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. In fishing - the use of long lines that have baited hooks and will be taken by numerous aquatic organisms.






2. When physically treated sewage water is passed into a settling tank - where suspended solids settle out as sludge; chemically treated polymers may be added to help the suspended solids separate and settle out.






3. A hydrocarbon that forms as sediments are buried and pressurized.






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






5. The maintenance of a species or ecosystem in order to ensure their perpetuation - with no concern as to their potential monetary value






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






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






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






9. An influential theory that concerns the long - term rate of conventional oil (and other fossil fuel) extraction and depletion. It predicts that future world oil production will soon reach a peak and then rapidly decline.






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






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






12. A fishing technique in which the ocean floor is literally scraped by heavy nets that smash everything in their path.






13. 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.






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






15. A soil horizon; the layer below the O layer is called the A layer. The A layer is formed of weathered rock - with some organic material; often referred to as topsoil.






16. The edges of tectonic plates.






17. The solids that remain after the secondary treatment of sewage.






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






19. Pollutants that are formed by the combination of primary pollutants in the atmosphere.






20. The uppermost horizon of soil. It is primarily made up of organic material - including waste from organisms - the bodies of decomposing organisms - and live organisms.






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






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






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






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






25. Fish farming in which fish are caught in the wild and not raised in captivity for consumption.






26. The effect caused by a short exposure to a high level of toxin.






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






28. 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.






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






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






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






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






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






34. 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.






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






36. 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.






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






38. The atmospheric pressure conditions corresponding to the periodic warming of El Nino and cooling of La Nina.






39. Sunlight.






40. 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.






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






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






43. A program funded by the federal government and a trust that's funded by taxes on chemicals; identifies pollutants and cleans up hazardous waste sites.






44. Resources that are often formed by very slow geologic processes - so we consider them incapable of being regenerated within the realm of human existence.






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






46. The dosage level of a toxin at which a negative effect occurs.






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






48. The maximum population size that can be supported by the available resources in a region.






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






50. 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.
