Why is coal considered a nonrenewable resource? Check all that apply.Coal is burned to generate electricity.Coal power plants give off large quantities of smoke and ash.Coal forms so slowly that we could use up the supply that exists now. Coal is available in limited amounts.

Coal is nonrenewable because it takes a very long time to form, so people can use it faster than nature replaces it. It is also available in limited amounts. Therefore, “Coal forms so slowly that we could use up the supply that exists now” and “Coal is available in limited amounts” are correct. Burning coal and producing smoke and ash describe how coal is used and its effects, not why it is nonrenewable.
