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. States that matter can neither be created nor destroyed.






2. 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.






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






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






5. 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.






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






7. Devices containing alkaline substances that precipitate out much of the sulfur dioxide from industrial plants.






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






9. The movement of individuals out of a population.






10. Radioactive wastes that produce low levels of ionizing radiation.






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






12. A process in which cold - often nutrient-rich - waters from the ocean depths rise to the surface.






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






14. The cleanest-burning coal; almost pure carbon.






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






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






17. To convert or change into a vapor.






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






19. The bedrock - which lies below all of the other layers of soil - is referred to as the R horizon.






20. The process in green plants and certain other organisms by which carbohydrates are synthesized from carbon dioxide and water using light as an energy source. Most forms of photosynthesis release oxygen as a byproduct.






21. The point at which 50 percent of the test organisms die from a toxin.






22. Organisms that are capable of interbreeding with one another and incapable of breeding with other species.






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






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






25. A fiscal policy that lowers taxes on income - including wages and profit - and raises taxes on consumption - particularly the unsustainable consumption of non-renewable resources.






26. The process by which the concentration of toxic substances increases in each successive link in the food chain.






27. 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.






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






29. The accumulation of a substance - such as a toxic chemical - in various tissues of a living organism.






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






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






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






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






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






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






36. 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






37. The process of burning.






38. The place where two plates abut each other.






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






40. 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.






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






42. A group of modern windmills.






43. 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






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






45. 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.






46. 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).






47. Energy at rest - or stored energy.






48. When companies are allowed to buy permits that allow them a certain amount of discharge of substances into certain environmental outlets. If they can reduce their amount of discharge - they are allowed to sell the remaining portion of their permit to






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






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