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






2. A layer of soil.






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






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. 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).






6. Piles of gangue - which is the waste material that results from mining.






7. The process by which - according to Darwin's theory of evolution - only the organisms best adapted to their environment tend to survive and transmit their genetic characteristics in increasing numbers to succeeding generations - while those less adap






8. The least pure coal.






9. This category includes organisms that consume producers (plants and algae).






10. Biotic and abiotic natural ecosystems.






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






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






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






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






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






16. 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.






17. The place where two plates abut each other.






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






19. 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.






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






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






22. Power generated using water.






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






24. Acid rain - acid hail - acid snow; all of which occur as a result of pollution in the atmosphere.






25. 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.






26. An intensification of the Greenhouse Effect due to the increased presence of heat-trapping gases in the atmosphere.






27. 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.






28. When each family in a community grows crops for themselves and rely on animal and human labor to plant and harvest crops.






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






30. The amount that the population would grow if there were unlimited resources in its environment.






31. A fishing technique in which the ocean floor is literally scraped by heavy nets that smash everything in their path.






32. The point at which 50 percent of the test organisms show a negative effect from a toxin.






33. A hydrocarbon that forms as sediments are buried and pressurized.






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






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






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






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






38. 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.






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






40. A model that's used to predict population trends based on the birth and death rates as well as economic status of a population.






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






42. Organisms that derive energy from consuming nonliving organic matter.






43. A long - relatively narrow island running parallel to the mainland-built up by the action of waves and currents and serving to protect the coast from erosion by surf and tidal surges.






44. 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.






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






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






47. 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.






48. The removal of trees for agricultural purposes or purposes of exportation.






49. Any noise that causes stress or has the potential to damage human health.






50. The use of devices - such as solar panels - to collect - focus - transport - or store solar energy.
