Types of Fossil Fuels
Types of Fossil Fuels
Fossil fuels are formed from the buried remains of plants and animals over a period of millions of years. Coal, petroleum, and natural gas are examples of fossil fuels. Since fossil fuels are obtained from nature, they are referred to as natural resources. Natural resources can be divided into the following two types.
- Inexhaustible natural resources: These are resources of which there is a limitless supply. Sunlight and air are examples of inexhaustible resources.
- Exhaustible natural resources: These are resources whose supply is limited. Their overuse should, therefore, be avoided. Fossil fuels, forests, and wildlife are examples of exhaustible resources.
