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. Energy at rest - or stored energy.






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






3. A basic substance; chemically - a substance that absorbs hydrogen ions or releases hydroxyl ions; in reference to natural water - a measure of the base content of the water.






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






5. The process of fusing two nuclei.






6. 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.






7. Occurs when infection causes a change in the state of health.






8. The number of individuals of a population that inhabit a certain unit of land or water area.






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






10. The industry or occupation devoted to the catching - processing - or selling of fish - shellfish - or other aquatic animals.






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






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






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






14. 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.






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






16. The point at which 50 percent of the test organisms show a negative effect from a toxin.






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






18. 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.






19. A group of modern windmills.






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






21. Organisms that derive energy from consuming nonliving organic matter.






22. Formed from populations of different species occupying the same geographic area.






23. The act or process of transpiring - or releasing water vapor - especially through the stomata of plant tissue or the pores of the skin.






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






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






26. Says that the entropy (disorder) of the universe is increasing. One corollary of the Second Law of thermodynamics is the concept that - in most energy transformations - a significant fraction of energy is lost to the universe as heat.






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






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






29. 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.






30. The movement of individuals into a population.






31. The use of devices - such as solar panels - to collect - focus - transport - or store solar energy.






32. Any water that has been used by humans. This includes human sewage - water drained from showers - tubs - sinks - dishwashers - washing machines - water from industrial processes - and storm water runoff.






33. The second-purest form of coal.






34. A climate variation that takes place in the tropical Pacific about every three to seven years - for a duration of about one year.






35. Land that's fit to be cultivated.






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






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






38. A symbiotic relationship in which both species benefit.






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






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






41. 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.






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






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






44. A long - relatively narrow island running parallel to the mainland-built up by the action of waves and currents and serving to protect the coast from erosion by surf and tidal surges.






45. Involves the sinking of shafts to reach underground deposits. In this type of mining - networks of tunnels are dug or blasted and humans enter these tunnels in order to manually retrieve the coal.






46. Smog resulting from emissions from industry and other sources of gases produced by the burning of fossil fuels.






47. The outer part of the Earth - consisting of the crust and upper mantle - approximately 100 km (62 miles) thick.






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






49. Power generated using water.






50. 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).
