Physical Weathering Processes

The video tutorial by Professor Dave explains the process of weathering, a key aspect of mineralogy. Weathering is divided into physical and chemical types. Physical weathering involves mechanical breakdown of rocks, while chemical weathering involves chemical alterations. The video delves into physical weathering, highlighting mechanisms like freeze-thaw in temperate climates and mineral growth in arid regions. Biological factors such as tree roots and animal burrowing also contribute. The formation of joints in rocks accelerates weathering. The tutorial concludes with a transition to chemical weathering.
