I agree that the first two are correct. Here is a site that lists acid rain, water, oxygen, and carbon dioxide as the four major types of chemical weathering.

To find the answer to question 1, we need to understand the process described. Acid rain causes changes in minerals in rocks, suggesting that a chemical reaction is taking place. Among the given options, the process of changing minerals in rocks through chemical reactions is called chemical weathering. Therefore, the correct answer is (a) chemical weathering.
For question 2, we are looking for a landform that was formed by erosion. Erosion refers to the process of wearing away or transporting materials by natural forces such as water, wind, or ice. Among the given options, the Grand Canyon is a prime example of a landform that resulted from erosion. Therefore, the correct answer is (c) the Grand Canyon.
In question 3, we are asked to identify a cause of chemical weathering that is NOT valid. Chemical weathering is the breakdown or alteration of rocks and minerals through chemical reactions. Among the given options, water, oxygen, and carbon dioxide are all known to contribute to chemical weathering processes. However, oxygen is not a direct cause of chemical weathering. Therefore, the correct answer is (c) oxygen.
