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.

3. To convert or change into a vapor.






4. Living or derived from living things.






5. The result of graphing a dose-response analysis.






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






7. 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






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






9. Pertaining to factors or things that are separate and independent from living things; nonliving.






10. Piles of gangue - which is the waste material that results from mining.






11. Using strategies to reduce the amount of risk (the degree of likelihood that a person will become ill upon exposure to a toxin or pathogen).






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






13. Biotic and abiotic natural ecosystems.






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






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






16. The movement of individuals into a population.






17. Gave the EPA power to set emission standards for major sources of noise - including transportation - machinery - and construction.

20. A hydrocarbon that forms as sediments are buried and pressurized.






21. 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.






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






23. The energy of motion.






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






25. 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






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






27. The value of natural resources.






28. Organisms that are capable of interbreeding with one another and incapable of breeding with other species.






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






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






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






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






33. The process of burning.






34. Organisms that reproduce early in life and often and have a high capacity for reproductive growth.






35. 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






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






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






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






39. A layer of soil.






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






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






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






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






44. When physically treated sewage water is passed into a settling tank - where suspended solids settle out as sludge; chemically treated polymers may be added to help the suspended solids separate and settle out.






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






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






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






48. The dark - crumbly - nutrient-rich material that results from the decomposition of organic material.






49. The amount of the Earth's surface that's necessary to supply the needs of - and dispose of the waste from a particular population.






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