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






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






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






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






5. Organisms in the first stages of succession.






6. Transition in species composition of a biological community - often following ecological disturbance of the community; the establishment of a biological community in any area virtually barren of life.






7. The practice of alternating the crops grown on a piece of land - for example - corn one year - legumes for two years - and then back to corn.






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






9. Also known as transform faults - boundaries at which plates are moving past each other - sideways.






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






11. The management of forest plantations for the purpose of harvesting timber.






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






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






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






15. The liquid that percolates to the bottom of a landfill.






16. 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).






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






18. Land that's fit to be cultivated.






19. Graphical representations of populations' ages.






20. An organism such as a bacterium or protozoan - that obtains its nourishment through the oxidation of inorganic chemical compounds - as opposed to photosynthesis.






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






22. The biological treatment of wastewater in order to continue to remove biodegradable waste.






23. Any other species of fish - mammals - or birds that are caught that are not the target organism.






24. When grass is consumed by animals at a faster rate than it can regrow.






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






26. Bacteria or fungi that absorb nutrients from nonliving organic matter like plant material - the wastes of living organisms - and corpses. They convert these materials into inorganic forms.






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






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






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






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






31. Fish farming in which fish are caught in the wild and not raised in captivity for consumption.






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






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






34. The value of natural resources.






35. 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.






36. The right - as to fishing or to the use of a riverbed - of one who owns riparian land (the land adjacent to a river or stream).






37. The condition in which - at ecosystem boundaries - there is greater species diversity and biological density than there is in the heart of ecological communities.






38. 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.






39. A group of organisms of the same species that live in the same area.






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






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






42. The form petroleum takes when in the ground.






43. Organisms that consume primary consumers.






44. The management or regulation of a resource so that its use does not exceed the capacity of the resource to regenerate itself.






45. Biotic and abiotic natural ecosystems.






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






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






48. Change in the genetic composition of a population during successive generations as a result of natural selection acting on the genetic variation among individuals and resulting in the development of new species.






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






50. Energy at rest - or stored energy.
