Minerals
Minerals play a very important part in society, in terms of both the economy and health. People use minerals to stay healthy by means of food supplements. Minerals are also present in foods that people eat. Minerals also play a very important part in the mining industry and in the economy. According to the Mine-Engineer.com (2011) Website, the mining industry in the United States includes 140,000 employees.
Metallic minerals can be melted to obtain new products. Two examples of these are iron and copper. They are usually associated with igneous rocks and are generally used to manufacture products that can be used for various purposes. Such products might include wire or wheels. Non-metallic minerals are not melted to yield new products. Two example include salt and marble, which can be used for flavoring food and building material, respectively.
Mining
1.
Minerals are extracted and processed during the mining process. Minerals are extracted from the earth in their crude form, after which they are processed by means of industrial processes to refine them and make them available for commercial use. Copper ore, for example, is melted down to separate the metal from the rock and earth with which it is mined.

According to Mining.Net (2011), three types of mining include dredging, surface mining, and underground mining. Dredging is done close to a good water source and is generally used when large volumes of low-value product are extracted. Surface mining occur as open-cast or open-pit mining, depending on whether soft- or hard-rock mining is at issue. Underground mining occurs by means of vertical shafts or roadways that are inclined downwards. Two access routes are used for miners and materials, respectively.
3.
There are several potential impacts that mining can have on the environment (Montana State University, 2004). These include acid mine drainage formation, erosion and sedimentation, chemical releases, fugitive dust emissions, natural habitat modification, and pollution to surface and groundwater. Mine managers need to be aware of these potential effects in order to mitigate them and to create an optimal balance between mining profit and environmental sustainability.

Also, careless people with guns shot the condors at will; and when ranchers put out poison to kill wolves and grizzly bears the condors then fed on those carcasses and were poisoned as well. In 1937 the U.S. Congress set aside a refuge for the condors in Santa Barbara County and in Ventura County in 1947, trying to protect these great birds, Peeters explains (p. 114). By 1987, there were
" (Sukumaran, 2004) Mutation is what results in the difference and may be utilized as a measure of the time that has elapsed since separation of the species from the common ancestor during evolution. This is a method of "inferring the divergence of time of clades from a common ancestor by means of gene/protein sequencing" and has been termed 'molecular dating'. The process is one in which there is a
The natural environment provides students with a calm and quiet place to unwind from the noises of the classroom. It nurtures and supports animal-life all year round. This is critical for areas where commercial and residential development is reducing most natural areas. Wildlife especially needs help during the cold and snowy months. Students can also see how it benefits the environment. It also helps connect students to the world
Sandia Mountains Environmental History of Sandia Mountains The view from the top of Sandia Peak is breathtaking. Showing off some of Nature's finest work, the Tramway glides along the cable climbing the rugged Sandia Mountains presenting spectacular views of the Rio Grande Valley and nearby Sandia Crest. Even though you're just a few miles from Albuquerque, the 15 minute tram ride has taken you far away from the everyday world. As your
Environmental Hazards as a Consequence of Crude Oil/Natural Gas Exploration, Transportation, Refining and Storage Ever since crude oil was first successfully drilled in the U.S. In Titusville, Pennsylvania, in 1859, the demand for oil has only been increasing over the years in countries all over the world. (Camden, 1883) Crude oil, from which various petroleum products are obtained, is a naturally occurring hydrocarbon component found trapped in rocks below the
