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. Organisms in the first stages of succession.






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






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






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






5. An opening in the Earth's crust through which molten lava - ash - and gases are ejected.






6. 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).






7. The conversion of atmospheric nitrogen into compounds - such as ammonia - by natural agencies or various industrial processes.






8. When photochemical smog - NOx compounds - VOCs - and ozone combine to form smog with a brownish hue.






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






10. A system of vertical and horizontal air circulation predominating in tropical and subtropical regions and creating major weather patterns.






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






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






13. To convert or change into a vapor.






14. The process of fusing two nuclei.






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






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






17. Areas where cutting has occurred and a new - younger forest has arisen.






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






19. Non-moving sources of pollution - such as factories.






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






21. The movement of individuals into a population.






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






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






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






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






26. The maintenance of a species or ecosystem in order to ensure their perpetuation - with no concern as to their potential monetary value






27. A group of modern windmills.






28. 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.






29. The second-purest form of coal.






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






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






32. 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.






33. 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.






34. Urban areas that heat up more quickly and retain heat more than do nonurban areas.






35. 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.






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






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






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






39. 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.






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






41. 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






42. A platinum - coated device that oxidizes most of the VOCs and some of the CO that would otherwise be emitted in exhaust - converting them to CO2.






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






44. 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.






45. Smog resulting from emissions from industry and other sources of gases produced by the burning of fossil fuels.






46. 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.






47. The amount of the Earth's surface that's necessary to supply the needs of - and dispose of the waste from a particular population.






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






49. 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.






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