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 third purest form of coal.






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






3. The removal of all of the trees in an area.






4. Graphical representations of populations' ages.






5. The area or environment where an organism or ecological community normally lives or occurs.






6. The more or less constant winds blowing in horizontal directions over the Earth's surface - as part of Hadley cells.






7. 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.






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






9. Power generated using water.






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






11. Says that energy can neither be created nor destroyed; it can only be transferred and transformed.






12. 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






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






14. The gaseous mass or envelope surrounding a celestial body - especially the one surrounding the Earth - which is retained by the celestial body's gravitational field.






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






16. Refers to when farmers plant seeds without using a plow to turn the soil.






17. A symbiotic relationship in which one member is helped by the association and the other is harmed.






18. Soil composed of a mixture of sand - clay - silt - and organic matter.






19. Is the practice of planting bands of different crops across a hillside.






20. 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.






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






22. 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.






23. The process in green plants and certain other organisms by which carbohydrates are synthesized from carbon dioxide and water using light as an energy source. Most forms of photosynthesis release oxygen as a byproduct.






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






25. A hydrocarbon deposit - such as petroleum - coal - or natural gas - derived from living matter of a previous geologic time and used for fuel.






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






27. Refers to resources - such as plants and animals - which can be regenerated if harvested at sustainable yields.






28. The act or process of transpiring - or releasing water vapor - especially through the stomata of plant tissue or the pores of the skin.






29. The amount of sugar that the plants produce in photosynthesis and subtracting from it the amount of energy the plants need for growth maintenance - repair - and reproduction.






30. Land that's fit to be cultivated.






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






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






33. A lowland area - such as a marsh or swamp - that is saturated with moisture - especially when regarded as the natural habitat of wildlife.






34. 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.






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






36. The place where two plates abut each other.






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






38. The structure obtained if we organize the amount of energy contained in producers and consumers in an ecosystem by kilocalories per square meter - from largest to smallest.






39. Biotic and abiotic natural ecosystems.






40. 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).






41. Ozone that exists in the trophosphere.






42. Areas where cutting has occurred and a new - younger forest has arisen.






43. A symbiotic relationship in which both species benefit.






44. A cyclonic storm having winds ranging from approximately 48 to 121 km (30 to 75 miles) per hour.






45. When mature trees are cut over a period of time (usually10 -20 years); this leaves mature trees - which can reseed the forest - in place.






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






47. Occurs when infection causes a change in the state of health.






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






49. A long - relatively narrow island running parallel to the mainland-built up by the action of waves and currents and serving to protect the coast from erosion by surf and tidal surges.






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