* Natural Resources: These are materials or substances occurring in nature that can be used for economic gain. They are classified into:
* Renewable Resources: These resources can replenish naturally over a relatively short period, like solar energy, wind energy, and timber.
* Non-Renewable Resources: These resources are finite and take millions of years to form. Examples include fossil fuels (coal, oil, natural gas), and minerals.
* Capital Resources: These are man-made resources used in the production of goods and services. Examples include machinery, factories, and buildings.
* Human Resources: This refers to the skills, knowledge, and abilities of people. It is also sometimes called "labor".
The environment is the source of natural resources, not capital or human resources.
