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 molten core of the Earth.






2. 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






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






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






5. The random fluctuations in the frequency of the appearance of a gene in a small isolated population - presumably owing to chance - rather than natural selection.






6. 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.






7. The capacity to do work.






8. The solids that remain after the secondary treatment of sewage.






9. Soil composed of a mixture of sand - clay - silt - and organic matter.






10. Energy at rest - or stored energy.






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






12. A stable - mature community in a successive series that has reached equilibrium after having evolved through stages and adapted to its environment.






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






14. A soil horizon - horizon C is made up of larger pieces of rock that have not undergone much weathering.






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






16. Is equal to the number of deaths per 1 -000 members of the population in a year.






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






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






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






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






21. One that has never been cut; these forests have not been seriously disturbed for several hundred years.






22. 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.






23. The uppermost horizon of soil. It is primarily made up of organic material - including waste from organisms - the bodies of decomposing organisms - and live organisms.






24. A semiconductor device that converts the energy of sunlight into electric energy.






25. Ozone that exists in the trophosphere.






26. A fiscal policy that lowers taxes on income - including wages and profit - and raises taxes on consumption - particularly the unsustainable consumption of non-renewable resources.






27. 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.






28. The edges of tectonic plates.






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






30. Bacteria - virus - or other microorganisms that can cause disease.






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






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






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






34. The industry or occupation devoted to the catching - processing - or selling of fish - shellfish - or other aquatic animals.






35. 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.






36. Biotic and abiotic natural ecosystems.






37. When one species feeds on another.






38. The rocks and Earth that is removed when mining for a commercially valuable mineral resource.






39. 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.






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






41. Graphical representations of populations' ages.






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






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






44. 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.






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






46. Also known as plantations - these are planted and managed tracts of trees of the same age that are harvested for commercial use.






47. Organisms that consume both producers and primary consumers.






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






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






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