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






2. 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.






3. Energy at rest - or stored energy.






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






5. A symbiotic relationship in which both species benefit.






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






7. 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.






8. The management of forest plantations for the purpose of harvesting timber.






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






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






11. A group of modern windmills.






12. The number of live births per 1 -000 members of the population in a year.






13. The third purest form of coal.






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






15. Formed from populations of different species occupying the same geographic area.






16. A layer of soil.






17. To convert or change into a vapor.






18. A process that allows the organic material in solid waste to be decomposed and reintroduced into the soil - often as fertilizer.






19. When the majority of a building's occupants experience certain symptoms that vary with the amount of time spent in the building.






20. 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. ...






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






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






23. A tank filled with aerobic bacteria that's used to treat sewage.






24. The process in which soil bacteria convert ammonium (NH4+) to a form that can be used by plants; nitrate - or NO3.






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






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






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






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






29. The amount that the population would grow if there were unlimited resources in its environment.






30. The movement of individuals into a population.






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






32. An organism that must obtain food energy from secondary sources - for example - by eating plant or animal matter.






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






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






35. The energy of motion.






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






37. Graphical representations of populations' ages.






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






39. Power generated using water.






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






41. Using strategies to reduce the amount of risk (the degree of likelihood that a person will become ill upon exposure to a toxin or pathogen).






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






43. Pollutants that are released directly into the lower atmosphere.






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






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






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






47. 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.






48. The least pure coal.






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






50. The gaseous mass or envelope surrounding a celestial body - especially the one surrounding the Earth - which is retained by the celestial body's gravitational field.
