APES Oil Water
Review Oil and Water topics
Question | Answer |
---|---|
Aquifers | Underground caverns and porous, layers of sand, gravel, or bedrock through which groundwater flows. |
Natural recharge | a process in which renewable aquifers are replenished naturally by precipitation that percolates downward through soil and rock. |
Surface water | the freshwater that flows across the earth’s land surface and into rivers, streams, lakes, reservoirs, ponds, wetlands, and estuaries. |
Surface runoff | precipitation that does not return to the atmosphere by evaporation or infiltrate into the ground. |
Watershed | The land from which surface water drains into a river, lake, wetland, or other body of water. |
Drainage basin | Synonym of watershed |
Hydrologic connection | This exists because water and groundwater eventually flow into rivers, lakes, estuaries, and wetlands. |
Reliable runoff | the amount of surface runoff that we can generally count on as a stable source of freshwater from year to year. |
Water hot spots | in these 17 western states the fierce competition for scarce water to support growing urban areas, irrigation, recreation, and wildlife could trigger intense political and legal conflicts between states and between farmers and cities during the next 20 ye |
Groundwater overpumping | Pumping the earth of water until it reaches extremely small amounts for reserve |
Land subsidence | The sinking action of land. Makes recharging impossible |
Sink Holes | Formed when the roof of an underground cavern collapses after being drained of the groundwater that supports it and creates a large surface crater. Can appear suddenly and unexpectedly. |
Dam | a barrier constructed to contain the flow of water or to keep out the sea |
Reservoir | lake used to store water for community use |
Aqueduct | a conduit that resembles a bridge but carries water over a valley |
California Water Project | One of the world’s largest water transfer projects. Uses a maze of giant dams, pumps, and aqueducts to transport water from water-rich in Northern California to southern California’s heavily populated, arid and semiarid agricultural regions and cities. |
Desalination (desalting) | Involves removing dissolved salts from ocean water or from brackish (slightly salty) water in aquifers or lakes for domestic use. Use to increase supplies of freshwater. |
Distillation | heating saltwater until it evaporates, leaves behind salts in solid form, and condenses freshwater. |
Reverse osmosis | uses high pressure to force saltwater through a membrane filter with pores small enough to remove salt. |
Microfiltration | Synonym of “reverse osmosis”. |
Drip irrigation | Above or below ground pipes or tubes that deliver water to individual plant roots. |
Microirrigation system | |
Soil moisture detectors | a small portable meter that indicates soil moisture, enabling farmers to cut their irrigation water use by 33-66% in many cases. |
Bitumen | Gooey, black, high-sulfur, heavy oil extracted from tar sand and then upgraded to synthetic fuel oil. See tar sand. |
Breeder nuclear fission reactor | Nuclear fission reactor that produces more nuclear fuel than it consumes by converting nonfissionable uranium-238 into fissionable plutonium-239 |
coal | Solid, combustible mixture of organic compounds, mixed with various amounts of water and small amounts of sulfur and nitrogen compounds. It forms in several stages as the remains of plants are subjected to heat and pressure over millions of years. |
coal gasification | Conversion of solid coal to synthetic natural gas (SNG). |
coal liquefaction | Conversion of solid coal to a liquid hydrocarbon fuel such as synthetic gasoline or methanol. |
crude oil | Gooey liquid consisting mostly of hydrocarbon compounds and small amounts of compounds containing oxygen, sulfur, and nitrogen. Extracted from underground accumulations, it is sent to oil refineries, where it is converted to heating oil, diesel fuel, gaso |
fissionable isotope | Isotope that can split apart when hit by a neutron at the right speed and thus undergo nuclear fission. Examples are uranium-235 and plutonium-239 |
kerogen | Solid, waxy mixture of hydrocarbons found in oil shale rock. Heating the rock to high temperatures causes the kerogen to vaporize. The vapor is condensed, purified, and then sent to a refinery to produce gasoline, heating oil, and other products. See also |
kilowatt | Unit of electrical power equal to 1,000 watts |
liquefied natural gas (LNG) | Natural gas converted to liquid form by cooling to a very low temperature |
liquefied petroleum gas (LPG) | Mixture of liquefied propane (C3H8) and butane (C4H10) gas removed from natural gas and used as a fuel. |
meltdown | The melting of the core of a nuclear reactor |
natural gas | Underground deposits of gases consisting of 50-90% by weight methane gas (CH4) and small amounts of heavier gaseous hydrocarbon compounds such as propane (C3H8) and butane (C4H10) |
net energy | Total amount of useful energy available from an energy resource or energy system over its lifetime, minus the amount of energy used (the first energy law), automatically wasted (the second energy law), and unnecessarily wasted in finding, processing, conc |
nuclear energy | Energy released when atomic nuclei undergo a nuclear reaction such as the spontaneous emission of radioactivity, nuclear fission, or nuclear fusion |
nuclear fission | Nuclear change in which the nuclei of certain isotopes with large mass numbers (such as uranium-235 and plutonium-239) are split apart into lighter nuclei when struck by a neutron. This process releases more neutrons and a large amount of energy. Compare |
nuclear fusion | Nuclear change in which two nuclei of isotopes of elements with a low mass number (such as hydrogen-2 and hydrogen-3) are forced together at extremely high temperatures until they fuse to form a heavier nucleus (such as helium-4). This process releases a |
Petroleum | Also known as Crude Oil, gooey liquid consisting mostly of hydrocarbon compounds and small amounts of compounds containing oxygen, sulfur, and nitrogen. In oil refineries it is converted ti heating oil, diesel fuel, gasoline, tar, and other material. |
oil sand | Deposit of a mixture of clay, sand, water, and varying amounts of a tarlike heavy oil known as bitumen. Bitumen can be extracted from tar sand by heating. It is then purified and upgraded to synthetic crude oil. See bitumen |
oil shale | Fine-grained rock containing various amounts of kerogen, a solid, waxy mixture of hydrocarbon compounds. Heating the rock to high temperatures converts the kerogen into a vapor that can be condensed to form a slow-flowing heavy oil called shale oil. See k |
petrochemicals | Chemicals obtained by refining (distilling) crude oil. They are used as raw materials in manufacturing most industrial chemicals, fertilizers, pesticides, plastics, synthetic fibers, paints, medicines, and many other products |
radioactive waste | Waste products of nuclear power plants, research, medicine, weapon production, or other processes involving nuclear reactions. See radioactivity |
shale oil | Slow-flowing, dark brown, heavy oil obtained when kerogen in oil shale is vaporized at high temperatures and then condensed. Shale oil can be refined to yield gasoline, heating oil, and other petroleum products. See kerogen, oil shale |
