Question

how do renewable and nonrenewable resources differ?
renewable resources are artificial.
nonrenewable resources are artificial.
renewable resources replenish within our lifetime.
nonrenewable resources replenish within our lifetime.

Explanation:

To determine the correct answer, we analyze each option:

• "Renewable resources are artificial" is incorrect because many renewable resources (e.g., solar, wind, water) are natural.
• "Nonrenewable resources are artificial" is incorrect as nonrenewable resources like coal, oil, and natural gas are natural and formed over millions of years.
• "Renewable resources replenish within our lifetime" is correct. Renewable resources (e.g., solar, wind, biomass) can be replenished relatively quickly, often within a human lifetime or a short geological time scale.
• "Nonrenewable resources replenish within our lifetime" is incorrect. Nonrenewable resources take millions of years to form and do not replenish within a human lifetime.

Answer:

C. Renewable resources replenish within our lifetime.
