Final answer:
Humans increase the rate of chemical weathering through activities such as mining, construction, and agriculture.
Step-by-step explanation:
Humans increase the rate of chemical weathering mainly through their activities such as mining, construction, and agriculture.
For example, mining activities expose rocks to the air and water, facilitating the process of chemical weathering. Construction activities often involve the use of materials that are susceptible to chemical weathering, such as limestone.
Agriculture contributes to chemical weathering through the use of fertilizers that contain chemicals that can react with rocks and minerals.
