Coal

===Coal has been a useful resourc **e. It is primarily burned for the production of electricity and/or heat, and is also used for industrial purposes, such as refining metals. Its mostly used in the eastern part of the United States** === ===Coal is a fossil fuel formed from the decomposition of organic materials that have been subjected to geologic heat and pressure over millions of years. Coal is considered a nonrenewable resource because it cannot be replenished on a human time frame.===

The atomic number is 6
**The atomic Mass is 1660K. The activities involved in generating e****lectricity from coal include mining, transport to power, and burning of the coal in power plants. Initially, coal is extracted from surface or underground mines. The coal is often cleaned or washed at the coal mine to remove impurities before it is transported to the power plant—usually by train, barge, or truck. Finally, at the power plant, coal is commonly burned in a boiler to produce steam. The steam****is run through a turbine to generate electricity.** ===Although power plants are regulated by federal and state laws to protect human health and the environment, there is a wide variation of environme **ntal impacts associated with power generation technologies.** === Coal moves trains!!!!!

 * Coal is destroying our atmosphere and is making the ozone layer bigger, so if we keep creating our electricity from coal, we will eventually be swept away from the solar wind because we ha****ve no atmosphere to** **protect** **us. Most of the worlds electricity is created by coal.**

 * Coal can be found around 200 feet under ground, which is a relatively short distance compared to other resources. To get coal people use the method of deep mining.**


 * Anthracite: A hard coal with high heat and a high concentration of carbon.**
 * Bituminous: A softer coal with less heat and a lower concentration of carbon.**
 * Coke: A fuel created by burning coal without air.**
 * Lignite: A brown coal that has less heat and lower concentration that both Anthracite and Bitiminous.**


 * Coal has been used for energy since the 1800's. In the beginning of coal mining, men would tunnel, dig, and manually extract coal in carts. Now coal mining has long open cut wall mines. They materials they use are draglines, trucks, conveyors, jacks, and shearers.**
