What is the meaning of non renewable resource?

Answer 1

A resource that can't be used again!

Nonrenewable resources are resources which take thousands of years to form, like coal, oil, natural gas, uranium etc.

Any natural resource that cannot be remade or reproduced once it is used up is 'non-renewable'.

It means that something can't be used again.

Answer 2

A non-renewable resource is a natural resource which cannot be produced, grown, generated, or used on a scale which can sustain its consumption rate. These resources often exist in a fixed amount, or are consumed much faster than nature can create them
