Definition - What does Natural Resources mean?
Natural resources are materials that the earth produces and that humans use to make into other products. Since they occur naturally, humans cannot make them. Rather, we use and modify natural resources in ways that are beneficial to us.
Safeopedia explains Natural Resources
Natural resources can be classified as being either biotic or abiotic. Biotic natural resources come from living things or organic materials. These include plants, animals and fossil fuels. The three fossil fuels are coal, oil and natural gas. Abiotic natural resources come from non living materials, such as water, the sun and the air.
