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






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






3. Organisms in the first stages of succession.






4. A lowland area - such as a marsh or swamp - that is saturated with moisture - especially when regarded as the natural habitat of wildlife.






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






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






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






8. A fishing technique in which the ocean floor is literally scraped by heavy nets that smash everything in their path.






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






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






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






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






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






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






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






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






17. Energy at rest - or stored energy.






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






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






20. The degree to which a substance is biologically harmful.






21. 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.






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






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






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






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






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






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






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






29. The process in which animals (and plants!) breathe and give off carbon dioxide from cellular metabolism.






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






31. 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.






32. The right - as to fishing or to the use of a riverbed - of one who owns riparian land (the land adjacent to a river or stream).






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






34. In tectonic plates - the site at which an oceanic plate is sliding under a continental plate.






35. Organisms that derive energy from consuming nonliving organic matter.






36. Organisms that consume both producers and primary consumers.






37. 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.






38. 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.






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






40. Non-moving sources of pollution - such as factories.






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






42. Organisms that consume secondary consumers or other tertiary consumers.






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






44. When trees and crops are planted together - creating a mutualistic symbiotic relationship between them.






45. Land that's fit to be cultivated.






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






47. When one species feeds on another.






48. The removal of trees for agricultural purposes or purposes of exportation.






49. Sunlight.






50. The movement of individuals out of a population.
