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. An organism that cannot synthesize its own food and is dependent on complex organic substances for nutrition.






2. The molten core of the Earth.






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






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






5. The place where two plates abut each other.






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






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






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. A species whose very presence contributes to an ecosystem's diversity and whose extinction would consequently lead to the extinction of other forms of life.






10. The movement of individuals into a population.






11. The management of forest plantations for the purpose of harvesting timber.






12. 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.






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






14. In fishing - the use of long lines that have baited hooks and will be taken by numerous aquatic organisms.






15. Non-moving sources of pollution - such as factories.






16. A model that's used to predict population trends based on the birth and death rates as well as economic status of a population.






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






18. 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.






19. The practice of alternating the crops grown on a piece of land - for example - corn one year - legumes for two years - and then back to corn.






20. Pertaining to factors or things that are separate and independent from living things; nonliving.






21. The third purest form of coal.






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






23. The capacity to do work.






24. 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.






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






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






27. The random fluctuations in the frequency of the appearance of a gene in a small isolated population - presumably owing to chance - rather than natural selection.






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






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






30. The management or regulation of a resource so that its use does not exceed the capacity of the resource to regenerate itself.






31. When grass is consumed by animals at a faster rate than it can regrow.






32. Organisms that consume primary consumers.






33. The outermost shell of the atmosphere - between the mesosphere and outer space - where temperatures increase steadily with altitude.






34. When water rights are given to those who have historically used the water in a certain area.






35. When an area of vegetation is cut down and burned before being planted with crops.






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






37. The use of building materials - building placement - and design to passively collect solar energy that can be used to keep a building warm or cool.






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






39. The structure obtained if we organize the amount of energy contained in producers and consumers in an ecosystem by kilocalories per square meter - from largest to smallest.






40. The movement of individuals out of a population.






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






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






43. The observed effect of the Coriolis force - especially the deflection of an object moving above the Earth - rightward in the Northern Hemisphere - and leftward in the Southern Hemisphere.






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






45. The process of fusing two nuclei.






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






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






48. 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.






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






50. Graphical representations of populations' ages.
