| Petroleum (oil) | A flammable, yellow-to-black liquid composed of hydrocarbons occurring naturally beneath Earth’s surface; a nonrenewable fossil fuel processed to make gasoline used in vehicles. |
| Greenhouse Gases | the atmosphere traps heat energy close to the earth; gases like carbon dioxide and methane are added to the atmospher by humans and increase this effect. |
| Conservation | Efforts to wisely use, distribute, and protect valuable resources such as fresh water, soil, unique environments, and energy resources, as well as natural and human-made materials. |
