All are correct except # 10 and #14 is wrong. 10 is natural gas. Nonrenewable resources are natural gas but renewable resources are the sun, wind and all the stuff the world has cuz how ever much we use it, it never runs out but natural gas does and it take years to make more. and 14 is global warming. HELLOO! A rise is earths average temperature, posibly CAUSED BY AN INCREASE OF GREEN HOUSE GASES, is known as GLOBAL WARMING. I just got this from a book.
