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






2. 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.






3. The third purest form of coal.






4. A succession of organisms in an ecological community that constitutes a continuation of food energy from one organism to another as each consumes a lower member and - in turn - is preyed upon by a higher member.






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






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






7. A soil horizon; B receives the minerals and organic materials that are leached out of the A horizon.






8. Energy at rest - or stored energy.






9. 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.






10. Can consist of hazardous waste - industrial solid waste - or municipal waste. Many types of solid waste provide a threat to human health and the environment.






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






12. The second-purest form of coal.






13. The area or environment where an organism or ecological community normally lives or occurs.






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






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






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






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






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






19. 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.






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






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






22. 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.






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






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






25. A plate boundary at which plates are moving away from each other. This causes an upwelling of magma from the mantle to cool and form new crust.






26. An erosion-resistant marine ridge or mound consisting chiefly of compacted coral together with algal material and biochemically deposited magnesium and calcium carbonates.






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






28. 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).






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






30. In tectonic plates - the site at which an oceanic plate is sliding under a continental plate.






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






32. 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.






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






34. The biological treatment of wastewater in order to continue to remove biodegradable waste.






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






36. The number of children a couple must have in order to replace themselves in a population.






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






38. When one species feeds on another.






39. The day-to-day variations in temperature - air pressure - wind - humidity - and precipitation mediated by the atmosphere in a given region.






40. A soil horizon - horizon C is made up of larger pieces of rock that have not undergone much weathering.






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






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






43. Being extinct or the process of becoming extinct.






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






45. To convert or change into a vapor.






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






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






48. 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






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






50. A soil horizon; the layer below the O layer is called the A layer. The A layer is formed of weathered rock - with some organic material; often referred to as topsoil.
