fill in the blanks in the table. agent type description 1. abrasion mechanical rock particles wear away rock 2. chemical forms from coal, oil, and gas burning freezing and thawing 3. breaks rock by ice wedging carbon dioxide 4. forms carbonic acid in water 5. chemical weathers marble and limestone 6. mechanical burrowing in the ground breaks rock plant growth 7. roots pry apart cracks in rock living organisms 8. produce weak acid that weathers rock oxygen 9. causes rust on some rock 10. mechanical sun or forest fire causes rock to crack
Answer
# Brief Explanations:
1. Abrasion is a mechanical weathering agent where rock - on - rock wear occurs.
2. Acid rain is a chemical weathering agent formed from burning coal, oil, and gas.
3. Freezing and thawing is a mechanical process due to ice wedging.
4. Carbon dioxide in water causes a chemical reaction to form carbonic acid.
5. Acid in water (e.g., from acid rain) is a chemical weathering agent for marble and limestone.
6. Animals burrowing is a mechanical weathering process.
7. Plant growth is a mechanical weathering process as roots expand in cracks.
8. Living organisms producing weak acids is a chemical weathering process.
9. Oxygen causing rust is a chemical weathering process.
10. Heat from sun or forest fire causing rock to crack is a mechanical weathering process.
