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






2. The result of vibrations (often due to plate movements) deep in the Earth that release energy. They often occur as two plates slide past one another at a transform boundary.






3. A soil horizon; B receives the minerals and organic materials that are leached out of the A horizon.






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






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






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






7. The process by which the concentration of toxic substances increases in each successive link in the food chain.






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






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






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






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






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






13. Pollutants that are formed by the combination of primary pollutants in the atmosphere.






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






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






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






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






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






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






20. A platinum - coated device that oxidizes most of the VOCs and some of the CO that would otherwise be emitted in exhaust - converting them to CO2.






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






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






23. 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.






24. When companies are allowed to buy permits that allow them a certain amount of discharge of substances into certain environmental outlets. If they can reduce their amount of discharge - they are allowed to sell the remaining portion of their permit to






25. The part of the Earth and its atmosphere in which living organisms exist or that is capable of supporting life.






26. The least pure coal.






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






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






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






30. The A layer of soil is often referred to as topsoil and is most important for plant growth.






31. The process in which plants absorb ammonium (NH3) - ammonia ions (NH4+) - and nitrate ions (NO3) through their roots.






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






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






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






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






36. 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.






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






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






39. The process in which soil bacteria convert ammonium (NH4+) to a form that can be used by plants; nitrate - or NO3.






40. 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.






41. Organisms in the first stages of succession.






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






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






44. When photochemical smog - NOx compounds - VOCs - and ozone combine to form smog with a brownish hue.






45. The energy of motion.






46. The finest soil - made up of particles that are less than 0.002 mm in diameter.






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






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






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






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