Question

1. What is the result of a rock undergoing physical weathering?

2. How does chemical weathering change rock? Provide examples.

3. What kinds of rocks weather most rapidly?

4. Why is weathering slow in cold, dry places?

Thanks~!​

Answer 1

Answer:

because it is heavy and the heat

Answer 2

1. Physical weathering is caused by the effects of changing temperature on rocks, causing the rock to break apart. The process is sometimes assisted by water.
2. Chemical weathering occurs when water dissolves minerals in a rock, producing new compounds. Hydrolysis occurs, for example, when water comes in contact with granite. Feldspar crystals inside the granite react chemically, forming clay minerals. The clay weakens the rock, making it more likely to break.
3. Igneous rocks, especially intrusive igneous rocks such as granite. Other types of rock, such as limestone, are easily weathered because they dissolve in weak acids.
4. Rate of weathering depends on temperature and moisture. Cold and dry places have less water.
