Organic material is the remains of once-living organisms, such as plants, animals, and microorganisms. It is the primary source of energy for all life on Earth, and it is also used to produce a variety of products, including food, fuel, and clothing.

Organic material from which coals forms:

The organic material that forms coal is derived from plants that lived millions of years ago. These plants were buried under layers of sediment and subjected to heat and pressure over time, which caused them to decompose and transform into coal. The type of coal that is formed depends on the age, composition, and conditions under which the organic material was buried.

Organic material from which petroleum and natural gas forms:

The organic material that forms petroleum and natural gas is derived from microscopic plants and animals that lived in ancient oceans and lakes. These organisms died and sank to the bottom of the water bodies, where they were covered by layers of sediment. Over time, the heat and pressure from the overlying sediments caused the organic material to decompose and transform into petroleum and natural gas.

Difference:

The main difference between the organic material from which coals forms and petroleum and natural gas forms is the type of organisms from which they are derived. Coals are formed from the remains of land plants, while petroleum and natural gas are formed from the remains of marine organisms. Additionally, the conditions under which the organic material is buried and transformed are different for coals and petroleum and natural gas. Coals are formed under conditions of high temperature and pressure, while petroleum and natural gas are formed under conditions of low temperature and pressure.
