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. In fishing - the use of long lines that have baited hooks and will be taken by numerous aquatic organisms.






2. 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.






3. 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






4. Graphical representations of populations' ages.






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






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






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






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






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






10. 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.






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






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






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






14. When water rights are given to those who have historically used the water in a certain area.






15. When an area of vegetation is cut down and burned before being planted with crops.






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






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






18. Power generated using water.






19. The second-purest form of coal.






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






21. The least pure coal.






22. A high-speed - meandering wind current - generally moving from a westerly direction at speeds often exceeding 400 km (250 miles) per hour at altitudes of 15 to 25 km (10 to 15 miles).






23. The water from which a river rises; a source.






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






25. The raising of fish and other aquatic species in captivity for harvest.






26. The day-to-day use of environmental resources as food - clothing - and housing.






27. 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.






28. The cleanest-burning coal; almost pure carbon.






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






30. The process of burning.






31. A soil horizon; the layer below the O layer is called the A layer. The A layer is formed of weathered rock - with some organic material; often referred to as topsoil.






32. Organisms that consume primary consumers.






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






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






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. Ozone that exists in the trophosphere.






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






38. The part of the wide lower course of a river where its current is met by the tides.






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






40. A layer of soil.






41. Smog resulting from emissions from industry and other sources of gases produced by the burning of fossil fuels - especially coal.






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






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






44. 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.






45. 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.






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






47. 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.






48. The edges of tectonic plates.






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






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