__**Coal** __ is a **brown ** <span style="font-family: Georgia,serif;">or **black** nonrenewable rock that can be burned and ignited. When coal is burned, it provides a useful amount of heat. Coal is also used in pharmaceuticals, dyes, fertilizer, and other products. Coal was formed by partially decayed plant matter called //peat// over millions of years ago. The process peat goes through to turn to coal is called //coalification.// Coal contains mostly the elements carbon, hydrogen, nitrogen, oxygen, and sulfur. Coal was very in fueling the Industrial Reveloution, a period of rapid development in the 1700's and 1800's. Now, the countries of the world use 6 1/2 billion tons of coal, the US using 1/6 of this.

<span style="font-family: georgia,serif;">The reason I chose this video is because it shows the process of coal in a refinery. It shows the coal brought to the refinery by trains, then brought by a series of convayor to be pulverized. Then the coal is placed into a large furnace which turns the water into steam. Then after the generator spins, a flow of electricity is conducted. Then it's finally sent to the station. Transformers then are sent to the transition lines. One thing I leared is that the water used to create steam is condensed back into water and reused.

<span style="font-family: Georgia,serif;">Coal is a solid fossil fuel that is found under ground. One, disadvantage is that it's hard to transport. Another one, is that it causes deaths. The last one is that it's responsible for globel warming. An advantage is it is easy to find. Another is that it's found in about 50 countries. The last one is that 4.3 billion tons of coal was produced in 2004.
