What are fossils fuels ?
Answers
Answer:
Fossil fuels are formed by natural processes of decomposition of dead and buried plants, animals and other organism. They got buried under oceans and layers of earth many millions of years ago and with time, high pressure and high temperature they formed fossil fuels.

HI MATE !
Here is your answer :- ⬇️ ➨
- A fossil fuel is a fuel formed by natural processes, such as anaerobic decomposition of buried dead organisms, containing organic molecules originating in ancient photosynthesis that release energy in combustion.
- Fossil fuels, including coal, oil and natural gas, are currently the world's primary energy source. Formed from organic material over the course of millions of years, fossil fuels have fueled U.S. and global economic development over the past century. Yet fossil fuels are finite resources and they can also irreparably harm the environment. According to the U.S. Energy Information Administration, the burning of fossil fuels was responsible for 76 percent of U.S. greenhouse gas emissions in 2016. These gases contribute to the greenhouse effect and could lead to potentially catastrophic changes in the Earth’s climate. Technologies such as Carbon Capture and Storage (CCS) may help reduce the greenhouse gas emissions generated by fossil fuels, and nuclear energy can be a zero-carbon alternative for electricity generation. But other, more sustainable and less risky solutions exist: energy efficiency and renewable energy.
TYPES OF FOSSIL FUELS :- ⬇️ ➨
Oil -
Oil is the world’s primary fuel source for transportation. Most oil is pumped out of underground reservoirs, but it can also be found embedded in shale and tar sands. Once extracted, crude oil is processed in oil refineries to create fuel oil, gasoline, liquefied petroleum gas, and other nonfuel products such as pesticides, fertilizers, pharmaceuticals, and plastics.
Coal -
Coal is primarily used to generate electricity and is responsible for 30 percent of the electric power supply in the United States in 2017 (down from 39 percent in 2017 and 50 percent in 2007). The United States produces around 11 percent of the world’s total with Wyoming, West Virginia, Pennsylvania, Illinois, and Kentucky leading in production. China is the global leader in coal production, responsible for 48 percent of world supply (as of 2015).
Natural Gas -
Natural gas generates an increasing share of
U.S. electricity and now represents close to a
third of the country's energy use. It is most
commonly used to produce heat or electricity
for buildings or industrial processes; less than
three percent of U.S. natural gas is used as a
transportation fuel, typically for bus fleets. The
United States produces around 17.6 percent of
the world’s natural gas and consumes about
21.6 percent of it (as of 2015). Natural gas is
most commonly transported by pipeline, which
makes Canada the key exporter to the United
States, while Russia remains the main supplier
for much of Europe. Increasingly, however,
natural gas is being transported by ship in a
liquefied form (LNG) to meet greater global
demand for the fuel.
