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.

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






7. Organisms that reproduce later in life - produce fewer offspring - and devote significant time and energy to the nurturing of their offspring.






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






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






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






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






12. 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.

14. Organisms in the first stages of succession.






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






16. Being extinct or the process of becoming extinct.






17. Air currents caused by the vertical movement of air due to atmospheric heating and cooling.






18. A plate boundary at which plates are moving away from each other. This causes an upwelling of magma from the mantle to cool and form new crust.






19. The fraction of solar energy that is reflected back into space.






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






21. A plate boundary where two plates are moving toward each other.






22. Energy at rest - or stored energy.






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






24. When trees and crops are planted together - creating a mutualistic symbiotic relationship between them.






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






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






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






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






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






30. A waste product produced by the burning of coal.






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






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






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






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






35. 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.






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






37. Each of the feeding levels in a food chain.






38. 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






39. A process in which an organism is exposed to a toxin at different concentrations - and the dosage that causes the death of the organism is recorded.






40. 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.






41. Says that the entropy (disorder) of the universe is increasing. One corollary of the Second Law of thermodynamics is the concept that - in most energy transformations - a significant fraction of energy is lost to the universe as heat.






42. The carrier organism through which pathogens can attack.






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






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






45. A climate variation that takes place in the tropical Pacific about every three to seven years - for a duration of about one year.






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






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






48. 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.






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






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