Which of the following best describes nonrenewable resources?

Nonrenewable resources are best described as those that do not regenerate after use. This means that once they are depleted, they cannot be replenished naturally within a human timescale. Examples include fossil fuels, such as coal, oil, and natural gas, as well as certain minerals and metals.

Understanding the nature of nonrenewable resources is crucial in discussions about sustainability and environmental conservation, as reliance on these finite resources can lead to scarcity and ecological impacts as they are mined, extracted, or consumed. It distinguishes them from renewable resources, which are naturally replenished over short timeframes, and emphasizes the need for careful management and transitional strategies towards more sustainable energy and material systems.
