📚 Quick Study Guide
Fossil fuels like coal, oil, and natural gas are formed from ancient organic matter over millions of years. Their extraction and combustion are major sources of energy but also significant environmental concerns.
- 🌍 Fossil Fuel Formation: Formed from decomposed plants and animals under heat and pressure over geological time.
- ⛏️ Extraction Methods: Includes drilling (oil/gas), mining (coal), and fracking. Each method has distinct environmental risks.
- 🏭 Combustion Byproducts: Burning fossil fuels releases greenhouse gases (like CO2, methane) and air pollutants (SO2, NOx).
- 🌡️ Climate Change Link: Increased greenhouse gases trap heat, leading to global warming and altered climate patterns.
- 💧 Environmental Impacts: Extraction can cause habitat destruction, water pollution (oil spills, fracking fluids), and land subsidence.
- 💨 Air Quality: Combustion releases particulate matter and gases contributing to smog, acid rain, and respiratory issues.
- 💡 Alternatives: Renewable energy sources (solar, wind, hydro) offer cleaner alternatives to reduce reliance on fossil fuels.
