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. Formed when an organism is flattened (compressed) and a thin film of organic material from its body is left in the rock.






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






3. 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 &






4. Weathering processes that are the result of chemical reactions. Example: the transformation of orthoclase to kaolinite.






5. A seismic body wave that involves particle motion from side to side & perpendicular to the direction of wave propagation. S-waves are slower than P-waves and cannot travel through a liquid.






6. The persistence of wind-formed waves after wind ceases.






7. A region of high heat flow on the Earth's surface & thought to lie above a mantle plume .






8. 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.






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






10. Living on land.






11. That portion of the resources for a valuable mineral commodity that can be extracted from the Earth at a profit today.






12. A detailed mathematical description of the cause-and-effect relationships between events that can be used to predict or explain other such events.






13. In a stream & the volume of water passing through a channel in a given time.






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






15. A tool for measuring the relative clarity of water.






16. Synonym of intrusive. Antonym of volcanic. Applies to igneous rocks formed beneath the surface of the Earth; typically with large crystals due to the slowness of cooling.






17. A floating ice sheet extending across water from a land-based glacier.






18. The rock beneath the soil.






19. The initial point within the Earth that ruptures in an earthquake & directly below the epicenter. The point within the Earth which is the center of an earthquake & at which strain energy is first released and converted to elastic wave energy.






20. The zone below the zone of aeration in which all pore spaces are filled with water.






21. A coral reef attached directly to the mainland.






22. 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.






23. A slide involving a downward and usually sudden movement of newly detached segments of bedrock sliding or slipping over an inclined surface of weakness such as a bedding plane & fault plane & or joint surface.






24. The geologic eon lying between the Archean and Phanerozoic eons & beginning about 2.5 billion years ago and ending about 0.57 billion years ago.






25. He area from which a stream and its tributaries receives its water.






26. A dense & hot (sometimes incandescent) cloud of volcanic ash and gas produced in a Pelean eruption.






27. A lake in an abandoned meander.






28. A waste material that contaminates air & water & or soil.






29. The process of one plate descending beneath another.






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






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






32. The arrangement of rock units in the proper chronological order from youngest to oldest.






33. An area subject to dust storms & especially south central United States .






34. Deserts formed by blocking moisture-bearing winds with mountain barriers.






35. A rigid segment of the Earth's lithosphere that moves horizontally and adjoins other plates along zones of seismic activity. Plates may include portions of both continents and ocean basins.






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






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






38. An eon of geologic time extending from about 3.9 billion years to 2.5 billion years ago.






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






40. A giant structure that contains hundreds of billions of stars.






41. A group of islands; an expanse of water with scattered islands.






42. The areas of & in & or constituting a city.






43. An era of geologic time lasting from 570 to 245 million years ago.






44. The color of a mineral in its powdered form obtained from scraping a sample on a ceramic plate






45. Water beneath the Earth's surface.






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






47. The galaxy where Earth is located.






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






49. Large area of extremely flat ocean floor lying near a continent and generally over 4 km in depth.






50. 1. A low & bowl-shaped area of land surrounded by higher lands. 2. any large depression in which sediments are deposited.
