* Renewable resources: Resources that replenish naturally over a relatively short period of time, such as solar energy, wind energy, hydropower, and biomass.
* Non-renewable resources: Resources that are finite and take millions of years to form, such as fossil fuels (coal, oil, natural gas), minerals, and metals.
Natural resources are essential for our survival and well-being, providing us with food, water, energy, materials for building and manufacturing, and many other things.
