Two important classifications of weathering processes exist â physical and chemical weathering; each sometimes involves a biological component. Mechanical or physical weathering involves the breakdown of rocks and soils through direct contact with atmospheric conditions, such as heat, water, ice and pressure.
Geologists recognize two categories of weathering processes. 1  Physical Weathering - disintegration of rocks and minerals by a physical or mechanical process. 2  Chemical Weathering - chemical alteration or decomposition of rocks and minerals. Although we separate these processes, as we will see, both work together to break down rocks and minerals to smaller fragments or to minerals more stable near the Earth's surface.Both types are a response to the low pressure, low temperature, and water and oxygen rich nature of the earthâs surface.
