Question

Name any three fossil fuels.

Answer 1

Hint: A fossil fuel is a fuel that is produced by natural processes, such as anaerobic decomposition of buried dead organisms, and contains organic molecules that were formed during ancient photosynthesis and release energy when burned. These species, as well as the fossil fuels they produce, are typically millions of years old, if not more than $650$ million years old.

Complete answer:
For more than a century, fossil fuels have provided the majority of the energy needed to power our vehicles, run our businesses, and keep our homes lit. Oil, coal, and gas also supply about $80\mathrm{\%}$ of our energy needs today. From air and water pollution to global warming, using fossil fuels for energy has taken a huge toll on humanity and the climate.

Since they were made from the fossilised, buried remains of plants and animals that lived millions of years ago, coal, crude oil, and natural gas are all classified as fossil fuels. Fossil fuels have a lot of carbon in them because of their sources.

Crude oil : Petroleum, also known as crude oil, is a liquid fossil fuel made primarily of hydrocarbons (hydrogen and carbon compounds). Oil can be found in underground lakes, sedimentary rock fractures, crevices, and pores, and tar sands on the surface of the earth. In the case of tar sands oil and oil shale, it's accessed by fracking on land or at sea, or strip mining.

Coal : Coal is a dense, carbon-rich rock that is classified into four types based on their carbon content: lignite, sub-bituminous, bituminous, and anthracite. Sub-bituminous or bituminous coal accounts for almost all of the coal consumed in the United States. These coal varieties, which can be found in abundance in Wyoming, West Virginia, Kentucky, and Pennsylvania, are in the middle of the pack in terms of carbon content and heat energy production.

Natural Gas : Natural gas, which is mainly methane, is classified as conventional or unconventional depending on where it is located underground. Natural gas can be found in porous and permeable rock beds or blended into oil reservoirs, and it can be accessed using conventional drilling techniques.

Note: Exploration, refining, and transportation of underground oil, gas, and coal deposits wreak havoc on our environments and habitats. The fossil fuel industry rents vast swaths of land for infrastructure including wells, pipelines, and access roads, as well as refining, waste storage, and disposal facilities.
