WebIt results only in smaller pieces of the parent rock at the same place. Physical weathering is caused by temperature changes, salt crystallization, frost and dust wedging, aeolian abrasion, unloading, and so on. Chemical weathering: The illustration below shows how rock can undergo physical weathering. How does chemical weathering happen? WebWind abrasion is the physical weathering of a rock from strong, turbulent winds, while deflation refers to wind actively removing loose particles. Wind erosion has a huge impact on shaping the Earth's surface as well as affecting our lives. It can affect crops and soils greatly disrupting agriculture and can also impact the air quality.
