| Non-renewable resources | Resources that can only be used once. Ex. burning fossil fuels such as coal and oil. |
| Region | An area of the earth's surface with similar characteristics that could be either physical or human. |
| Formal region | Usually has clear boundaries and a limited number of related characteristics such as Latin America and Europe. |
