Fossil fuels are composed primarily of carbon, along with hydrogen and smaller amounts of other elements.

Fossil fuels are formed from the remains of ancient plants that have been buried and subjected to heat and pressure over millions of years.

Oil is formed from the remains of marine organisms, such as plankton and algae, that have been buried and subjected to heat and pressure over millions of years.

Carbon dioxide is the primary greenhouse gas emitted by the burning of fossil fuels. It traps heat in the atmosphere, contributing to global warming.

Exposure to air pollution from fossil fuels has been linked to an increased risk of asthma, chronic bronchitis, heart disease, and cancer.

Extraction is the general term used to describe the process of removing fossil fuels from the Earth, which can involve mining, drilling, or fracking.

Coal is the primary fossil fuel used for electricity generation worldwide, although its use is declining in many countries due to concerns about its environmental impact.

Combustion is the process of burning fossil fuels to release heat energy, which can be used to generate electricity or power engines.

Oil is the primary fossil fuel used for transportation, as it is the main component of gasoline and diesel fuel.

Refining is the process of removing impurities from fossil fuels, such as sulfur and nitrogen, to make them suitable for use in various applications.

Natural gas is the primary fossil fuel used for heating homes and buildings in many parts of the world, as it is a clean-burning fuel that produces relatively low emissions.

Drilling is the primary method used to extract natural gas from underground reservoirs. It involves boring a hole into the Earth's crust and using specialized equipment to bring the gas to the surface.

Oil is the primary fossil fuel used for the production of plastics and other synthetic materials, as it is a rich source of hydrocarbons that can be converted into various chemicals.

Drilling is the primary method used to extract oil from underground reservoirs. It involves boring a hole into the Earth's crust and using specialized equipment to bring the oil to the surface.

Natural gas is the primary fossil fuel used for the production of fertilizers, as it is a source of nitrogen, which is an essential nutrient for plant growth.
