How does air pollution impact chemical weathering? (1 point)

Question

• pollutants prevent carbon from mixing with water.
• pollutants cover rocks with a toxic layer that weakens them.
• Pollutants mix with air and water to make acid rain.
• Pollutants react with minerals inside rocks and weaken them.

Answer 1

Air pollution impacts chemical weathering primarily through the formation of acid rain. Thus, the correct option is:

• Pollutants mix with air and water to make acid rain.

Acid rain accelerates the chemical weathering of rocks by increasing the acidity of precipitation, which can react with minerals and lead to their dissolution and weakening.
