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. A usually triangular alluvial deposit at the mouth of a river.






2. A process in which cold - often nutrient-rich - waters from the ocean depths rise to the surface.






3. The part of the Earth and its atmosphere in which living organisms exist or that is capable of supporting life.






4. The more or less constant winds blowing in horizontal directions over the Earth's surface - as part of Hadley cells.






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






6. The point at which 50 percent of the test organisms die from a toxin.






7. Organisms in the first stages of succession.






8. The energy of motion.






9. The second-purest form of coal.






10. Soil composed of a mixture of sand - clay - silt - and organic matter.






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






12. 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.






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






14. Ozone that exists in the trophosphere.






15. A succession of organisms in an ecological community that constitutes a continuation of food energy from one organism to another as each consumes a lower member and - in turn - is preyed upon by a higher member.






16. In a sewage treatment plant - the initial filtration that is done to remove debris such as stones - sticks - rags - toys - and other objects that were flushed down the toilet.






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






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






19. The place where two plates abut each other.






20. Involves the removal of the Earth's surface all the way down to the level of the mineral seam.






21. Calculating risk - or the degree of likelihood that a person will become ill upon exposure to a toxin or pathogen.






22. The movement of individuals into a population.






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






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






25. The process that occurs when two different species in a region compete and the better adapted species wins.






26. 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.






27. An organism that is capable of converting radiant energy or chemical energy into carbohydrates.






28. Nets that are dragged through the water and indiscriminately catch everything in their path.






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






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






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






32. Poor nutrition that results from an insufficient or poorly balanced diet.






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






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






35. The liquid that percolates to the bottom of a landfill.






36. The solids that remain after the secondary treatment of sewage.






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






38. Biotic and abiotic natural ecosystems.






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






40. A specific location from which pollution is released; an example of a point source location is a factory where wood is being burned.






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






42. A severe tropical cyclone originating in the equatorial regions of the Atlantic Ocean or Caribbean Sea or eastern regions of the Pacific Ocean - traveling north - northwest - or northeast from its point of origin - and usually involving heavy rains.






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






44. To convert or change into a vapor.






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






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






47. Organisms that reproduce early in life and often and have a high capacity for reproductive growth.






48. An organism that must obtain food energy from secondary sources - for example - by eating plant or animal matter.






49. 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.






50. 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).
