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 edges of tectonic plates.






2. 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.






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






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






5. Occurs when infection causes a change in the state of health.






6. Says that the entropy (disorder) of the universe is increasing. One corollary of the Second Law of thermodynamics is the concept that - in most energy transformations - a significant fraction of energy is lost to the universe as heat.






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






8. The dark - crumbly - nutrient-rich material that results from the decomposition of organic material.






9. The day-to-day variations in temperature - air pressure - wind - humidity - and precipitation mediated by the atmosphere in a given region.






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






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






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






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






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






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






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






17. A program funded by the federal government and a trust that's funded by taxes on chemicals; identifies pollutants and cleans up hazardous waste sites.






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






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






20. When physically treated sewage water is passed into a settling tank - where suspended solids settle out as sludge; chemically treated polymers may be added to help the suspended solids separate and settle out.






21. Any other species of fish - mammals - or birds that are caught that are not the target organism.






22. Energy at rest - or stored energy.






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






24. 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.






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






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






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






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






29. The more or less constant winds blowing in horizontal directions over the Earth's surface - as part of Hadley cells.






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






31. The energy of motion.






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






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






34. The atmospheric pressure conditions corresponding to the periodic warming of El Nino and cooling of La Nina.






35. When companies are allowed to buy permits that allow them a certain amount of discharge of substances into certain environmental outlets. If they can reduce their amount of discharge - they are allowed to sell the remaining portion of their permit to






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






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






38. 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).






39. The region draining into river system or other body of water.






40. Species that originate and live - or occur naturally - in an area or environment.






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






42. A process in which an organism is exposed to a toxin at different concentrations - and the dosage that causes the death of the organism is recorded.






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






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






45. The least pure coal.






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






47. Organisms that consume both producers and primary consumers.






48. Fish farming in which fish are caught in the wild and not raised in captivity for consumption.






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






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