Coal is formed from deposits of organic material, plants and animals, that get compressed together in the Earth over many hundreds of thousands of years. It's mainly Carbon, if it gets compressed even longer with more pressure it becomes a diamond.

Coal is made from giant tree-like ferns that lived 350 million years ago during a period called Carboniferous period. Carboniferous means carbon-bearing-- because this is when most of the coal was made. This period pre-dates dinosaurs!

When these giant ferns that lived in swamps died, they fell into the swamp, and because things don't decompose very well in a swamp (due to low oxygen), they accumulated. Over looooong periods of time, these material were compressed until all the other elements were queezed out until mostly carbon remained-- and TADA! you have coal. This process is called carbonization.

Some coal has a lot of impurities in them. These coal (called bituminous coal) release lots of pollutants when burned. Coals with less impurities have more carbon in them (anthracite coal), so they burn cleanier and hotter, so they are more valuable.

Other fossil fuel, such as crude oil (petroleum) and natural gas are remains of microorganisms that lived in shallow seas and lakes.

This question is a little easier,but getting older I can't remembetr it all.but Its basically plant matter buried for Hundreds of thousands of years if not millions and where you find coal you find shale..don't remember why?but anyway over that time tremendous pressure and heat turn it to coal and theres different types of coal too 3 I believe ? I worked in the coal mines for a short time and have found numerous imprints of plants in the shale deposits. And after A few more million years of heat and pressure comes........DIAMONDS !

I personally hung around the "Men of the Deeps", Coal Miners, from Nova Scotia Canada, (Coal Miners/Singers). I managed to visit the Mines and learned much. I also got a few fossils from the mine. One looks like a tree branch, the other a fern leaf One fossil looked like a bird, none I have ever seen before. The coal there is vegetation & other life forms that exisited millions of years ago, that came from another Continent that broke off billions of years ago to form the Island of Cape Breton, Nova Scotia. The vegetation is from a Tropical area far south of the world. The coal is formed by compression of this matter over time, and this is why it is called Fossil fuel. The mine where I got my fossils from came from 2300 kilometers below sea level. I can explain all of this information in a more scientific manner, but I thought this was the easiest to understand and a fun way to share to you why traveling and exploring these places first hand is important.
If you can, the Men of the Deeps have a couple of CD's out, they performed concerts all over Canada and Washington D.C. They are awsome entertainers as well as being Miners. Outstanding music!! Well worth checking out.

when things die and then decompose into the earth layer after layer after layer of dead living things the earth putts pressure on te layers and in 100 of years or more they turn into coal
