How is it formed?
Millions of years ago plants died and they formed layers at the bottom of the ground. Eventually water and dirt covered the plant remains for many years and were further down in the ground. This caused a lot of heat and pressure and it formed into a black rock what we call now coal.
Good or bad?
I think that the fossil fuel Coal is a good energy source to our world. Although coal might have some downsides, the positives outnumber the negatives.
- Supplies 40% of our electricity
- 4 billion dollars annually because of coal
- Without coal, no Industrial Revolution
- Lasts longer, any other fossil fuel
- Leading source of energy
