Weathering Theories

Weathering refers to the process that breaks down rocks and minerals at the Earth's surface. There are two main theories: mechanical weathering and chemical weathering. Mechanical weathering involves physical forces, such as temperature changes or ice expansion, that fracture rocks without altering their composition. Chemical weathering, on the other hand, involves chemical reactions that change the mineral structure, often due to water, acids, or gases. Together, these processes shape landscapes, create soil, and influence ecosystems, demonstrating how rocks and minerals gradually evolve over time through natural forces.
