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 opening in the Earth's crust through which molten lava - ash - and gases are ejected.






2. Organisms that reproduce later in life - produce fewer offspring - and devote significant time and energy to the nurturing of their offspring.






3. The broad category under which selective cutting and shelter-wood cutting fall; selective deforestation.






4. The number of live births per 1 -000 members of the population in a year.






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






6. The management or regulation of a resource so that its use does not exceed the capacity of the resource to regenerate itself.






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






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






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






10. Energy at rest - or stored energy.






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






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






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






14. To convert or change into a vapor.






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






16. Organisms that consume primary consumers.






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






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






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






20. A process in which cold - often nutrient-rich - waters from the ocean depths rise to the surface.






21. 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.






22. The conversion of atmospheric nitrogen into compounds - such as ammonia - by natural agencies or various industrial processes.






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






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






25. The uppermost horizon of soil. It is primarily made up of organic material - including waste from organisms - the bodies of decomposing organisms - and live organisms.






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






27. A climate variation that takes place in the tropical Pacific about every three to seven years - for a duration of about one year.






28. 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.






29. 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.






30. The movement of individuals out of a population.






31. The value of natural resources.






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






33. Piles of gangue - which is the waste material that results from mining.






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






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






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






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






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






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






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






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






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






43. 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.






44. Formed from populations of different species occupying the same geographic area.






45. 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).






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






47. 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






48. Land that's fit to be cultivated.






49. The process by which the concentration of toxic substances increases in each successive link in the food chain.






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