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






2. The outer part of the Earth - consisting of the crust and upper mantle - approximately 100 km (62 miles) thick.






3. An effect that results from long -term exposure to low levels of toxin.






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






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






6. A layer in a large body of water - such as a lake - that sharply separates regions differing in temperature - so that the temperature gradient across the layer is abrupt.






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






8. 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).






9. Soil with particles 0.002 -0.05 mm in diameter.






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






11. 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.






12. 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.






13. Ozone that exists in the trophosphere.






14. 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.






15. A layer of soil.






16. An organism that is capable of converting radiant energy or chemical energy into carbohydrates.






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






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






19. 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.






20. Organisms that reproduce later in life - produce fewer offspring - and devote significant time and energy to the nurturing of their offspring.






21. 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.






22. The value of natural resources.






23. The biological treatment of wastewater in order to continue to remove biodegradable waste.






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






25. Is equal to the number of deaths per 1 -000 members of the population in a year.






26. Involves the sinking of shafts to reach underground deposits. In this type of mining - networks of tunnels are dug or blasted and humans enter these tunnels in order to manually retrieve the coal.






27. Any weathering that's caused by the activities of living organisms.






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






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






30. The day-to-day use of environmental resources as food - clothing - and housing.






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






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






33. 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).






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






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






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






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






38. Can consist of hazardous waste - industrial solid waste - or municipal waste. Many types of solid waste provide a threat to human health and the environment.






39. Also known as plantations - these are planted and managed tracts of trees of the same age that are harvested for commercial use.






40. 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.






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






42. The third purest form of coal.






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






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






45. An estimate of the amount of fossil fuel that can be obtained from reserve.






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






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






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






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






50. An organism such as a bacterium or protozoan - that obtains its nourishment through the oxidation of inorganic chemical compounds - as opposed to photosynthesis.
