Which category includes fossil fuels and minerals as examples?

• A. Renewable natural resources
• B. Perpetual natural resources
• C. Nonrenewable
• D. Commodity

Answer: (C)

The main idea tested is how resources are classified by how quickly they can be replenished. Fossil fuels and minerals are nonrenewable resources because they form over extremely long geological timescales and there is only a finite amount available. Once we extract and use them, they aren’t replenished fast enough to meet human demand. Renewable natural resources, like sunlight or wind, can replenish over time, and perpetual resources (in practice) are effectively inexhaustible on human timescales, which is why fossil fuels and minerals don’t fit those categories. While they can be traded as commodities, the category that best describes them as a group is nonrenewable.
