December 6th‚ 2012 BIOL-4060 Abstract: Our planet continues to be influenced by geological processes which help make the way look it is today‚ some of these account for weathering. Weathering is essentially the breakdown of rocks‚ soils and minerals in water and land through interaction with the Earth’s atmosphere. Weathering occurs by means of two processes‚ physical and chemical. Chemical weathering involves atmospheric chemicals in breakdown of rocks and solids. Physical weathering occurs
