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 number of children an average woman will bear during her lifetime; this information is based on an analysis of data from preceding years in the population in question.






2. A layer of soil.






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






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






5. The amount of time it takes for half of a radioactive sample to disappear.






6. The second-purest form of coal.






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






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






9. An organism that must obtain food energy from secondary sources - for example - by eating plant or animal matter.






10. Any substance than is inhaled - ingested - or absorbed at dosages sufficient to damage a living organism.






11. The degree to which a substance is biologically harmful.






12. 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.






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






14. Nets that are dragged through the water and indiscriminately catch everything in their path.






15. A waste product produced by the burning of coal.






16. An estimate of the amount of fossil fuel that can be obtained from reserve.






17. Bacteria - virus - or other microorganisms that can cause disease.






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






19. Living or derived from living things.






20. The process of soil particles being carried away by wind or water. Erosion moves the smaller particles first and hence degrades the soil to a coarser - sandier - stonier texture.






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






22. The process of fusing two nuclei.






23. The coarsest soil - with particles 0.05 -2.0 mm in diameter.






24. Open or forested areas built at the outer edge of a city.






25. Ozone that exists in the trophosphere.






26. The cultivation of a single crop on a farm or in a region or country; a single - homogeneous culture without diversity or dissension.






27. A process that allows the organic material in solid waste to be decomposed and reintroduced into the soil - often as fertilizer.






28. 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.






29. The amount of sugar that the plants produce in photosynthesis and subtracting from it the amount of energy the plants need for growth maintenance - repair - and reproduction.






30. Acid rain - acid hail - acid snow; all of which occur as a result of pollution in the atmosphere.






31. Air currents caused by the vertical movement of air due to atmospheric heating and cooling.






32. Organisms in the first stages of succession.






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






34. The process of burning.






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






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






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






38. 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.






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






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






41. Refers to resources - such as plants and animals - which can be regenerated if harvested at sustainable yields.






42. When physically treated sewage water is passed into a settling tank - where suspended solids settle out as sludge; chemically treated polymers may be added to help the suspended solids separate and settle out.






43. An animal that only consumes other animals.






44. Also known as plantations - these are planted and managed tracts of trees of the same age that are harvested for commercial use.






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






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






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






48. The part of the Earth and its atmosphere in which living organisms exist or that is capable of supporting life.






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






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