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 lowland area - such as a marsh or swamp - that is saturated with moisture - especially when regarded as the natural habitat of wildlife.






2. The total sum of a species' use of the biotic and abiotic resources in its environment.






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






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






5. 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.






6. The right - as to fishing or to the use of a riverbed - of one who owns riparian land (the land adjacent to a river or stream).






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






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






9. The energy of motion.






10. When water rights are given to those who have historically used the water in a certain area.






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






12. Calculating risk - or the degree of likelihood that a person will become ill upon exposure to a toxin or pathogen.






13. The second-purest form of coal.






14. Power generated using water.






15. The least pure coal.






16. A high-speed - meandering wind current - generally moving from a westerly direction at speeds often exceeding 400 km (250 miles) per hour at altitudes of 15 to 25 km (10 to 15 miles).






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






18. 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.






19. Non-moving sources of pollution - such as factories.






20. When photochemical smog - NOx compounds - VOCs - and ozone combine to form smog with a brownish hue.






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






22. When materials - such as plastic or aluminum - are used to rebuild the same product. An example of this is the use of the aluminum from aluminum cans to produce more aluminum cans.






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






24. A layer of soil.






25. 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.






26. 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.






27. 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.






28. The raising of fish and other aquatic species in captivity for harvest.






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






30. 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






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






32. The atmospheric pressure conditions corresponding to the periodic warming of El Nino and cooling of La Nina.






33. In fishing - the use of long lines that have baited hooks and will be taken by numerous aquatic organisms.






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






35. The molten core of the Earth.






36. The result of chemical interaction with the bedrock that is typical of the action of both water and atmospheric gases.






37. When trees and crops are planted together - creating a mutualistic symbiotic relationship between them.






38. A region of the ocean near the equator - characterized by calms - light winds - or squalls.






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






40. 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.






41. Organisms in the first stages of succession.






42. Organisms that reproduce early in life and often and have a high capacity for reproductive growth.






43. The process of fusing two nuclei.






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






45. The dark - crumbly - nutrient-rich material that results from the decomposition of organic material.






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






47. A usually triangular alluvial deposit at the mouth of a river.






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






49. The carrier organism through which pathogens can attack.






50. The maximum population size that can be supported by the available resources in a region.
