Whetering, often referred to as "weathering," is the process by which rocks and minerals are broken down into smaller particles or altered in composition due to various environmental factors. This can occur through physical processes, such as freeze-thaw cycles, or chemical processes, such as oxidation and hydrolysis. Weathering is a crucial part of the rock cycle and contributes to soil formation and landscape changes. It plays a significant role in shaping the Earth's surface over time.
