Answer
Yes, I agree that weathering is a natural process, but human activities can accelerate it in the following ways:
- Mining and quarrying expose fresh rock surfaces, making them more vulnerable to weathering.
- Construction activities involve cutting and blasting rocks, increasing their exposure to weathering agents.
- Deforestation removes the protective vegetation cover, exposing rocks and soil to wind, water, and temperature changes.
- Industrial pollution can cause acid rain, which speeds up the chemical weathering of rocks, especially limestone and marble.
Thus, although weathering is a natural process, human activities can significantly increase its rate.
