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






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






3. 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.






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






5. Being extinct or the process of becoming extinct.






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






7. A high-speed - meandering wind current - generally moving from a westerly direction at speeds often exceeding 400 km (250 miles) per hour at altitudes of 15 to 25 km (10 to 15 miles).






8. The raising of fish and other aquatic species in captivity for harvest.






9. The part of the mantle that lies just below the lithosphere.






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






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






12. The coarsest soil - with particles 0.05 -2.0 mm in diameter.






13. When the energy released from waste incineration is used to generate electricity.






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






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






16. The A layer of soil is often referred to as topsoil and is most important for plant growth.






17. When one species feeds on another.






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






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






20. Urban areas that heat up more quickly and retain heat more than do nonurban areas.






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






22. The part of the Earth and its atmosphere in which living organisms exist or that is capable of supporting life.






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






24. A group of modern windmills.






25. To convert or change into a vapor.






26. 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.






27. 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.






28. The use of devices - such as solar panels - to collect - focus - transport - or store solar energy.






29. An area in which a particular mineral is concentrated - mining -the excavation of the Earth for the purpose of extracting ore or minerals.






30. The second-purest form of coal.






31. States that matter can neither be created nor destroyed.






32. A region of the ocean near the equator - characterized by calms - light winds - or squalls.






33. 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.






34. The point at which 50 percent of the test organisms show a negative effect from a toxin.






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






36. Bacteria - virus - or other microorganisms that can cause disease.






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






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






39. Power generated using water.






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






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






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






43. A usually triangular alluvial deposit at the mouth of a river.






44. A basic substance; chemically - a substance that absorbs hydrogen ions or releases hydroxyl ions; in reference to natural water - a measure of the base content of the water.






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






46. 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.






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






48. The number of children an average woman will bear during her lifetime; this information is based on an analysis of data from preceding years in the population in question.






49. The broad category under which selective cutting and shelter-wood cutting fall; selective deforestation.






50. A method of supplying irrigation water through tubes that literally drip water onto the soil at the base of each plant.
