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 compound that releases hydrogen ions when dissolved in water. Also - a water solution that contains a surplus of hydrogen ions.






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






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






4. 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






5. The result of graphing a dose-response analysis.






6. To convert or change into a vapor.






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






8. The part of the wide lower course of a river where its current is met by the tides.






9. The degree to which a substance is biologically harmful.






10. 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.






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






12. Organisms in the first stages of succession.






13. 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






14. 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.






15. The process in which animals (and plants!) breathe and give off carbon dioxide from cellular metabolism.






16. The structure obtained if we organize the amount of energy contained in producers and consumers in an ecosystem by kilocalories per square meter - from largest to smallest.






17. A group of modern windmills.






18. The process by which the concentration of toxic substances increases in each successive link in the food chain.






19. The second-purest form of coal.






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






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






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






23. 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.






24. 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.






25. A climate variation that takes place in the tropical Pacific about every three to seven years - for a duration of about one year.






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






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






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






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






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






31. The place where two plates abut each other.






32. The process of fusing two nuclei.






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






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






35. A symbiotic relationship in which both species benefit.






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






37. 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.






38. 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.






39. An animal that only consumes other animals.






40. When grass is consumed by animals at a faster rate than it can regrow.






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






42. 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.






43. States that matter can neither be created nor destroyed.






44. The cultivation of a single crop on a farm or in a region or country; a single - homogeneous culture without diversity or dissension.






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






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






47. Urban areas that heat up more quickly and retain heat more than do nonurban areas.






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






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






50. 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.
