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. Is equal to the number of deaths per 1 -000 members of the population in a year.






2. Land that's fit to be cultivated.






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






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






5. 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.






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






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






8. An influential theory that concerns the long-term rate of conventional oil (and other fossil fuel) extraction and depletion. It predicts that future world oil production will soon reach a peak and then rapidly decline.






9. The maximum population size that can be supported by the available resources in a region.






10. 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






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






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






13. 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.






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






15. Pollutants that are released directly into the lower atmosphere.






16. The number of children an average woman will bear during her lifetime; this information is based on an analysis of data from preceding years in the population in question.






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






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






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






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






21. The degree to which a substance is biologically harmful.






22. The form petroleum takes when in the ground.






23. 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.






24. The day-to-day use of environmental resources as food - clothing - and housing.






25. An organism that is capable of converting radiant energy or chemical energy into carbohydrates.






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






27. 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.






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






29. When populations are well below the size dictated by the carrying capacity of the region they live in - they will grow exponentially - but as they approach the carrying capacity - their growth rate will decrease and the size of the population will ev






30. Energy at rest - or stored energy.






31. 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.






32. Any noise that causes stress or has the potential to damage human health.






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






34. One that has never been cut; these forests have not been seriously disturbed for several hundred years.






35. A layer in a large body of water - such as a lake - that sharply separates regions differing in temperature - so that the temperature gradient across the layer is abrupt.






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






37. 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).






38. An estimate of the amount of fossil fuel that can be obtained from reserve.






39. Power generated using water.






40. 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.






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






42. 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.






43. Ozone that exists in the trophosphere.






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






45. When the size of an organism's natural habitat is reduced - or when development occurs that isolates a habitat.






46. The total sum of a species' use of the biotic and abiotic resources in its environment.






47. The result of a pathogen invading a body.






48. A process in which an organism is exposed to a toxin at different concentrations - and the dosage that causes the death of the organism is recorded.






49. To convert or change into a vapor.






50. The process of burning.
