What is a nonrenewable substance?

Answer 1

A non renewable resource is something that can't be made again in nature or takes a very long time to replace. Such as metals because they don't grow under ground. Or coal because it takes years to make.

Answer 2

Nonrenewable resources generally fall into the category of things that were here before Humans were and are disappearing and won't be returning anytime soon.

The most common examples are sources of energy (fossil fuels, fissionable uranium) and metals but those are only the nonliving examples.

Fossil fuels include these.

1. Oil
2. Coal
3. Natural gas

Metals, some of which are already nearly gone, include these.

1. Antimony
2. Indium
3. Silver
4. Uranium
5. Gold

The related link to a BBC article give a projected timeline for depleting these plus the depletion of various environmental components, including land for agriculture, coral reefs and rain forests.

Of course, the extinction of many species of plants and animals may or may not be considered a "resource," but that happens pretty much every day.

A:Non renewable sources are sources such as gasoline that will not "replenish. For instance once you use all of a non-renewable source it is gone forever. Some renewable sources like trees are able to keep growing. A:Non-renewable resources are types of resources that can be used once.

• A Nonrenewable source is something that you use once and cannot use it again.

A:a non-renewable source is a natural resource that cannot be produced, re-grown, re-used for further on a scale which can sustain its consumption rate.

Something like coal or oil. When it is used up, it is used up. Nothing is making new coal or oil. Trees would be a renewable resource- plant them, they grow new trees.
