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






2. The finest soil - made up of particles that are less than 0.002 mm in diameter.






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






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






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






6. In a sewage treatment plant - the initial filtration that is done to remove debris such as stones - sticks - rags - toys - and other objects that were flushed down the toilet.






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






8. Also known as transform faults - boundaries at which plates are moving past each other - sideways.






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






10. 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






11. The part of the mantle that lies just below the lithosphere.






12. 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.






13. 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.






14. 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.






15. 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.






16. A group of modern windmills.






17. When one species feeds on another.






18. The number of children an average woman will bear during her lifetime; this information is based on an analysis of data from preceding years in the population in question.






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






20. 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.






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






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






23. The observed effect of the Coriolis force - especially the deflection of an object moving above the Earth - rightward in the Northern Hemisphere - and leftward in the Southern Hemisphere.






24. The amount of the Earth's surface that's necessary to supply the needs of - and dispose of the waste from a particular population.






25. The gradual breakdown of rock into smaller and smaller particles - caused by natural chemical - physical - and biological factors.






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






27. The process in which soil bacteria convert ammonium (NH4+) to a form that can be used by plants; nitrate - or NO3.






28. Power generated using water.






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






30. The value of natural resources.






31. Organisms that are capable of interbreeding with one another and incapable of breeding with other species.






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






33. 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.






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






35. The low-rainfall region that exists on the leeward (downwind) side of a mountain range. This rain shadow is the result of the mountain range's causing precipitation on the windward side.






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






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






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






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






40. The removal of select trees in an area; this leaves the majority of the habitat in place and has less of an impact on the ecosystem.






41. Smog resulting from emissions from industry and other sources of gases produced by the burning of fossil fuels - especially coal.






42. 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.






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






44. The region draining into river system or other body of water.






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






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






47. Air currents caused by the vertical movement of air due to atmospheric heating and cooling.






48. When a species occupies a smaller niche than it would in the absence of competition.






49. A complex of interrelated food chains in an ecological community.






50. The accumulation of a substance - such as a toxic chemical - in various tissues of a living organism.
