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. 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






2. A model that's used to predict population trends based on the birth and death rates as well as economic status of a population.






3. The process by which specialized bacteria (mostly anaerobic bacteria) convert ammonia to NOy NO2 - and N2 and release it back to the atmosphere.






4. The removal of all of the trees in an area.






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






6. The form petroleum takes when in the ground.






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






8. When materials - such as plastic or aluminum - are used to rebuild the same product. An example of this is the use of the aluminum from aluminum cans to produce more aluminum cans.






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






10. In tectonic plates - the site at which an oceanic plate is sliding under a continental plate.






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






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






13. A group of modern windmills.






14. The process in which animals (and plants!) breathe and give off carbon dioxide from cellular metabolism.






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






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






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






18. Organisms that are capable of interbreeding with one another and incapable of breeding with other species.






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






20. 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






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






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






23. Organisms that consume both producers and primary consumers.






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






25. An underground layer of porous rock - sand - or other material that allows the movement of water between layers of nonporous rock or clay. Aquifers are frequently tapped for wells.






26. The capacity to do work.






27. The process of soil particles being carried away by wind or water. Erosion moves the smaller particles first and hence degrades the soil to a coarser - sandier - stonier texture.






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






29. A symbiotic relationship in which both species benefit.






30. The point at which 50 percent of the test organisms show a negative effect from a toxin.






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






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






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






34. 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).






35. Bacteria - virus - or other microorganisms that can cause disease.






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






37. 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.






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






39. The day-to-day variations in temperature - air pressure - wind - humidity - and precipitation mediated by the atmosphere in a given region.






40. The cultivation of a single crop on a farm or in a region or country; a single - homogeneous culture without diversity or dissension.






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






42. An introduced - normative species.






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






44. The result of vibrations (often due to plate movements) deep in the Earth that release energy. They often occur as two plates slide past one another at a transform boundary.






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






46. When one species feeds on another.






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






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






49. 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.






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