UNIT ONE – HYDROSPHERE VOCABULARY 1. 2. 3. 4. 5. 6. 7. Aquifer – layer of permeable rock or sediment with usable groundwater 21. Bio-indicators – organisms that are used to monitor the health of an environment Condensation – water changes from a gas to a liquid Density – amount of mass in a unit of volume, d=m/v Dissolved gases – in water: oxygen, carbon dioxide, nitrogen 22. Precipitation – water coming from atmosphere to earth as rain, snow, or hail 23. Reservoir –a natural or artificial lake, storage pond or impoundment from a dam 8. 9. 10. 11. 12. Evaporation – water changes from a liquid to a gas Glaciers – large, slow-moving mass of ice Ground water – water in the ground Hydrosphere – all the water on Earth (hydro=water, sphere=shape of Earth) 13. 14. Dissolved oxygen – amount of oxygen dissolved in ocean Estuary – semi-enclosed coastal body of water, sea and freshwater, filters pollutants, breeding area Hydrothermal vents – heat escaping from inside Earth, underwater, near volcanoes, supports diverse life Ice caps – ice mass that covers land area (ex. mountain peak) Nitrates – nitrogen compounds involved in eutrophication – too many nitrates leads to less oxygen which leads to fish death 15. Non-point source pollution – pollution that comes from a wide area (ex. farm fields) 16. Over fishing – fisherman catch too many fish too quickly so the fish cannot reproduce and the fish supply begins to run out pH – measure of acidity/basicity of a solution, scale from 1-14, closer to 1 – acid, closer to 14 – base, water is neutral at 7 (half way on scale) Point Source pollution– a single identifiable source of air, water, thermal, noise or light pollution Polarity – molecule has a charge that pulls other molecules towards it Pollutant run-off –don’t sink into ground, instead runs across Earth’s surface to water 17. 18. 19. 20. Potability –water safe enough to be consumed by humans or used with low risk of immediate or long term harm which is used to store water 24. 25. 26. 27. River – freshwater watercourse that flows toward a larger body of water River basin – aka drainage basin, water drains from a specific area down a river Salinity – measure of the amount of salts dissolved in seawater Sonar – Sound Navigation and Ranging, technique that uses sound to navigate (ex. dolphin, bat) 28. Stewardship – being a good citizen (ex. pick up trash, recycle, protect environment) 29. 30. 31. 32. 33. 34. 35. Stream – flowing body of water, smaller than a river Submersibles – underwater vessel Surface tension –surface water sticks together like a film Surface water – water at the Earth’s surface Turbidity – cloudiness or haziness of a liquid caused by particles 36. 37. 38. 39. Vegetative Buffer – is an undeveloped area directly adjacent to a body of water Water cycle – process of evaporation, condensation, and precipitation Water quality –the chemical, physical and biological characteristics of water Water treatment–industrial-scale processes that make water more acceptable for an end-use, which may be drinking, industrial, or medical Watershed – area of land where all of the water that is under it or drains off of it goes into the same place 40. 41. Universal solvent – water is able to dissolve many substances Upwelling – current that brings deep, cold water to the ocean surface, mixes nutrients also Well – man-made holder of water that pumps water to a house, accesses water in underground aquifer UNIT ONE – HYDROSPHERE VOCABULARY 1. 2. 3. 4. 5. 6. 7.
