Question

choose the correct answer. if a natural resource is replaced at a constant rate, regardless of how much is used, it is considered to be ____________. non - sustainable non - depletable non - renewable

Explanation:

• Non - sustainable: Refers to a situation where resources are used at a rate that cannot be maintained over time. It does not imply a constant replacement rate.
• Non - depletable: Means that the resource cannot be used up. This is often used for resources like solar energy (in a practical sense for the time - scale of human existence), but the key here is the "constant rate of replacement" aspect.
• Non - renewable: Usually refers to resources like fossil fuels that are formed over very long geological timescales and are not replaced at a rate that can keep up with human consumption.

A non - depletable resource is one that is replaced at a constant rate regardless of usage. For example, solar energy (in the context of the Earth's lifespan relevant to human activities) is considered non - depletable as the sun's energy is constantly radiated to the Earth at a relatively constant rate (on a human - relevant timescale) and is not depleted by human use of solar energy technologies.

Answer:

non - depletable
