Natural Resources
Natural resources are materials from the Earth that people use — water, air, soil, minerals, and fuels. A key skill on the test is sorting these into two groups: renewable resources that nature replaces, and nonrenewable resources that run out. This lesson makes the distinction clear.
Renewable Resources
Renewable resources are replaced by nature about as fast as we use them, so they do not run out if managed well. Sunlight, wind, and flowing water are always available. Trees and crops can regrow. Because they refill naturally, renewable energy sources like solar, wind, and hydroelectric power are attractive for the long term, and they usually produce little pollution.
Nonrenewable Resources
Nonrenewable resources exist in limited amounts and take so long to form that they cannot be replaced on a human timescale. The main examples are fossil fuels — coal, oil, and natural gas — which formed over millions of years from ancient organisms. Once we burn them, they are gone, and burning them releases pollution and carbon dioxide. Minerals and metals are also nonrenewable.
Sorting Resources
The test often gives a resource and asks which group it belongs to. Ask one question: does nature replace it quickly? Sunlight, wind, water, and growing plants are renewable. Coal, oil, natural gas, and mined metals are nonrenewable. Conservation — using resources wisely and reducing waste — helps both kinds last longer and reduces harm to the environment.

A Routine for Resource Questions
- Renewable = replaced quickly by nature (sun, wind, water, plants).
- Nonrenewable = limited and slow to form (coal, oil, gas, metals).
- Fossil fuels are nonrenewable and release pollution when burned.
- Conservation makes resources last and protects the environment.
Practice
- What is a natural resource?
- Is solar energy renewable or nonrenewable?
- Name one fossil fuel.
- Are fossil fuels renewable or nonrenewable?
- Why are renewable resources attractive for the long term?
- What does conservation mean?
Answers
- A material from the Earth that people use.
- Renewable.
- Coal, oil, or natural gas.
- Nonrenewable.
- They are replaced naturally and produce little pollution.
- Using resources wisely and reducing waste.
