Question

1. weathering that occurs when iron-rich minerals become a dark red color is called ______abrasionoxidationcarbonationhydrolysis

Explanation:

Oxidation is a type of chemical weathering where iron-rich minerals react with oxygen, causing them to turn a dark red (rust-like) color. Abrasion is physical weathering via friction, carbonation involves reaction with carbon dioxide, and hydrolysis is breakdown via water, none of which cause this specific color change in iron-rich minerals.

Answer:

B. oxidation
