The products and materials we use from day to day are made from Earth's natural resources. A natural resource is something that is found in nature and can be used by people. Earth’s natural resources include light, air, water, plants, animals, soil, stone, minerals, and fossil fuels. People need some natural resources to stay alive. They use others to make their lives better.
Natural resources from the Earth fall into three categories: renewable, non-renewable and inexhaustible.
