| what can the fossil fuel oil be used to make | plastics and gasoline |
| what can the fossil fuel natural gas be used for | it heat homes and fuel stoves |
| what is the fossil fuel coal used for | it fuels power plants and supplies electricity to homes, schools and factories |
| what is the mineral bauxite used to make | aluminum |
| what is made with aluminum | cans or foil |
| why is bauxite a nonrenewable resource and what does it mean | only a limited amount exist so there is a limit to how much aluminum can be made |
