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. 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.






2. When each family in a community grows crops for themselves and rely on animal and human labor to plant and harvest crops.






3. Organisms that consume primary consumers.






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






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






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






7. A waste product produced by the burning of coal.






8. The bedrock - which lies below all of the other layers of soil - is referred to as the R horizon.






9. Refers to resources - such as plants and animals - which can be regenerated if harvested at sustainable yields.






10. A usually triangular alluvial deposit at the mouth of a river.






11. Energy at rest - or stored energy.






12. Soil with particles 0.002 -0.05 mm in diameter.






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






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






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






16. Drilling a hole in the ground that's below the water table to hold waste.






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






18. When materials - such as plastic or aluminum - are used to rebuild the same product. An example of this is the use of the aluminum from aluminum cans to produce more aluminum cans.






19. The low-rainfall region that exists on the leeward (downwind) side of a mountain range. This rain shadow is the result of the mountain range's causing precipitation on the windward side.






20. Involves the sinking of shafts to reach underground deposits. In this type of mining - networks of tunnels are dug or blasted and humans enter these tunnels in order to manually retrieve the coal.






21. Refers to when farmers plant seeds without using a plow to turn the soil.






22. A basic substance; chemically - a substance that absorbs hydrogen ions or releases hydroxyl ions; in reference to natural water - a measure of the base content of the water.






23. The biological treatment of wastewater in order to continue to remove biodegradable waste.






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






25. The industry or occupation devoted to the catching - processing - or selling of fish - shellfish - or other aquatic animals.






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






27. The amount of time it takes for half of a radioactive sample to disappear.






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






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






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






31. 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.






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






33. An animal that only consumes other animals.






34. A hydrocarbon deposit - such as petroleum - coal - or natural gas - derived from living matter of a previous geologic time and used for fuel.






35. The removal of select trees in an area; this leaves the majority of the habitat in place and has less of an impact on the ecosystem.






36. Transition in species composition of a biological community - often following ecological disturbance of the community; the establishment of a biological community in any area virtually barren of life.






37. An underground layer of porous rock - sand - or other material that allows the movement of water between layers of nonporous rock or clay. Aquifers are frequently tapped for wells.






38. 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.






39. A place where a large quantity of a resource sits for a long period of time.






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






41. When mature trees are cut over a period of time (usually10 -20 years); this leaves mature trees - which can reseed the forest - in place.






42. Involves the removal of the Earth's surface all the way down to the level of the mineral seam.






43. Soil composed of a mixture of sand - clay - silt - and organic matter.






44. The result of chemical interaction with the bedrock that is typical of the action of both water and atmospheric gases.






45. 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.






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






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






48. Each of the feeding levels in a food chain.






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






50. When grass is consumed by animals at a faster rate than it can regrow.
