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. The raising of fish and other aquatic species in captivity for harvest.






2. Any process that breaks rock down into smaller pieces without changing the chemistry of the rock; typically wind and water.






3. 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.






4. The movement of individuals into a population.






5. A severe tropical cyclone originating in the equatorial regions of the Atlantic Ocean or Caribbean Sea or eastern regions of the Pacific Ocean - traveling north - northwest - or northeast from its point of origin - and usually involving heavy rains.






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






7. The capacity to do work.






8. When mature trees are cut over a period of time (usually10 -20 years); this leaves mature trees - which can reseed the forest - in place.






9. An underground layer of porous rock - sand - or other material that allows the movement of water between layers of nonporous rock or clay. Aquifers are frequently tapped for wells.






10. The process that occurs when two different species in a region compete and the better adapted species wins.






11. Ozone that exists in the trophosphere.






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






13. Pollutants that are released directly into the lower atmosphere.






14. The part of the wide lower course of a river where its current is met by the tides.






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






16. An organism such as a bacterium or protozoan - that obtains its nourishment through the oxidation of inorganic chemical compounds - as opposed to photosynthesis.






17. The point at which 50 percent of the test organisms show a negative effect from a toxin.






18. An introduced - normative species.






19. A tank filled with aerobic bacteria that's used to treat sewage.






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






21. A group of organisms of the same species that live in the same area.






22. A nuclear reaction in which an atomic nucleus - especially a heavy nucleus such as an isotope of uranium - splits into fragments - usually two fragments of comparable mass - releasing from 100 million to several hundred million electron volts of ener






23. Pollutants that are formed by the combination of primary pollutants in the atmosphere.






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






25. Gave the EPA power to set emission standards for major sources of noise - including transportation - machinery - and construction.






26. In a sewage treatment plant - the initial filtration that is done to remove debris such as stones - sticks - rags - toys - and other objects that were flushed down the toilet.






27. The maximum population size that can be supported by the available resources in a region.






28. The removal of select trees in an area; this leaves the majority of the habitat in place and has less of an impact on the ecosystem.






29. The process in which animals (and plants!) breathe and give off carbon dioxide from cellular metabolism.






30. A semiconductor device that converts the energy of sunlight into electric energy.






31. Is the practice of planting bands of different crops across a hillside.






32. The fraction of solar energy that is reflected back into space.






33. The phenomenon whereby the Earth's atmosphere traps solar radiation - caused by the presence in the atmosphere of gases such as carbon dioxide - water vapor - and methane that allow incoming sunlight to pass through - but absorb heat radiated back fr






34. The amount that the population would grow if there were unlimited resources in its environment.






35. The point at which 50 percent of the test organisms die from a toxin.






36. 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.






37. 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.






38. Any substance that has an LD50 - of 50 mg or less per kg of body weight.






39. An organism that obtains organic food molecules without eating other organisms or substances derived from other organisms. autotrophs use energy from the sun or from the oxidation of inorganic substances to make organic molecules from inorganic ones.






40. Drilling a hole in the ground that's below the water table to hold waste.






41. Areas where cutting has occurred and a new - younger forest has arisen.






42. 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.






43. The day-to-day use of environmental resources as food - clothing - and housing.






44. 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).






45. The effect caused by a short exposure to a high level of toxin.






46. The cleanest-burning coal; almost pure carbon.






47. Poor nutrition that results from an insufficient or poorly balanced diet.






48. Refers to when farmers plant seeds without using a plow to turn the soil.






49. The low-rainfall region that exists on the leeward (downwind) side of a mountain range. This rain shadow is the result of the mountain range's causing precipitation on the windward side.






50. Soil with particles 0.002 -0.05 mm in diameter.
