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






2. Any compound that releases hydrogen ions when dissolved in water. Also - a water solution that contains a surplus of hydrogen ions.






3. Also known as plantations - these are planted and managed tracts of trees of the same age that are harvested for commercial use.






4. Ozone that exists in the trophosphere.






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






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






7. Drilling a hole in the ground that's below the water table to hold waste.






8. 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.






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






10. The dosage level of a toxin at which a negative effect occurs.






11. When the energy released from waste incineration is used to generate electricity.






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






13. The molten core of the Earth.






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






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






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






17. A method of supplying irrigation water through tubes that literally drip water onto the soil at the base of each plant.






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






19. The uppermost horizon of soil. It is primarily made up of organic material - including waste from organisms - the bodies of decomposing organisms - and live organisms.






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






21. 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.






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






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






24. Bacteria or fungi that absorb nutrients from nonliving organic matter like plant material - the wastes of living organisms - and corpses. They convert these materials into inorganic forms.






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






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






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






28. An area in which a particular mineral is concentrated - mining -the excavation of the Earth for the purpose of extracting ore or minerals.






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






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






31. 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.






32. 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).






33. An animal that only consumes other animals.






34. A group of modern windmills.






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






36. 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.






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






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






39. The area or environment where an organism or ecological community normally lives or occurs.






40. The layer of the Earth between the crust and the core.






41. The region draining into river system or other body of water.






42. When each family in a community grows crops for themselves and rely on animal and human labor to plant and harvest crops.






43. 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






44. 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.






45. When one species feeds on another.






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






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






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






49. 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. ...






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