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

2. The molten core of the Earth.

3. To convert or change into a vapor.

4. A group of modern windmills.

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

6. The process of burning.

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

8. The process of soil particles being carried away by wind or water. Erosion moves the smaller particles first and hence degrades the soil to a coarser - sandier - stonier texture.

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

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

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

12. A symbiotic relationship in which both species benefit.

13. Says that the entropy (disorder) of the universe is increasing. One corollary of the Second Law of thermodynamics is the concept that - in most energy transformations - a significant fraction of energy is lost to the universe as heat.

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

15. A nuclear reaction in which an atomic nucleus - especially a heavy nucleus such as an isotope of uranium - splits into fragments - usually two fragments of comparable mass - releasing from 100 million to several hundred million electron volts of ener

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

17. A cooling of the ocean surface off the western coast of South America - occurring periodically every 4 to 12 years and affecting Pacific and other weather patterns.

18. The random fluctuations in the frequency of the appearance of a gene in a small isolated population - presumably owing to chance - rather than natural selection.

19. The least pure coal.

20. 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

21. Power generated using water.

22. A semiconductor device that converts the energy of sunlight into electric energy.

23. The value of natural resources.

24. Creating flat platforms in the hillside that provide a level planting surface - which reduces soil runoff from the slope.

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

26. Open or forested areas built at the outer edge of a city.

27. 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.

28. Any substance than is inhaled - ingested - or absorbed at dosages sufficient to damage a living organism.

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

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

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

32. The use of building materials - building placement - and design to passively collect solar energy that can be used to keep a building warm or cool.

33. Ozone that exists in the trophosphere.

34. The unit used to describe the volume of fossil fuels.

35. A tank filled with aerobic bacteria that's used to treat sewage.

36. When trees and crops are planted together - creating a mutualistic symbiotic relationship between them.

37. The observed effect of the Coriolis force - especially the deflection of an object moving above the Earth - rightward in the Northern Hemisphere - and leftward in the Southern Hemisphere.

38. The low-rainfall region that exists on the leeward (downwind) side of a mountain range. This rain shadow is the result of the mountain range's causing precipitation on the windward side.

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

40. Organisms that consume both producers and primary consumers.

41. A severe tropical cyclone originating in the equatorial regions of the Atlantic Ocean or Caribbean Sea or eastern regions of the Pacific Ocean - traveling north - northwest - or northeast from its point of origin - and usually involving heavy rains.

42. Pollutants that are released directly into the lower atmosphere.

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

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

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

46. When an area of vegetation is cut down and burned before being planted with crops.

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

48. Organisms that derive energy from consuming nonliving organic matter.

49. A soil horizon - horizon C is made up of larger pieces of rock that have not undergone much weathering.

50. A bloom of dinoflagellates that causes reddish discoloration of coastal ocean waters. Certain dinoflagellates of the genus Gonyamfox produce toxins that kill fish and contaminate shellfish.
