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






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






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






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






5. The process in which soil bacteria convert ammonium (NH4+) to a form that can be used by plants; nitrate - or NO3.






6. The number of individuals of a population that inhabit a certain unit of land or water area.






7. The edges of tectonic plates.






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






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






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






11. 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






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






13. The outermost shell of the atmosphere - between the mesosphere and outer space - where temperatures increase steadily with altitude.






14. A climate variation that takes place in the tropical Pacific about every three to seven years - for a duration of about one year.






15. The coarsest soil - with particles 0.05 -2.0 mm in diameter.






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






17. States that matter can neither be created nor destroyed.






18. A stable - mature community in a successive series that has reached equilibrium after having evolved through stages and adapted to its environment.






19. The process in green plants and certain other organisms by which carbohydrates are synthesized from carbon dioxide and water using light as an energy source. Most forms of photosynthesis release oxygen as a byproduct.






20. The practice of alternating the crops grown on a piece of land - for example - corn one year - legumes for two years - and then back to corn.






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






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






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






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






25. The condition in which - at ecosystem boundaries - there is greater species diversity and biological density than there is in the heart of ecological communities.






26. 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.






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






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






29. Also known as transform faults - boundaries at which plates are moving past each other - sideways.






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






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






32. A species whose very presence contributes to an ecosystem's diversity and whose extinction would consequently lead to the extinction of other forms of life.






33. A layer of soil.






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






35. Any weathering that's caused by the activities of living organisms.






36. Open or forested areas built at the outer edge of a city.






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






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






39. 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.






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






41. The process of burning.






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






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






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






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






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






47. The accumulation of a substance - such as a toxic chemical - in various tissues of a living organism.






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






49. The observed effect of the Coriolis force - especially the deflection of an object moving above the Earth - rightward in the Northern Hemisphere - and leftward in the Southern Hemisphere.






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