- Coal
- Millions of years ago, dead plants fall into swamps.
- The dead plants accumulate at the bottom of the swamp and are acted on by heat and pressure which condense the plant matter.
- The plant matter eventually forms coal far underground.
- To get coal, it needs to be mined. In the Olden Days, Coal was mined manually, however now, due to health hazards, it is mined by machine.
- And that is how you get coal, which you use for energy, fuel and vital components in the steel and concrete industry.
- Natural Gas is formed the same way as Crude Oil and is used as a source of energy for heating, cooking and electricity generation. It is also used as a chemical feedstock in the manufacturing of plastics.
