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






2. The second-purest form of coal.






3. 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.






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






5. The movement of individuals out of a population.






6. The least pure coal.






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






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






9. Ozone that exists in the trophosphere.






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






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






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






13. Land that's fit to be cultivated.






14. 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.






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






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






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






18. A species whose very presence contributes to an ecosystem's diversity and whose extinction would consequently lead to the extinction of other forms of life.






19. An animal that only consumes other animals.






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






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






22. The third purest form of coal.






23. Close - prolonged associations between two or more different organisms of different species that may - but do not necessarily benefit the members.






24. 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.






25. A hydrocarbon deposit - such as petroleum - coal - or natural gas - derived from living matter of a previous geologic time and used for fuel.






26. 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.






27. The development and introduction of new varieties of (mainly) wheat and rice that has increased yields per acre dramatically in countries since the 1960s.






28. The solids that remain after the secondary treatment of sewage.






29. Countries that have a renewable annual water supply of less than 1 -000 m3 per person.






30. Radioactive wastes that produce high levels of ionizing radiation.






31. A cyclonic storm having winds ranging from approximately 48 to 121 km (30 to 75 miles) per hour.






32. In tectonic plates - the site at which an oceanic plate is sliding under a continental plate.






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






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






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






36. A layer of soil.






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






38. The form petroleum takes when in the ground.






39. The movement of individuals into a population.






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






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






42. When the signs and symptoms of an illness can be attributed to a specific infectious organism that resides in the building.






43. A stable - mature community in a successive series that has reached equilibrium after having evolved through stages and adapted to its environment.






44. The molten core of the Earth.






45. The day-to-day variations in temperature - air pressure - wind - humidity - and precipitation mediated by the atmosphere in a given region.






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






47. Sunlight.






48. The dosage level of a toxin at which a negative effect occurs.






49. The uppermost horizon of soil. It is primarily made up of organic material - including waste from organisms - the bodies of decomposing organisms - and live organisms.






50. 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.
