Fossil Fuels and Their Impact

Fossil fuels like coal, oil, and natural gas were formed millions of years ago from decayed organic matter. Coal mainly comes from trees, while oil and gas originate from aquatic organisms. These fuels are crucial for energy and manufacturing but have environmental drawbacks, such as contributing to global warming and acid rain. As fossil fuels are finite, developing renewable energy sources is essential.

What are fossil fuels primarily formed from?

• Decaying plant and animal matter

• Volcanic ash

• Ocean water
