Safeopedia explains Weathering
Weathering can also be called erosion as material such as rock is slowly eroded over time as it is gradually broken down by the process of weathering or the effects of weather. Most land masses are affected by weathering, and there are different kinds of weathering that affect land masses. There is physical weathering, which involves purely mechanical breakdown of materials, as with abrasion or wetting and drying, and there is also biological weathering, which involves chemical breakdown of material due to physical or chemical agents from a biological organism.
