Mechanical weathering is the process of breaking big rocks into little ones. This process usually happens near the surface of the planet. Temperature also affects the land. The cool nights and hot days always cause things to expand and contract. That movement can cause rocks to crack and break apart.
Regarding this, what is the result of weathering?
Weathering and erosion are closely related concepts. As weathering occurs, breaking up the rock, it can be transported through erosion. There are two categories of weathering processes: Physical and Chemical. Although they are two very different processes, they work together to break down rocks and minerals.
How does weathering and erosion affect humans?
Humans can affect weathering (breaking down of rock/soil) in several ways. Humans cause increases in acid rain and pollution, which increase the amount of weathering agents in the air and water, and then on land.
