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. When ecological succession begins in a virtually lifeless area - such as the area behind a moving glacier.






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






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






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






5. The water from which a river rises; a source.






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






7. 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.






8. When one species feeds on another.






9. The rocks and Earth that is removed when mining for a commercially valuable mineral resource.






10. A region of the ocean near the equator - characterized by calms - light winds - or squalls.






11. 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.






12. The edges of tectonic plates.






13. Each of the feeding levels in a food chain.






14. Creating flat platforms in the hillside that provide a level planting surface - which reduces soil runoff from the slope.






15. 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.






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






17. A process in which an organism is exposed to a toxin at different concentrations - and the dosage that causes the death of the organism is recorded.






18. 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.






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






20. The number of live births per 1 -000 members of the population in a year.






21. An effect that results from long -term exposure to low levels of toxin.






22. A method of supplying irrigation water through tubes that literally drip water onto the soil at the base of each plant.






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






24. Power generated using water.






25. 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.






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






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






28. An opening in the Earth's crust through which molten lava - ash - and gases are ejected.






29. When the size of an organism's natural habitat is reduced - or when development occurs that isolates a habitat.






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






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






32. The removal of all of the trees in an area.






33. Soil composed of a mixture of sand - clay - silt - and organic matter.






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






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






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






37. Being extinct or the process of becoming extinct.






38. An organism that is capable of converting radiant energy or chemical energy into carbohydrates.






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






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






41. The process of fusing two nuclei.






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






43. The broad category under which selective cutting and shelter-wood cutting fall; selective deforestation.






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






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






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






47. Radioactive wastes that produce high levels of ionizing radiation.






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






49. Organisms that consume both producers and primary consumers.






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