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. Power generated using water.






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






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






4. The part of the mantle that lies just below the lithosphere.






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






6. The amount that the population would grow if there were unlimited resources in its environment.






7. Pertaining to factors or things that are separate and independent from living things; nonliving.






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






9. When ecological succession begins in a virtually lifeless area - such as the area behind a moving glacier.






10. Devices containing alkaline substances that precipitate out much of the sulfur dioxide from industrial plants.






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






12. Organisms in the first stages of succession.






13. Can consist of hazardous waste - industrial solid waste - or municipal waste. Many types of solid waste provide a threat to human health and the environment.






14. Land that's fit to be cultivated.






15. 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.






16. The carrier organism through which pathogens can attack.






17. Pollution that does not have a specific point of release - open -loop recycling -when materials are reused to form new products.






18. The process of fusing two nuclei.






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






20. The second-purest form of coal.






21. 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.






22. 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).






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






24. The random fluctuations in the frequency of the appearance of a gene in a small isolated population - presumably owing to chance - rather than natural selection.






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






26. The amount of sugar that the plants produce in photosynthesis and subtracting from it the amount of energy the plants need for growth maintenance - repair - and reproduction.






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






28. 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.






29. An animal that only consumes other animals.






30. Organisms that consume both producers and primary consumers.






31. The process by which - according to Darwin's theory of evolution - only the organisms best adapted to their environment tend to survive and transmit their genetic characteristics in increasing numbers to succeeding generations - while those less adap






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






33. The value of natural resources.






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






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






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






37. The edges of tectonic plates.






38. 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.






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






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






41. The A layer of soil is often referred to as topsoil and is most important for plant growth.






42. The thinning of the ozone layer over Antarctica (and to some extent - over the Arctic).






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






44. A cyclonic storm having winds ranging from approximately 48 to 121 km (30 to 75 miles) per hour.






45. The rocks and Earth that is removed when mining for a commercially valuable mineral resource.






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






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






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






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






50. Is equal to the number of deaths per 1 -000 members of the population in a year.
