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.

11. 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. ...






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






13. When companies are allowed to buy permits that allow them a certain amount of discharge of substances into certain environmental outlets. If they can reduce their amount of discharge - they are allowed to sell the remaining portion of their permit to






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






15. 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.






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






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






18. The edges of tectonic plates.






19. A symbiotic relationship in which one member is helped by the association and the other is harmed.






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






21. The phenomenon whereby the Earth's atmosphere traps solar radiation - caused by the presence in the atmosphere of gases such as carbon dioxide - water vapor - and methane that allow incoming sunlight to pass through - but absorb heat radiated back fr






22. Radioactive wastes that produce low levels of ionizing radiation.






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).

27. The act or process of transpiring - or releasing water vapor - especially through the stomata of plant tissue or the pores of the skin.






28. A bloom of dinoflagellates that causes reddish discoloration of coastal ocean waters. Certain dinoflagellates of the genus Gonyamfox produce toxins that kill fish and contaminate shellfish.

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






31. The third purest form of coal.






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






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






34. Can consist of hazardous waste - industrial solid waste - or municipal waste. Many types of solid waste provide a threat to human health and the environment.

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






41. The low-rainfall region that exists on the leeward (downwind) side of a mountain range. This rain shadow is the result of the mountain range's causing precipitation on the windward side.






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






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






44. A group of organisms of the same species that live in the same area.






45. The use of building materials - building placement - and design to passively collect solar energy that can be used to keep a building warm or cool.






46. When one species feeds on another.






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






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






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