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 system of vertical and horizontal air circulation predominating in tropical and subtropical regions and creating major weather patterns.






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






3. Bacteria or fungi that absorb nutrients from nonliving organic matter like plant material - the wastes of living organisms - and corpses. They convert these materials into inorganic forms.






4. Ozone that exists in the trophosphere.






5. Species that originate and live - or occur naturally - in an area or environment.






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






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






8. The atmospheric pressure conditions corresponding to the periodic warming of El Nino and cooling of La Nina.






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






10. Energy at rest - or stored energy.






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






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






13. The solids that remain after the secondary treatment of sewage.






14. 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.






15. The place where two plates abut each other.






16. The coarsest soil - with particles 0.05 -2.0 mm in diameter.






17. A program funded by the federal government and a trust that's funded by taxes on chemicals; identifies pollutants and cleans up hazardous waste sites.






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






19. A lowland area - such as a marsh or swamp - that is saturated with moisture - especially when regarded as the natural habitat of wildlife.






20. The molten core of the Earth.






21. A process that allows the organic material in solid waste to be decomposed and reintroduced into the soil - often as fertilizer.






22. An introduced - normative species.






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






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






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






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






27. The carrier organism through which pathogens can attack.






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






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






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






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






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






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






34. Organisms in the first stages of succession.






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






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






37. A tank filled with aerobic bacteria that's used to treat sewage.






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






39. A bloom of dinoflagellates that causes reddish discoloration of coastal ocean waters. Certain dinoflagellates of the genus Gonyamfox produce toxins that kill fish and contaminate shellfish.






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






41. The form petroleum takes when in the ground.






42. The process in which soil becomes saltier and saltier until - finally - the salt prevents the growth of plants. Salinization is caused by irrigation because salts brought in with the water remain in the soil as water evaporates.






43. 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.






44. The gradual breakdown of rock into smaller and smaller particles - caused by natural chemical - physical - and biological factors.






45. When soil becomes water-logged and then dries out - and salt forms a layer on its surface.






46. The development and introduction of new varieties of (mainly) wheat and rice that has increased yields per acre dramatically in countries since the 1960s.






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






48. A specific location from which pollution is released; an example of a point source location is a factory where wood is being burned.






49. A complex of interrelated food chains in an ecological community.






50. 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.
