📚 Topic Summary
Fossil fuels, like coal, oil, and natural gas, are formed from the remains of ancient plants and animals that lived millions of years ago. Over time, these organic materials were buried under layers of sediment and subjected to intense heat and pressure, transforming them into the carbon-rich fuels we use today. These fuels are a major source of energy, powering our homes, transportation, and industries, but their use also contributes to environmental challenges.
