Which of the following fuels is/are fossil fuels?

I. Coal

II. Petroleum

III. Wood

The correct answer is I and II.

Key Points

• Coal is a fossil fuel that is formed from the remains of ancient plants and animals, subjected to intense heat and pressure over millions of years.
• Petroleum, also known as crude oil, is a liquid fossil fuel formed from the remains of marine microorganisms that lived millions of years ago.
• Both coal and petroleum are extensively used as energy sources due to their high carbon content and energy density.
• Fossil fuels are non-renewable resources, meaning they are finite and will eventually be depleted.

Additional Information

• Wood is not classified as a fossil fuel; it is considered a biomass fuel, which is renewable and can be replenished over time.
• Formation of Fossil Fuels: Fossil fuels like coal and petroleum are formed from the anaerobic decomposition of ancient organic matter over geological time.
• Environmental Impact: The combustion of fossil fuels releases greenhouse gases, such as carbon dioxide (CO2), which contribute to global warming and climate change.
• Alternative Energy Sources: Due to the negative environmental impact of fossil fuels, there is a growing emphasis on renewable energy sources such as wind, solar, and hydroelectric power.
• Energy Transition: Many countries are investing in the energy transition from fossil fuels to sustainable energy sources to mitigate environmental degradation and ensure energy security.
