Answer:

1.A

2.A

3.A

4.C

5.B

6.A and B. Acidic water can cause chemical weathering while in boating and fishing, there's not really a direct connection between the two, unless it's illegal fishing that uses explosives that could both weather minerals under water and destroy underwater life.

7.C

8.D

9.Temperature changes can also contribute to mechanical weathering in a process called thermal stress. Changes in temperature cause rock to expand (with heat) and contract (with cold). As this happens over and over again, the structure of the rock weakens. Over time, it crumbles.

10.B
