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 area in which a large number of windmills have been erected to generate electrical power.






2. The processes of weathering by which physical actions such as frost wedging break down a rock into fragments & involving no chemical change.






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






4. A sea wave produced by any large-scale & short duration disturbance on the seafloor & commonly a shallow submarine earthquake but possibly also a submarine slide or volcanic eruption.






5. A stone or boulder & glacially transported from place of origin and left in an area of different bedrock composition.






6. A blanket of wind-driven sand with an upper surface about a meter above ground level.






7. Temporary accumulations of sediments that collect between low and high water marks.






8. A curved belt of volcanic islands lying above a subduction zone.






9. A hole or basin cut into bedrock of a stream by the abrasive action of pebbles and sand swirled by turbulent stream flow.






10. A Hawaiian term for a basaltic lava flow with a smooth & or ropy surface.






11. A natural depression in the surface of the land caused by the collapse of the roof of a cavern or subterranean passage & generally occurring in limestone regions.






12. The sum of the processes that result in the wearing away or the progressive lowering of the Earth's surface by weathering & erosion & mass wasting & and transportation.






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






14. The distance between two successive wave crests or troughs.






15. The physical & chemical & and biological processes by which rock at or near the Earth's surface is broken down into smaller pieces.






16. Till deposited from main body of glacier during ablation.






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






18. An instrument used to measure the speed of wind.






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






20. A system that uses a constellation of 24 satellites & their ground stations & and individual GPS receivers to accurately locate points on Earth.






21. A substance that produces positively charged hydrogen ions (H+) when dissolved in water.






22. The low spot between two successive waves.






23. The southern portion of the late Paleozoic supercontinent known as Pangea. It means & literally 'Land of the Gonds' (a people of the Indian subcontinent).The supercontinent existed from Cambrian to Jurassic time & mainly composed of South America &






24. A method of sediment transport in which the turbulence of a fluid is able to keep particles supported in the fluid.






25. A narrow & elongate region in which one lithospheric plate descends relative to another.






26. The process of one plate descending beneath another.






27. A pillar formed as a stalactite and stalagmite meet.






28. A stone or boulder & glacially transported from place of origin and left in an area of different bedrock composition.






29. A waterway from open ocean into a lagoon.






30. 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.






31. The internal resistance to flow in a liquid.






32. A mound or ridge of sediment deposited by a glacier.






33. The naturally occurring material from which a mineral or minerals of economic value can be extracted at a profit.






34. The explosion of a dying giant or supergiant star.






35. The distance between two successive wave crests or troughs.






36. A layer of sedimentary rock; plural is strata.






37. A method of sediment transport in which the turbulence of a fluid is able to keep particles supported in the fluid.






38. The weak or 'soft' zone in the upper mantle just below the lithosphere & involved in plate movement and isostatic adjustments. It lies 70 to 100 km below the surface and may extend to a depth of 400 km.






39. Living in water.






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






41. Forms along a coast as wave erosion cuts through a headland.






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






43. Heat extracted from the Earth for use as an power source.






44. Deserts in zones of descending air between 25 degrees and 30 degrees north and south latitude.






45. The tendency of a moving object to continue in a straight line or a stationary object to remain in place.






46. The vertical distance between the crest and adjacent trough of a wave.






47. Occurs at the intersection of the water table with the ground surface.






48. Deserts in zones of descending air between 25 degrees and 30 degrees north and south latitude.






49. Any seismic wave that travels through the body of Earth & rather than along its surface.






50. A depression in the ground formed by the melting of a block of glacier ice buried or partially buried by drift.
