Question

how do rock types contribute to the rate of weathering?
porous minerals weather faster.
harder minerals break apart more easily.
minerals that dissolve easily weather slower.
permeable rocks have less chemical reactions.

Explanation:

• Porous rocks have more surface area exposed to weathering agents like water and air, accelerating both physical and chemical weathering.
• Harder minerals are more resistant to breaking apart, so they weather slower.
• Minerals that dissolve easily undergo chemical weathering quickly, so they weather faster, not slower.
• Permeable rocks allow water to flow through, increasing chemical reactions that drive weathering, not reducing them.

Answer:

A. Porous minerals weather faster.
