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 vertical movement of a mass of matter due to heating and cooling; this can happen in both the atmosphere and Earth's mantle.






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






3. The edges of tectonic plates.






4. The third purest form of coal.






5. Power generated using water.






6. Involves the removal of the Earth's surface all the way down to the level of the mineral seam.






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






8. Living or derived from living things.






9. The total sum of a species' use of the biotic and abiotic resources in its environment.






10. 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.






11. The second-purest form of coal.






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






13. A succession of organisms in an ecological community that constitutes a continuation of food energy from one organism to another as each consumes a lower member and - in turn - is preyed upon by a higher member.






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






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






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






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






18. Devices containing alkaline substances that precipitate out much of the sulfur dioxide from industrial plants.






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






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






21. A climate variation that takes place in the tropical Pacific about every three to seven years - for a duration of about one year.






22. 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.






23. The thinning of the ozone layer over Antarctica (and to some extent - over the Arctic).






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






25. When ecological succession begins in a virtually lifeless area - such as the area behind a moving glacier.






26. A process in which rows of crops are plowed across the hillside; this prevents the erosion that can occur when rows are cut up and down on a slope. ...






27. 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






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






29. Organisms in the first stages of succession.






30. 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.






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






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






33. An erosion-resistant marine ridge or mound consisting chiefly of compacted coral together with algal material and biochemically deposited magnesium and calcium carbonates.






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






35. Any water that has been used by humans. This includes human sewage - water drained from showers - tubs - sinks - dishwashers - washing machines - water from industrial processes - and storm water runoff.






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






37. When populations are well below the size dictated by the carrying capacity of the region they live in - they will grow exponentially - but as they approach the carrying capacity - their growth rate will decrease and the size of the population will ev






38. The bedrock - which lies below all of the other layers of soil - is referred to as the R horizon.






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






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






41. One that has never been cut; these forests have not been seriously disturbed for several hundred years.






42. Graphical representations of populations' ages.






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






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






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






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






47. Organisms that consume secondary consumers or other tertiary consumers.






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






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






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