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






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






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






4. The part of the wide lower course of a river where its current is met by the tides.






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






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






7. Being extinct or the process of becoming extinct.






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






9. 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.






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






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






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






13. 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. ...






14. The least pure coal.






15. Radioactive wastes that produce low levels of ionizing radiation.






16. When water rights are given to those who have historically used the water in a certain area.






17. 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).






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






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






20. The result of vibrations (often due to plate movements) deep in the Earth that release energy. They often occur as two plates slide past one another at a transform boundary.






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






22. Close - prolonged associations between two or more different organisms of different species that may - but do not necessarily benefit the members.






23. 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.






24. A process in which cold - often nutrient-rich - waters from the ocean depths rise to the surface.






25. Piles of gangue - which is the waste material that results from mining.






26. A specific location from which pollution is released; an example of a point source location is a factory where wood is being burned.






27. Non-moving sources of pollution - such as factories.






28. Organisms in the first stages of succession.






29. Ozone that exists in the trophosphere.






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






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






32. The dark - crumbly - nutrient-rich material that results from the decomposition of organic material.






33. 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.






34. The movement of individuals into a population.






35. An organism that cannot synthesize its own food and is dependent on complex organic substances for nutrition.






36. The degree to which a substance is biologically harmful.






37. An organism that obtains organic food molecules without eating other organisms or substances derived from other organisms. autotrophs use energy from the sun or from the oxidation of inorganic substances to make organic molecules from inorganic ones.






38. 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.






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






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






41. 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.






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






43. The process of fusing two nuclei.






44. 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






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






46. The right - as to fishing or to the use of a riverbed - of one who owns riparian land (the land adjacent to a river or stream).






47. Radioactive wastes that produce high levels of ionizing radiation.






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






49. The capacity to do work.






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