Nonrenewable resources are described as?

• A. Natural resources found only on land
• B. Resources that are replaced regularly
• C. Renewable resources
• D. Resource that cannot be replaced; once they are used, they are gone forever

Answer: (D)

Nonrenewable resources are materials that exist in fixed amounts and take geological time to form. Because they accumulate over millions of years, they aren’t replenished on human time scales. Once you extract and use them, there isn’t a quick way to replace what’s gone, so they can be depleted and essentially disappear as a usable resource. This is why the description that they cannot be replaced and are gone forever after use fits best. In contrast, renewable resources can be replenished naturally or quickly, which is why they’re categorized differently.
