where does petroleum occur

It is the most important of the fossil fuels. Petroleum occurs under the Earth's crust. It is believed to have formed due to the bacterial action of decomposition on marine animals and prehistoric forests inside the Earth, under conditions of high temperature and pressure. ..

Petroleum occurs in nature, trapped between two layers of impervious (non-porous) rocks, usually under the sea. Natural gas collects above the surface of petroleum..

Coal and Petroleum - Fossil fuels, like, coal, lignite, petroleum and natural gas are non renewable natural resources. Both have an organic origin and are called hydrocarbon fuels. Coal was formed in nature as a solid from the remains of the trees buried deep inside the earth, s..

When the key K is pressed, current starts flowing through the coil P and this increases the magnetic flux linked with P. Since S is very close to P, the magnetic flux linked with S also increases. Thus induced emf, hence induced current is produced in S. The direction of induced current in S is gi..

Petroleum is a dark, viscous, foul smelling liquid, a mixture of solid, liquid and gaseous hydrocarbons with traces of salt, rock particles and wat..

Coal and petroleum have organic origin, being decomposed plant and animal matter buried deep inside the earth. Coal is mined like any other mineral. The chief coal producing countries in the world are China, U.S.A., U.S.S.R., U.K., Germany, Poland, Australia and India. In India, coal is ..

Petroleum is brought to the surface by drilling a hole in the Earth's crust and sinking pipes deep down through the impervious cap rock. Natural gas first comes out under high pressure. Then, petroleum is pumped out, collected in tanks and transported, for further processing. ..

Sources of Hydrocarbons - Until the early years of the nineteenth century, only the plants and animals were the known sources of organic compounds. With the advent of the Industrial Revolution in Europe, fossil fuels like coal and petroleum gained prominence as the sources of organic comp..
