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 least pure coal.






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






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






4. A complex of interrelated food chains in an ecological community.






5. A hydrocarbon deposit - such as petroleum - coal - or natural gas - derived from living matter of a previous geologic time and used for fuel.






6. When mature trees are cut over a period of time (usually10 -20 years); this leaves mature trees - which can reseed the forest - in place.






7. The region draining into river system or other body of water.






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






9. When populations are well below the size dictated by the carrying capacity of the region they live in - they will grow exponentially - but as they approach the carrying capacity - their growth rate will decrease and the size of the population will ev






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






11. An erosion-resistant marine ridge or mound consisting chiefly of compacted coral together with algal material and biochemically deposited magnesium and calcium carbonates.






12. The outer part of the Earth - consisting of the crust and upper mantle - approximately 100 km (62 miles) thick.






13. The dosage level of a toxin at which a negative effect occurs.






14. The part of the Earth and its atmosphere in which living organisms exist or that is capable of supporting life.






15. Ozone that exists in the trophosphere.






16. 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.






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






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






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. An effect that results from long -term exposure to low levels of toxin.






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






22. A cooling of the ocean surface off the western coast of South America - occurring periodically every 4 to 12 years and affecting Pacific and other weather patterns.






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






24. In tectonic plates - the site at which an oceanic plate is sliding under a continental plate.






25. When one species feeds on another.






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. The more or less constant winds blowing in horizontal directions over the Earth's surface - as part of Hadley cells.






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






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






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






31. 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.






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






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






34. 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.






35. 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.






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






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






38. The removal of all of the trees in an area.






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






40. An organism that obtains organic food molecules without eating other organisms or substances derived from other organisms. autotrophs use energy from the sun or from the oxidation of inorganic substances to make organic molecules from inorganic ones.






41. The form petroleum takes when in the ground.






42. Refers to when farmers plant seeds without using a plow to turn the soil.






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






44. Organisms that consume both producers and primary consumers.






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






46. 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.






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






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






49. Soil with particles 0.002 -0.05 mm in diameter.






50. The energy of motion.
