| Term | Definition |
|---|---|
| Energy | Is the ability to do work or cause a change. |
| Kinetic energy | is the energy that an object has due to its motion. |
| Potential energy | is the energy that an object has because of its position or shape. |
| Combustion | is the process in which a fuel burns because it combines rapidly with oxygen. |
| Energy efficiency | is an expression of how much of the energy put into a system actually does useful work. |
| renewable energy | are nearly always available some where on Earth's surface or they are replaced in a relatively short time. |
| nonrenewable energy | in contrast cannot be replaced. |
| Electricity | which is energy made available by the flow of an electric charge is considered a secondary source of energy because it must be pro |
| Strip mining | is the extraction of a mineral by removing a strip of the layers of soil and rock on top of the mineral deposit. |
| Subsurface mining | is typically the practice of digging shafts deep into the ground to find and remove a mineral. |
| petroleum | is a dark liquid fossil fuel made up mostly of hydrocarbons. |
| Petrochemicals | are chemical compounds that are derived from oil and used to make products. |
| oil sands | are deposits of moist sand and clay containing bitumen. |
| Oil shale | is rock filled with a mixture of hydrocarbons. |
| Methane hydrate | is an ice like solid that consists of molecules of methane within a crystal network of water molecules. |
| Acid drainage | occurs when sulfide minerals in exposed rock surfaces react with oxygen and rainwater to produce sulfuric acid. |
| Energy conservation | is the practice of reducing energy use to meet those goals. |
| Nuclear energy | is the energy that holds these particles together in the nucleus |
| Nuclear fission | is the splitting of an atom's nucleus into two smaller nuclei |
| nuclear reactor | which generates electricity by controlled fission reactions. |
| meltdown | High amounts of radiation were released over the next several days |
| nuclear waste | which is radioactive material left over from the production of energy and other processes |
| nuclear fusion | small nuclei of lightweight elements are forced together to form a heavier nucleus. |
