Question

Formation of coal in detial?

Answer 1

HeyAaa!!

Here is ur Answer ^_^

The energy in coal comes from energy that was stored in giant plants that lived hundreds of millions of years ago in swamp forests, even before the dinosaurs! When these giant plants and ferns died, they formed layers at the bottom of the swamps. Water and dirt began to pile up on top of the dead plant remains.

Hope It Helps.

━━━━━━━━━━━━━━━━━━━━━━━━━━

$\implies$Coal:— Coal is a fossil fuel made of carbon, hydrogen, and oxygen. It is found inside the earth in the form of deposits.

The formation of coal involves high temperature and pressure. When plants and trees die, their remains get buried in the earth. This is converted into coal over hundreds and thousands of years.

$\implies \large{ \green{ \sf{Formation \: Of \: Coal:—}}}$

Coal was formed some 300 million years ago, when trees and plants in the forests got buried under the earth's surface as a result of earthquakes, cyclones, and other natural disasters. There are hot conditions, absence of air; as a result hydrogen and oxygen were removed from wood, leaving behind carbon. Due to high temperature and high pressure, the carbon changed into a stone-like residue called coal.

This slow process of changing of wood into coal by numerous heating and pressure inside the earth's surface is called carbonisation.
