What is the definition of a nonrenewable resource?

• A. A resource that can be replaced continuously
• B. A resource that can be consumed indefinitely
• C. A resource with a finite supply
• D. A resource derived from sunlight

Answer: (C)

A nonrenewable resource is defined as a resource with a finite supply. This means that such resources are available in limited quantities and cannot be replenished on a human timescale once they are depleted. Examples of nonrenewable resources include fossil fuels (like coal, oil, and natural gas) and certain minerals. Over time, as these resources are extracted and consumed, they become less available, leading to concerns about sustainability and energy security.

In contrast, resources that can be replaced continuously or consumed indefinitely pertain more to renewable resources. Renewable resources, such as solar energy, wind energy, and biomass, can be replenished naturally in a relatively short time frame. The mention of a resource derived from sunlight specifically refers to solar energy, which also falls under renewable resources. Thus, only the option defining nonrenewable resources accurately captures the essence of their limited nature, highlighting the critical aspect of their finiteness.
