Which category includes coal, oil, and natural gas that cannot be replaced quickly?

• A. Renewable Resources
• B. Groundwater
• C. Non-Renewable Resources
• D. Weather

Answer: (C)

The concept here is that some resources cannot be replenished quickly. Coal, oil, and natural gas are fossil fuels formed over millions of years from ancient plants and microscopic organisms buried underground under heat and pressure. Humans are using them far faster than they form, so there isn’t enough to meet near-term needs. That makes them non-renewable resources. In contrast, renewable resources like sunlight, wind, and flowing water can be replenished on human timescales, which is why they’re not in this category. Groundwater isn’t the same kind of clear-cut label in everyday usage, and weather isn’t a resource category. So the correct category is non-renewable resources.
