People also weather rocks through many of their activities. To build roads, they sometimes have to blast with dynamite the large rocks along mountainsides. These rocks are broken into fragments.
They dig tunnels for mining operations. They dig out large rocks and sand in large open pits called quarries. The rocks and sand that they quarry are used for construction.
People build factories to manufacture the things they need. Factories release some chemicals which, when combined with water in the atmosphere, produce acid rain. Acid rain can eat into rocks and break them.
