Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Radioactive wastes that produce low levels of ionizing radiation.






2. When materials - such as plastic or aluminum - are used to rebuild the same product. An example of this is the use of the aluminum from aluminum cans to produce more aluminum cans.






3. A symbiotic relationship in which both species benefit.






4. Devices containing alkaline substances that precipitate out much of the sulfur dioxide from industrial plants.






5. One that has never been cut; these forests have not been seriously disturbed for several hundred years.






6. The number of children a couple must have in order to replace themselves in a population.






7. A hydrocarbon deposit - such as petroleum - coal - or natural gas - derived from living matter of a previous geologic time and used for fuel.






8. Countries that have a renewable annual water supply of about 1 -000 -2 -000 m3 per person.






9. Any water that has been used by humans. This includes human sewage - water drained from showers - tubs - sinks - dishwashers - washing machines - water from industrial processes - and storm water runoff.






10. The third purest form of coal.






11. The gradual breakdown of rock into smaller and smaller particles - caused by natural chemical - physical - and biological factors.






12. The layer of the Earth between the crust and the core.






13. A cooling of the ocean surface off the western coast of South America - occurring periodically every 4 to 12 years and affecting Pacific and other weather patterns.






14. The process of fusing two nuclei.






15. An influential theory that concerns the long-term rate of conventional oil (and other fossil fuel) extraction and depletion. It predicts that future world oil production will soon reach a peak and then rapidly decline.






16. The result of vibrations (often due to plate movements) deep in the Earth that release energy. They often occur as two plates slide past one another at a transform boundary.






17. A platinum - coated device that oxidizes most of the VOCs and some of the CO that would otherwise be emitted in exhaust - converting them to CO2.






18. Using strategies to reduce the amount of risk (the degree of likelihood that a person will become ill upon exposure to a toxin or pathogen).






19. The right - as to fishing or to the use of a riverbed - of one who owns riparian land (the land adjacent to a river or stream).






20. The value of natural resources.






21. Being extinct or the process of becoming extinct.






22. When the signs and symptoms of an illness can be attributed to a specific infectious organism that resides in the building.






23. Sunlight.






24. The process in which soil bacteria convert ammonium (NH4+) to a form that can be used by plants; nitrate - or NO3.






25. When each family in a community grows crops for themselves and rely on animal and human labor to plant and harvest crops.






26. Organisms that derive energy from consuming nonliving organic matter.






27. A cyclonic storm having winds ranging from approximately 48 to 121 km (30 to 75 miles) per hour.






28. A usually triangular alluvial deposit at the mouth of a river.






29. A fishing technique in which the ocean floor is literally scraped by heavy nets that smash everything in their path.






30. The atmospheric pressure conditions corresponding to the periodic warming of El Nino and cooling of La Nina.






31. The process of burning.






32. When a species occupies a smaller niche than it would in the absence of competition.






33. The part of the mantle that lies just below the lithosphere.






34. A specific location from which pollution is released; an example of a point source location is a factory where wood is being burned.






35. A stable - mature community in a successive series that has reached equilibrium after having evolved through stages and adapted to its environment.






36. The result of chemical interaction with the bedrock that is typical of the action of both water and atmospheric gases.






37. The process in which soil becomes saltier and saltier until - finally - the salt prevents the growth of plants. Salinization is caused by irrigation because salts brought in with the water remain in the soil as water evaporates.






38. The gaseous mass or envelope surrounding a celestial body - especially the one surrounding the Earth - which is retained by the celestial body's gravitational field.






39. Land that's fit to be cultivated.






40. The solids that remain after the secondary treatment of sewage.






41. Formed from populations of different species occupying the same geographic area.






42. Countries that have a renewable annual water supply of less than 1 -000 m3 per person.






43. Fires that typically burn only the forest's underbrush and do little damage to mature trees. Surface fires actually serve to protect the forest from more harmful fires by removing underbrush and dead materials that would burn quickly and at high temp






44. The thinning of the ozone layer over Antarctica (and to some extent - over the Arctic).






45. Pollution that does not have a specific point of release - open -loop recycling -when materials are reused to form new products.






46. This category includes organisms that consume producers (plants and algae).






47. A layer in a large body of water - such as a lake - that sharply separates regions differing in temperature - so that the temperature gradient across the layer is abrupt.






48. Organisms that consume primary consumers.






49. The dark - crumbly - nutrient-rich material that results from the decomposition of organic material.






50. Close - prolonged associations between two or more different organisms of different species that may - but do not necessarily benefit the members.
