______________ a type of weathering in which a rock is changed into a different substance.
______________ this occurs when rocks rub against each other, becoming less jagged and more rounded.

Explanation:

1.

Acid rain is precipitation with acidic components that causes chemical weathering by reacting with rocks/minerals.

Oxidation is the chemical process where oxygen combines with a substance to form a new compound (e.g., iron + oxygen → rust).

Rust forms on iron - containing rocks/objects due to oxidation (reaction of iron with oxygen), giving an orange color.

Answer:

Acid rain
