(repeat, as this is a common misconception)
Fossil fuels are nonrenewable resources. They are formed over millions of years from the remains of dead plants and animals that have decomposed under the Earth's surface. Once these resources are depleted, they cannot be replenished within a human lifespan. Examples of fossil fuels include coal, oil, and natural gas.
