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






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






3. 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






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






5. The place where two plates abut each other.






6. Open or forested areas built at the outer edge of a city.






7. A soil horizon; the layer below the O layer is called the A layer. The A layer is formed of weathered rock - with some organic material; often referred to as topsoil.






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






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






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






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






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






13. A process in which rows of crops are plowed across the hillside; this prevents the erosion that can occur when rows are cut up and down on a slope. ...






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






15. The value of natural resources.






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






17. Any water that has been used by humans. This includes human sewage - water drained from showers - tubs - sinks - dishwashers - washing machines - water from industrial processes - and storm water runoff.






18. Involves the removal of the Earth's surface all the way down to the level of the mineral seam.






19. The process of burning.






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






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






22. The edges of tectonic plates.






23. Power generated using water.






24. Creating flat platforms in the hillside that provide a level planting surface - which reduces soil runoff from the slope.






25. Biotic and abiotic natural ecosystems.






26. The conversion of atmospheric nitrogen into compounds - such as ammonia - by natural agencies or various industrial processes.






27. When ecological succession begins in a virtually lifeless area - such as the area behind a moving glacier.






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






29. Change in the genetic composition of a population during successive generations as a result of natural selection acting on the genetic variation among individuals and resulting in the development of new species.






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






31. A method of supplying irrigation water through tubes that literally drip water onto the soil at the base of each plant.






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






33. 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.






34. The process in which soil becomes saltier and saltier until - finally - the salt prevents the growth of plants. Salinization is caused by irrigation because salts brought in with the water remain in the soil as water evaporates.






35. The unit used to describe the volume of fossil fuels.






36. The amount of energy that plants pass on to the community of herbivores in an ecosystem.






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






38. The number of individuals of a population that inhabit a certain unit of land or water area.






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






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






41. 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.






42. 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.






43. Urban areas that heat up more quickly and retain heat more than do nonurban areas.






44. 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.






45. 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






46. The degree to which a substance is biologically harmful.






47. An introduced - normative species.






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






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






50. Any other species of fish - mammals - or birds that are caught that are not the target organism.
