NON RENEWABLE RESOURCES
| Term | Definition |
|---|---|
| Energy | is the ability to do work or cause a change |
| kinetic energy | the energy that an object has due to its motion |
| potential energy | is energy that an object has because of its position or shape |
| Combustion | 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 avaliable somewhere on Earth's surface , or they are replaced in a relatively short time |
| non renewable energy | cannot be replaced |
| Electricity | energy made avaliable by the flow of an electric charge |
| strip mining | 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 | a dark , liquid fossil fuel made up mostly by hydrocarbons , petroleum is found in underground deposits |
| petrochemicals | are chemical compounds thst sre derived from oil and used to make products |
| oil sands | deposits of moist sand and clay containing bituement |
| 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 conservative | 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 | the splitting of an atoms nucleus into two smaller nuclei |
| Nuclear reactor | genertaes electricity by controlled fission reactions |
| meltdowns | the fuel rods produced so much heat that they melted |
| nuclear waste | radioactive material left over from the production of energy and other processes |
| nuclear fusion | small nuclei of lightweight elementsare forced together to form a heavier nucleus |
