What do you mean by non-renewable resources ?

Answer»

These resources are those which once mined and used cannot be regenerate. As for example, coal and natural oil are such non-replenishable because once they are mined and use, they cannot be renewed. In fact, all mineral resources are limited in quantity, which can neither be increased nor renewed. Coal, mineral oil, iron-ore are non-replesihable resources.
