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 molten core of the Earth.






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






3. Any compound that releases hydrogen ions when dissolved in water. Also - a water solution that contains a surplus of hydrogen ions.






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






5. Says that energy can neither be created nor destroyed; it can only be transferred and transformed.






6. When photochemical smog - NOx compounds - VOCs - and ozone combine to form smog with a brownish hue.






7. Change in the genetic composition of a population during successive generations as a result of natural selection acting on the genetic variation among individuals and resulting in the development of new species.






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






9. Organisms that reproduce later in life - produce fewer offspring - and devote significant time and energy to the nurturing of their offspring.






10. Calculating risk - or the degree of likelihood that a person will become ill upon exposure to a toxin or pathogen.






11. Any noise that causes stress or has the potential to damage human health.






12. The liquid that percolates to the bottom of a landfill.






13. A symbiotic relationship in which both species benefit.






14. 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.






15. States that matter can neither be created nor destroyed.






16. The process by which - according to Darwin's theory of evolution - only the organisms best adapted to their environment tend to survive and transmit their genetic characteristics in increasing numbers to succeeding generations - while those less adap






17. A group of modern windmills.






18. The industry or occupation devoted to the catching - processing - or selling of fish - shellfish - or other aquatic animals.






19. A high-speed - meandering wind current - generally moving from a westerly direction at speeds often exceeding 400 km (250 miles) per hour at altitudes of 15 to 25 km (10 to 15 miles).






20. The result of a pathogen invading a body.






21. Land that's fit to be cultivated.






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






23. An animal that only consumes other animals.






24. 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.






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






26. The dosage level of a toxin at which a negative effect occurs.






27. The more or less constant winds blowing in horizontal directions over the Earth's surface - as part of Hadley cells.






28. Resources that are often formed by very slow geologic processes - so we consider them incapable of being regenerated within the realm of human existence.






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






30. 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.






31. Species that originate and live - or occur naturally - in an area or environment.






32. 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






33. To convert or change into a vapor.






34. Any other species of fish - mammals - or birds that are caught that are not the target organism.






35. When the majority of a building's occupants experience certain symptoms that vary with the amount of time spent in the building.






36. A plate boundary where two plates are moving toward each other.






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






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






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






40. The amount of energy that plants pass on to the community of herbivores in an ecosystem.






41. An area in which a particular mineral is concentrated - mining -the excavation of the Earth for the purpose of extracting ore or minerals.






42. The vertical movement of a mass of matter due to heating and cooling; this can happen in both the atmosphere and Earth's mantle.






43. The process in which plants absorb ammonium (NH3) - ammonia ions (NH4+) - and nitrate ions (NO3) through their roots.






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






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






46. The result of graphing a dose-response analysis.






47. The region draining into river system or other body of water.






48. Any waste that poses a danger to human health; it must be dealt with in a different way from other types of waste.






49. Organisms that consume both producers and primary consumers.






50. When populations are well below the size dictated by the carrying capacity of the region they live in - they will grow exponentially - but as they approach the carrying capacity - their growth rate will decrease and the size of the population will ev
