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. A major drainage divide separating the drainage to one ocean from another.






2. A process by which salts accumulate in soil.






3. The most recent eon of geologic time beginning 570 million years ago and continuing to the present.






4. Any object that revolves around another object in space.






5. Any solid material that has settled out of a state of suspension in liquid.






6. The generally dark & more or less stable part of the organic matter in a soil & so well decomposed that the original sources cannot be identified.






7. The closest star to Earth besides the sun. It is approximately 4 light years away.






8. The theory that states that the present-day continents are the fragmented pieces of preexisting larger landmasses called supercontinents.






9. The way in which a rock or mineral breaks in random patterns rather than cleaving






10. Pertaining to or composed of granite & a coarse-grained igneous rock dominated by light-colored minerals & consisting of about 50 percent orthoclase & 25 percent quartz & and balance of feldspars and ferromagnesian silicates. Granite is commonly foun






11. Where two plates are moving in opposite directions as in a mid-ocean ridge.






12. The surface between the zone of saturation and the zone of aeration.






13. A narrow strip of land that has water on either side and connects two larger bodies of water.






14. Surficial mining & in which the valuable rock is exposed by removal of overlying rock or soil.






15. The accumulation of material in layers or beds.






16. The effect of water and carbon dioxide absorbing outgoing infrared radiation & raising a system's temperature. The term is generally used with reference to the Earth's temperature & although it can also be applied to other systems & such as greenhous






17. The process of mountain building.






18. The portion of the continental margin that lies between the abyssal plain and the continental slope. The continental rise is underlain by crustal rocks of the ocean basin.






19. A naturally occurring inorganic solid that has a well-defined chemical composition and in which atoms are arranged in an ordered fashion.






20. The prediction that climate will warm as a result of the addition to the atmosphere of humanly produced greenhouse gases.






21. A narrow strip of land along the margin of the ocean extending inland for a variable distance from low water mark.






22. A hot & gaseous & self-luminous celestial body & as the Sun.






23. A low & nearly flat accumulation of sediment deposited at the mouth of a river or stream & commonly triangular or fan-shaped.






24. The low spot between two successive waves.






25. The method of locating an epicenter by determining how far it lies from three widely separated seismographs.






26. The acidity in rain due to gases from internal combustion engines and coal- and oil-burning power plants.






27. A post of dripstone growing up from a cave floor.






28. Molten rock & containing dissolved gases and suspended solid particles. At the Earth's surface & magma is known as lava.






29. A large area of flat or nearly flat land.






30. The peak flow of water that tops the banks of a stream channel.






31. An instrument that detects & magnifies & and records vibrations of the Earth & especially earthquakes.






32. A vent on the seafloor from which hydrothermal fluids are emitted. Upon mixing with seawater and cooling & the fluids precipitate a cloud of fine-grained sulfide minerals that resembles a cloud of black smoke.






33. Any place where bedrock is visible on the surface of the Earth.






34. Imaginary lines on a map or globe that measure distance in degrees east or west of the prime meridian. Longitude lines extend vertically & from pole to pole on a globe.






35. The sudden fall of one or more large pieces of a rock from a cliff.






36. Elongated rises on the ocean floor where basalt periodically erupts & forming new oceanic crust.






37. The current geologic era & which began 66.4 million years ago and continues to the present.






38. A steep or vertical cliff & either above or below sea level.






39. A minor tremor that precedes an earthquake. An increase in seismicity may signal that a major release of strain energy is about to occur.






40. A mass of ice & formed by the recrystallization of snow & that flows forward & or has flowed at some time in the past.






41. Objects revolving around the sun that are too small and too numerous to be considered planets.






42. A sedimentary rock made up of chemical sediments. Example: rock salt.






43. An individual grain or constituent of a rock.






44. An eruption of lava that takes place from a fracture & usually without producing a cone.






45. A cavity in a lava & formed by the entrapment of a gas bubble during solidification of the lava.






46. A process of erosion in which wind carries off particles of dust and sand.






47. An area of land that delivers runoff water & sediment & and dissolved substances to surface water bodies & such as rivers or lakes. All watersheds consist of boundaries & a basin and collection areas.






48. A large volume of dust-sized particles lifted high into the atmosphere.






49. The presence of layers in some rocks caused by parallel alignment of minerals.






50. Rock formed from the accumulation of sediment & Which may consist of fragments and mineral grains of varying sizes from pre-existing rocks & remains or products of animals and plants & the products of chemical action & or mixtures of these.
