Detailed explanation-1: -It is formed when layers of decomposing plants and animals are subject to intense heat from the Earth and pressure from rocks. All this pressure, heat and millions of years turned the natural material into coal, petroleum and natural gas.
Detailed explanation-2: -Petroleum and natural gas are formed from the dead remains of marine organisms that were buried under the sea. High temperature, high pressure, and absence of air over million of years transform these dead organisms into petroleum and natural gas.
Detailed explanation-3: -Like other fossil fuels such as coal and oil, natural gas forms from the plants, animals, and microorganisms that lived millions of years ago. There are several different theories to explain how fossil fuels are formed. The most prevalent theory is that they form underground, under intense conditions.
Detailed explanation-4: -Definition: Natural gas is a mixture of gases which are rich in hydrocarbons. All these gases (methane, nitrogen, carbon dioxide etc) are naturally found in atmosphere. Natural gas reserves are deep inside the earth near other solid & liquid hydrocarbons beds like coal and crude oil.
