How is coaled formed?

Answer 1

Coal was formed when massive amounts of vegetation died and fell into the swamps they grew in. This happened in the Carboniferous Period. Huge mats of waterlogged plant material were formed that resisted decay because there was very little oxygen there. Over millions of years, as the climatic and geologic conditions changed, these plant sediments were covered and compacted by other sediments, resulting in their conversion to coal.

Answer 2

Coal is formed by millions of little bugs and bacteria being squished.

It is used for energy because the animals and things that were compressed still have a form of energy in them because energy cannot be created or destroyed, only converted!!!

Answer 3

Through compression of dead organisms or through compression of burnt wood
