Which is classified as a renewable resource?

A.

natural gas

B.

coal

C.

water

D.

petroleum

Well, in a way all of them are renewable - just not in our life time (e. g. coal will be created again, but this is of no practical importance for us, as if we use up all the coal, we will have to wait a lot of generations to have access to coal again).

the only resource from the list that is renewable in a short time is water.
