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.

1. 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.






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






3. 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.






4. The process of burning.






5. A system of vertical and horizontal air circulation predominating in tropical and subtropical regions and creating major weather patterns.






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






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






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






9. Being extinct or the process of becoming extinct.






10. An introduced - normative species.






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






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






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






14. Transition in species composition of a biological community - often following ecological disturbance of the community; the establishment of a biological community in any area virtually barren of life.






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






16. The third purest form of coal.






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






18. 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.






19. 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.






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






21. The bedrock - which lies below all of the other layers of soil - is referred to as the R horizon.






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






23. The vertical movement of a mass of matter due to heating and cooling; this can happen in both the atmosphere and Earth's mantle.






24. The energy of motion.






25. The carrier organism through which pathogens can attack.






26. The broad category under which selective cutting and shelter-wood cutting fall; selective deforestation.






27. 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.






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






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






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






31. 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






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






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






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






35. The A layer of soil is often referred to as topsoil and is most important for plant growth.






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






37. 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.






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






39. Any substance that has an LD50 - of 50 mg or less per kg of body weight.






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






41. 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.






42. The area or environment where an organism or ecological community normally lives or occurs.






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






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






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






46. 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






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






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






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






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