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.

2. 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.






3. 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.






4. 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.






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






6. The second-purest form of coal.






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






8. Being extinct or the process of becoming extinct.






9. Organisms that consume secondary consumers or other tertiary consumers.






10. The process in green plants and certain other organisms by which carbohydrates are synthesized from carbon dioxide and water using light as an energy source. Most forms of photosynthesis release oxygen as a byproduct.






11. The carrier organism through which pathogens can attack.






12. The amount of time it takes for half of a radioactive sample to disappear.






13. 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.






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






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






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






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






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






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






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






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






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






24. The form petroleum takes when in the ground.






25. A lowland area - such as a marsh or swamp - that is saturated with moisture - especially when regarded as the natural habitat of wildlife.






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






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. The process by which the concentration of toxic substances increases in each successive link in the food chain.






29. Acid rain - acid hail - acid snow; all of which occur as a result of pollution in the atmosphere.






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






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






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






33. The structure obtained if we organize the amount of energy contained in producers and consumers in an ecosystem by kilocalories per square meter - from largest to smallest.






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






35. The number of children a couple must have in order to replace themselves in a population.






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






37. Says that energy can neither be created nor destroyed; it can only be transferred and transformed.






38. Any waste that poses a danger to human health; it must be dealt with in a different way from other types of waste.






39. The removal of trees for agricultural purposes or purposes of exportation.

43. The result of graphing a dose-response analysis.






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






45. A place where a large quantity of a resource sits for a long period of time.






46. A layer in a large body of water - such as a lake - that sharply separates regions differing in temperature - so that the temperature gradient across the layer is abrupt.






47. A program funded by the federal government and a trust that's funded by taxes on chemicals; identifies pollutants and cleans up hazardous waste sites.






48. 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






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






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