1. What are the agents of mechanical weathering that you were able to circle?
- Examples of mechanical weathering include frost and salt wedging, unloading and exfoliation, water and wind abrasion, impacts and collisions, and biological actions. All of these processes break rocks into smaller pieces without changing the physical composition of the rock.
2. What are the types of chemical weathering found in puzzle?
- Chemical weathering changes the molecular structure of rocks and soil. For instance, carbon dioxide from the air or soil sometimes combines with water in a process called carbonation. This produces a weak acid, called carbonic acid, that can dissolve rock. Carbonic acid is especially effective at dissolving limestone.
3. How are mechanical weathering and chemical weathering similar?
- Mechanical weathering breaks rocks into smaller pieces without changing their composition. Chemical weathering breaks down rocks by forming new minerals that are stable at the Earth’s surface. Water, carbon dioxide, and oxygen are important agents of chemical weathering.
4. What is the difference between mechanical and chemical weathering?
- Mechanical weathering is the physical breakdown of rock into smaller pieces. Chemical weathering is the breakdown of rock by chemical processes.
