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.

2. Is the practice of planting bands of different crops across a hillside.






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






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






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






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






7. 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. ...






8. The result of chemical interaction with the bedrock that is typical of the action of both water and atmospheric gases.






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






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






11. Pollution that does not have a specific point of release - open -loop recycling -when materials are reused to form new products.

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






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






15. Species that originate and live - or occur naturally - in an area or environment.






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






17. The atmospheric pressure conditions corresponding to the periodic warming of El Nino and cooling of La Nina.






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






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






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






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

23. The right - as to fishing or to the use of a riverbed - of one who owns riparian land (the land adjacent to a river or stream).






24. The movement of individuals into a population.






25. The value of natural resources.






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






27. The condition in which - at ecosystem boundaries - there is greater species diversity and biological density than there is in the heart of ecological communities.






28. The process in which plants absorb ammonium (NH3) - ammonia ions (NH4+) - and nitrate ions (NO3) through their roots.






29. 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.






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






31. 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.






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






33. 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).






34. The movement of individuals out of a population.






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

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






40. 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.






41. Gave the EPA power to set emission standards for major sources of noise - including transportation - machinery - and construction.






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






43. A region of the ocean near the equator - characterized by calms - light winds - or squalls.






44. Fish farming in which fish are caught in the wild and not raised in captivity for consumption.






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






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






47. When grass is consumed by animals at a faster rate than it can regrow.






48. An organism such as a bacterium or protozoan - that obtains its nourishment through the oxidation of inorganic chemical compounds - as opposed to photosynthesis.
