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. When populations are well below the size dictated by the carrying capacity of the region they live in - they will grow exponentially - but as they approach the carrying capacity - their growth rate will decrease and the size of the population will ev






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






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






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






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






6. A layer of soil.






7. The molten core of the Earth.






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






9. 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.






10. Land that's fit to be cultivated.






11. A process that allows the organic material in solid waste to be decomposed and reintroduced into the soil - often as fertilizer.






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






13. A process in which an organism is exposed to a toxin at different concentrations - and the dosage that causes the death of the organism is recorded.






14. 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.






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

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






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






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






21. When companies are allowed to buy permits that allow them a certain amount of discharge of substances into certain environmental outlets. If they can reduce their amount of discharge - they are allowed to sell the remaining portion of their permit to






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

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






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






26. Power generated using water.






27. The A layer of soil is often referred to as topsoil and is most important for plant growth.






28. 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).






29. Being extinct or the process of becoming extinct.






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






31. Nets that are dragged through the water and indiscriminately catch everything in their path.






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






33. The management or regulation of a resource so that its use does not exceed the capacity of the resource to regenerate itself.






34. Poor nutrition that results from an insufficient or poorly balanced diet.






35. The layer of the Earth between the crust and the core.






36. 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.






37. The water from which a river rises; a source.






38. The second-purest form of coal.






39. An area in which a particular mineral is concentrated - mining -the excavation of the Earth for the purpose of extracting ore or minerals.






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






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






42. The form petroleum takes when in the ground.






43. An underground layer of porous rock - sand - or other material that allows the movement of water between layers of nonporous rock or clay. Aquifers are frequently tapped for wells.






44. Ozone that exists in the trophosphere.






45. The condition in which - at ecosystem boundaries - there is greater species diversity and biological density than there is in the heart of ecological communities.






46. Gave the EPA power to set emission standards for major sources of noise - including transportation - machinery - and construction.






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






48. A severe tropical cyclone originating in the equatorial regions of the Atlantic Ocean or Caribbean Sea or eastern regions of the Pacific Ocean - traveling north - northwest - or northeast from its point of origin - and usually involving heavy rains.






49. When the energy released from waste incineration is used to generate electricity.






50. The process that occurs when two different species in a region compete and the better adapted species wins.
