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

As is characteristic of many other heavily-mined minerals‚ high-grade copper areas are becoming increasingly rare as many of the largest and highest grade areas have been discovered and depleted by mining companies. It was common in the early 1900`s to find sites that had up to 30% copper; however‚ the

Positive Effects of Volcanos Volcanic activity has many positive impacts on both the natural physical environment and on socio-economic activity. Positive impacts include the creation of new land‚ the creation of valuable natural minerals and ores‚ and the enhancement of countries’ tourism potential. Creation of new land: Volcanic activity can result in the creation of new land‚ when material from within the earth’s crust is ejected in the form of molten liquid‚ then cools and solidifies to created
