ATC Engineering Technology 2 Sustainability Practice Test

Renewable resources are defined as those resources that can be replenished naturally over time. This means that these resources are not permanently depleted when they are used. Instead, they can regenerate through natural processes, making them sustainable over the long term. Examples of renewable resources include sunlight, wind, rain, and biomass.

In contrast to this correct definition, the other options reflect characteristics of non-renewable resources or limited availability. Resources that are permanently depleted by use imply that once they are consumed, they are gone forever, which is contrary to the nature of renewable resources. Resources available in limited quantities suggest scarcity, which applies to non-renewable resources like fossil fuels and minerals. Lastly, resources that require non-renewable methods for usage implies dependence on finite resources, which contradicts the concept of renewal. Therefore, the focus on the ability of certain resources to naturally replenish themselves makes the selection of the definition that describes them as capable of being replenished over time the correct choice.
