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. The phenomenon whereby the Earth's atmosphere traps solar radiation - caused by the presence in the atmosphere of gases such as carbon dioxide - water vapor - and methane that allow incoming sunlight to pass through - but absorb heat radiated back fr






2. A cooling of the ocean surface off the western coast of South America - occurring periodically every 4 to 12 years and affecting Pacific and other weather patterns.






3. Countries that have a renewable annual water supply of about 1 -000 -2 -000 m3 per person.






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






5. Close - prolonged associations between two or more different organisms of different species that may - but do not necessarily benefit the members.






6. An organism that must obtain food energy from secondary sources - for example - by eating plant or animal matter.






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






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






9. The right - as to fishing or to the use of a riverbed - of one who owns riparian land (the land adjacent to a river or stream).






10. A severe tropical cyclone originating in the equatorial regions of the Atlantic Ocean or Caribbean Sea or eastern regions of the Pacific Ocean - traveling north - northwest - or northeast from its point of origin - and usually involving heavy rains.






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






12. Graphical representations of populations' ages.






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






14. 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.






15. A high-speed - meandering wind current - generally moving from a westerly direction at speeds often exceeding 400 km (250 miles) per hour at altitudes of 15 to 25 km (10 to 15 miles).






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






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






18. Ozone that exists in the trophosphere.






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






20. This category includes organisms that consume producers (plants and algae).






21. An introduced - normative species.






22. A fishing technique in which the ocean floor is literally scraped by heavy nets that smash everything in their path.






23. In a sewage treatment plant - the initial filtration that is done to remove debris such as stones - sticks - rags - toys - and other objects that were flushed down the toilet.






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






25. Areas where cutting has occurred and a new - younger forest has arisen.






26. Energy at rest - or stored energy.






27. 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.






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






29. A symbiotic relationship in which one member is helped by the association and the other is harmed.






30. Organisms that consume secondary consumers or other tertiary consumers.






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






32. Any waste that poses a danger to human health; it must be dealt with in a different way from other types of waste.






33. Urban areas that heat up more quickly and retain heat more than do nonurban areas.






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






35. A process in which rows of crops are plowed across the hillside; this prevents the erosion that can occur when rows are cut up and down on a slope. ...






36. When trees and crops are planted together - creating a mutualistic symbiotic relationship between them.






37. An intensification of the Greenhouse Effect due to the increased presence of heat-trapping gases in the atmosphere.






38. The value of natural resources.






39. The dosage level of a toxin at which a negative effect occurs.






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






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






42. To convert or change into a vapor.






43. Also known as plantations - these are planted and managed tracts of trees of the same age that are harvested for commercial use.






44. A species whose very presence contributes to an ecosystem's diversity and whose extinction would consequently lead to the extinction of other forms of life.






45. When materials - such as plastic or aluminum - are used to rebuild the same product. An example of this is the use of the aluminum from aluminum cans to produce more aluminum cans.






46. 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.






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






48. Any substance that has an LD50 - of 50 mg or less per kg of body weight.






49. 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.






50. An organism that obtains organic food molecules without eating other organisms or substances derived from other organisms. autotrophs use energy from the sun or from the oxidation of inorganic substances to make organic molecules from inorganic ones.
