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. Refers to resources - such as plants and animals - which can be regenerated if harvested at sustainable yields.






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






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






4. An animal that only consumes other animals.






5. The carrier organism through which pathogens can attack.






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






7. A fishing technique in which the ocean floor is literally scraped by heavy nets that smash everything in their path.






8. The number of children an average woman will bear during her lifetime; this information is based on an analysis of data from preceding years in the population in question.






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






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






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






12. Energy at rest - or stored energy.






13. The process in which soil becomes saltier and saltier until - finally - the salt prevents the growth of plants. Salinization is caused by irrigation because salts brought in with the water remain in the soil as water evaporates.






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






15. Radioactive wastes that produce high levels of ionizing radiation.






16. 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.






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






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






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






20. Organisms that consume primary consumers.






21. The maximum population size that can be supported by the available resources in a region.






22. A basic substance; chemically - a substance that absorbs hydrogen ions or releases hydroxyl ions; in reference to natural water - a measure of the base content of the water.






23. The edges of tectonic plates.






24. The process of burning.






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






26. 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.






27. When the size of an organism's natural habitat is reduced - or when development occurs that isolates a habitat.






28. 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.






29. Close - prolonged associations between two or more different organisms of different species that may - but do not necessarily benefit the members.






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






31. The third purest form of coal.






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






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






34. A fiscal policy that lowers taxes on income - including wages and profit - and raises taxes on consumption - particularly the unsustainable consumption of non-renewable resources.






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






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






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






38. A semiconductor device that converts the energy of sunlight into electric energy.






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






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






41. A soil horizon - horizon C is made up of larger pieces of rock that have not undergone much weathering.






42. A long - relatively narrow island running parallel to the mainland-built up by the action of waves and currents and serving to protect the coast from erosion by surf and tidal surges.






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






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






45. 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).






46. The management of forest plantations for the purpose of harvesting timber.






47. Pollutants that are released directly into the lower atmosphere.






48. A cooling of the ocean surface off the western coast of South America - occurring periodically every 4 to 12 years and affecting Pacific and other weather patterns.






49. Power generated using water.






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