Coal is a combustible rock mainly composed of carbon along with variable quantities of other elements, mostly hydrogen, sulphur, oxygen and nitrogen. Coal occurs as layers, called coal beds or coal seams, that are found between other sedimentary rocks. Coal is slightly denser than water but less dense than most of the rocks of the Earth's crust ...

Question 8: Explain the process of formation of petroleum. Answer: Petroleum is formed by the burial of aquatic plants and animals below the sea bed. The marine animals and plants died thousands of years ago and settled down in the bottom of the sea. In anaerobic conditions, microorganisms decompose this organic matter.

Fossil fuels are nonrenewable sources of energy formed from the organic matter of plants and microorganisms that lived millions of years ago. The natural resources that typically fall under this category are coal, oil (petroleum), and natural gas. This energy (and CO 2) was originally captured via photosynthesis by living organisms such as plants, algae, and photosynthetic bacteria.

Petroleum is a mixture of many substances such as gas, petrol, diesel, kerosene, lubricating oil, paraffin wax, etc. As these constituents serve different purposes, it is important to separate them, or in other words, refine the crude oil. This process of separation of various constituents of petroleum is called petroleum refining.

How crude oil is refined into petroleum products. Petroleum refineries convert (refine) crude oil into petroleum products for use as fuels for transportation, heating, paving roads, and generating electricity and as feedstocks for making chemicals.. Refining breaks crude oil down into its various components, which are then selectively reconfigured into new products.
