Question

Which of the following is/are fossil fuels?
(A) Natural gas (B) Coal
(C) Petroleum (D) All of the above​

Answer 1

(D)All of the above.

Fossil fuels

Fossil fuels are produced using disintegrating plants and creatures. These fills are tracked down in the Earth's crust and contain carbon and hydrogen, which can be used for energy.

(A)Natural gas

• Natural gas is a fossil energy is found below the world's surface.
• This Flammable gas comprises many compounds, but the main component of natural gas is methane.

(B)Coal

• Coal is an impure type of carbon and is dark in color.
• It has been formed from the remaining parts of tremendous and thick woodlands of trees and plants which developed a long time back and were at last lowered under other sedimentary rocks.

(C)Petroleum

• It is called crude oil since they are a combination of hydrocarbons that are shaped from the remaining parts of creatures and plants  that lived a large number of years prior in a marine environment.

• More than a large number of years, the remaining parts of these creatures and plants were covered by layers of sand, residue, and rock. Intensity and strain from these layers transformed the remaining parts into what we presently call raw petroleum.

Therefore, all of the above are fossil fuels.

Answer 2

Answer:

The correct option is d) All of the above

Explanation:

• Fossil fuel is a hydrocarbon-containing substance collected and used as a fuel that forms naturally in the crust of the earth from the remnants of dead and decaying plants and animals.
• Various processes are continually taking place on earth. The results of these slow processes take millions of years to emerge.
• Over time, the layer of soil on the earth's surface is gradually covered by newer layers, which are deposited on top of the preceding one.
• Between these layers, the remnants of dead and rotting plants and animals become trapped.
• The compression of sediments can result in the creation of sedimentary rocks.
• These layered rocks are fragile and frequently contain the imprints of dead plants and animals that become caught between them.
• These imprints are known as fossils.
• Fossil fuels are so-called because they are formed when the dead remnants of living creatures become trapped between soil layers and are exposed to heat and pressure over millions of years to form fuels.
• Fossil fuels are limited, non-renewable, and exhaustible energy sources.
• When used inappropriately, they might get exhausted.
• The production of these fuels contributes to the natural carbon cycle.
• Natural gas, petroleum, and coal all are examples of fossil fuels.
