temperature vary during the year? Based on
your knowledge of the climate and physical features of your area, predict what types of
weathering are likely to occur.
