Explanation:

Question 1

We need to find the precipitation that causes chemical weathering. From the vocabulary list, acid rain is a type of precipitation that is acidic and causes chemical weathering of rocks and other materials.

The process of oxygen combining with a chemical to form a new substance is called oxidation. This is a key concept in chemical weathering where substances react with oxygen.

When iron undergoes oxidation, it forms rust, which has an orange color. So the process that produces an orange color on iron rocks or objects due to oxidation is rusting, and the term from the list is rust.

Answer:

Acid rain
