Fossil Fuel - GCSE Physics Definition

Fossil fuels are natural energy sources formed from the remains of ancient plants and animals, buried and subjected to heat and pressure over millions of years. Common examples include coal, oil, and natural gas. They are called "fossil" fuels because they originate from decomposed organic matter. These fuels are burned to release energy, which is used for electricity generation, heating, and powering vehicles. However, the combustion of fossil fuels releases carbon dioxide and other greenhouse gases, contributing to global warming and climate change. Their finite nature and environmental impact make the search for renewable energy sources increasingly important.
