Answer :

Final answer:

Non-renewable resources are finite and take thousands of years to replenish. Their use is unsustainable.


Explanation:

Non-renewable resources are natural resources that exist in fixed amounts and can be used up. Examples include fossil fuels like petroleum, coal, and natural gas. These resources take thousands of years to replenish and are finite within human time frames. They are unsustainable, as their use far exceeds the rate at which they can be naturally replenished.
