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






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






3. 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.






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






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






6. 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






7. Biotic and abiotic natural ecosystems.






8. When a species occupies a smaller niche than it would in the absence of competition.






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






10. An influential theory that concerns the long - term rate of conventional oil (and other fossil fuel) extraction and depletion. It predicts that future world oil production will soon reach a peak and then rapidly decline.






11. The rocks and Earth that is removed when mining for a commercially valuable mineral resource.






12. The process that occurs when two different species in a region compete and the better adapted species wins.






13. An organism that must obtain food energy from secondary sources - for example - by eating plant or animal matter.






14. The cultivation of a single crop on a farm or in a region or country; a single - homogeneous culture without diversity or dissension.






15. The process in which soil becomes saltier and saltier until - finally - the salt prevents the growth of plants. Salinization is caused by irrigation because salts brought in with the water remain in the soil as water evaporates.






16. 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.






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






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






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






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






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






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






23. A plate boundary at which plates are moving away from each other. This causes an upwelling of magma from the mantle to cool and form new crust.






24. An opening in the Earth's crust through which molten lava - ash - and gases are ejected.






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






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






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






28. When one species feeds on another.






29. The form petroleum takes when in the ground.






30. The process of burning.






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






32. An influential theory that concerns the long-term rate of conventional oil (and other fossil fuel) extraction and depletion. It predicts that future world oil production will soon reach a peak and then rapidly decline.






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






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






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






36. 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.






37. The energy of motion.






38. 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.






39. 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.






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






41. The layer of the Earth between the crust and the core.






42. 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.






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






44. 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.






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






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






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






48. A symbiotic relationship in which both species benefit.






49. A complex of interrelated food chains in an ecological community.






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