A non-renewable resource is a natural resource that cannot be re-made or re-grown. Often fossil fuels, such as coal, petroleum and natural gas are considered non-renewable resources, as they do not naturally re-form at a rate that makes the way we use them sustainable. This is as opposed to natural resources such as timber, which re-grows naturally and can, in theory, be harvested sustainably at a constant rate without depleting the existing resource pool. In this sense, all mined resources, stone, metals, uranium, and various other materials and minerals should be considered non-renewable.

Non renewable resources are sources that can't be recreated, there is a fixed amount of them in the environment. Ex. coal, and petroleum.

i believe non renewable resources are things like coal and oil petrolium or uranium, things that are found in the earth used as energy resources that once the are gone, they are gone- cannot be replenished my man, only time and nature can create these things.

non-renewable resources are things like coal. once you burn it you can't get it back. Renewable resources are things like paper you can recycle it.

those sources of energy which when exhausted need a very long time to be replaced or are not at all replaced. that is simply they can not be renewed. ex coal, petroleum products.
