Question

Quizplus · Accepted Answer

The acidity that speeds up chemical weathering in nature primarily comes from organic acids produced by the decay of plants, acid rain which is the result of industrial pollutants reacting with water vapor in the atmosphere, and sulphuric acid formed through the oxidation of pyrite. These acidic substances contribute to the breakdown of rocks and minerals, facilitating chemical weathering.
