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. Acid rain - acid hail - acid snow; all of which occur as a result of pollution in the atmosphere.






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






3. Any compound that releases hydrogen ions when dissolved in water. Also - a water solution that contains a surplus of hydrogen ions.






4. Smog resulting from emissions from industry and other sources of gases produced by the burning of fossil fuels - especially coal.






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






6. The rocks and Earth that is removed when mining for a commercially valuable mineral resource.






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






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






9. When each family in a community grows crops for themselves and rely on animal and human labor to plant and harvest crops.






10. 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.






11. Air currents caused by the vertical movement of air due to atmospheric heating and cooling.






12. The least pure coal.






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






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






15. 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.






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






17. Drilling a hole in the ground that's below the water table to hold waste.






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






19. 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.






20. 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.






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






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






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






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






25. The process of burning.






26. 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






27. The conversion of atmospheric nitrogen into compounds - such as ammonia - by natural agencies or various industrial processes.






28. The maintenance of a species or ecosystem in order to ensure their perpetuation - with no concern as to their potential monetary value






29. Poor nutrition that results from an insufficient or poorly balanced diet.






30. The amount of time it takes for half of a radioactive sample to disappear.






31. 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. ...






32. Power generated using water.






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






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






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






36. 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.






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






38. 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.






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






40. Any weathering that's caused by the activities of living organisms.






41. The broad category under which selective cutting and shelter-wood cutting fall; selective deforestation.






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






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






44. 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.






45. The process that occurs when two different species in a region compete and the better adapted species wins.






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






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






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






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






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