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. Organisms that consume both producers and primary consumers.






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






3. The removal of trees for agricultural purposes or purposes of exportation.






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






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






6. Calculating risk - or the degree of likelihood that a person will become ill upon exposure to a toxin or pathogen.






7. The least pure coal.






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






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






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






11. The amount of energy that plants pass on to the community of herbivores in an ecosystem.






12. 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.






13. 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.






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






15. The process by which - according to Darwin's theory of evolution - only the organisms best adapted to their environment tend to survive and transmit their genetic characteristics in increasing numbers to succeeding generations - while those less adap






16. A place where a large quantity of a resource sits for a long period of time.






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






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






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






20. The part of the mantle that lies just below the lithosphere.






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






22. 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.






23. The process by which specialized bacteria (mostly anaerobic bacteria) convert ammonia to NOy NO2 - and N2 and release it back to the atmosphere.






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






25. A region of the ocean near the equator - characterized by calms - light winds - or squalls.






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






27. 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






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






29. Organisms that reproduce later in life - produce fewer offspring - and devote significant time and energy to the nurturing of their offspring.






30. 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. ...






31. The use of devices - such as solar panels - to collect - focus - transport - or store solar energy.






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






33. An underground layer of porous rock - sand - or other material that allows the movement of water between layers of nonporous rock or clay. Aquifers are frequently tapped for wells.






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






35. The vertical movement of a mass of matter due to heating and cooling; this can happen in both the atmosphere and Earth's mantle.






36. The molten core of the Earth.






37. The amount that the population would grow if there were unlimited resources in its environment.






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






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






40. Fires that typically burn only the forest's underbrush and do little damage to mature trees. Surface fires actually serve to protect the forest from more harmful fires by removing underbrush and dead materials that would burn quickly and at high temp






41. 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.






42. The more or less constant winds blowing in horizontal directions over the Earth's surface - as part of Hadley cells.






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






44. The point at which 50 percent of the test organisms die from a toxin.






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






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






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






48. 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.






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






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