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. A plate boundary where two plates are moving toward each other.






2. 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.






3. 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.






4. The amount of sugar that the plants produce in photosynthesis and subtracting from it the amount of energy the plants need for growth maintenance - repair - and reproduction.






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






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






7. A bloom of dinoflagellates that causes reddish discoloration of coastal ocean waters. Certain dinoflagellates of the genus Gonyamfox produce toxins that kill fish and contaminate shellfish.






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






9. A nuclear reaction in which an atomic nucleus - especially a heavy nucleus such as an isotope of uranium - splits into fragments - usually two fragments of comparable mass - releasing from 100 million to several hundred million electron volts of ener






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






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






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






13. The unit used to describe the volume of fossil fuels.






14. The day-to-day variations in temperature - air pressure - wind - humidity - and precipitation mediated by the atmosphere in a given region.






15. The number of individuals of a population that inhabit a certain unit of land or water area.






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






17. The movement of individuals out of a population.






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






19. Organisms that consume secondary consumers or other tertiary consumers.






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






21. In tectonic plates - the site at which an oceanic plate is sliding under a continental plate.






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






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






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






25. Graphical representations of populations' ages.






26. The carrier organism through which pathogens can attack.






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






28. Living or derived from living things.






29. The edges of tectonic plates.






30. The use of building materials - building placement - and design to passively collect solar energy that can be used to keep a building warm or cool.






31. Pertaining to factors or things that are separate and independent from living things; nonliving.






32. The movement of individuals into a population.






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






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






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






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






37. 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.






38. A succession of organisms in an ecological community that constitutes a continuation of food energy from one organism to another as each consumes a lower member and - in turn - is preyed upon by a higher member.






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






40. When soil becomes water-logged and then dries out - and salt forms a layer on its surface.






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. When the majority of a building's occupants experience certain symptoms that vary with the amount of time spent in the building.






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






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






45. When the size of an organism's natural habitat is reduced - or when development occurs that isolates a habitat.






46. The development and introduction of new varieties of (mainly) wheat and rice that has increased yields per acre dramatically in countries since the 1960s.






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






48. The second-purest form of coal.






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






50. The process of fusing two nuclei.
