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 period of dryness & that when prolonged & causes damage to crops; a shortage of water.






2. The condition of equilibrium & comparable to floating & of units of the lithosphere above the asthenosphere.






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






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






5. An artificial hill formed by the debris of successive human settlements.






6. A plate boundary in which plates on opposite sides of the boundary move past each other in opposite directions. The San Andreas fault of California is a good example.






7. A rock that has crystallized from a molten state.






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






9. The process of one plate descending beneath another.






10. Plutonic. Antonym of extrusive. Pertaining to igneous rocks or features formed by the emplacement of magma in pre-existing rocks.






11. A type of thermal spring which ejects water intermittently with considerable force.






12. The process by which a binding & or cementing & agent is precipitated in spaces among individual particles of a deposit. Common cementing agents are calcite & quartz & and dolomite.






13. A broad & deep & generally straight furrow carved in bed rock by the abrasive action of debris embedded in a moving glacier. Larger and deeper than a glacial striation.






14. Reduction of pore space between individual particles as the result of overlying sediments or of tectonic movements.






15. Saturn is named after the Roman god of the harvest. It is the sixth planet from the Sun.






16. A large amount of gas and dust in space & spread out in an immense volume.






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






18. The process by which building stone & usually in blocks or sheets & is extracted from the Earth. radiation -- (Electromagnetic radiation) -- energy that travels through space in the form of waves without the intervention of matter & as in the transp






19. The solid innermost part of the core with a diameter of a little over 1 &200 km.






20. The low spot between two successive waves.






21. Glacial deposits laid down directly by glaciers or laid down in lakes & ocean & or streams as result of glacial activity.






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






23. 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.






24. The amount of material a stream carries in suspension.






25. The point on the Earth's surface that is directly above the focus of an earthquake.






26. The area immediately below the ground surface within which pore spaces are partially filled with water and partially filled with air.






27. Mars is named after the Roman god of war. It is the fourth planet from the Sun.






28. Evidence in rock of the presence of past life & such as a dinosaur bone & an ancient clam shell & or the footprint of a long-extinct animal as well as life history artifacts.






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






30. Open pit mining & typically for coal.






31. A commonly used scale of earthquake intensity.






32. Plutonic. Antonym of extrusive. Pertaining to igneous rocks or features formed by the emplacement of magma in pre-existing rocks.






33. Pluto is named after the Roman god of the Underworld. No longer considered a planet.






34. The mass of an object divided by its volume.






35. The partial or complete blocking from view of one object by another.






36. Long narrow beaches separated in many places from the mainland by lagoons.






37. The very small particles of dirt & soot & and other pollutants that are present in the air.






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






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






40. A sedimentary rock composed primarily of biogenic sediments.






41. A general term for a relatively hard layer of soil at or just below the ground surface & cemented by silica & iron oxide & calcium carbonate & or organic matter.






42. The solid innermost part of the core with a diameter of a little over 1 &200 km.






43. The upper horizons in a soil & through which gravitational moisture travels & removing soluble decomposition products.






44. 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.






45. A valley caused by extension of the Earth's crust. Its floor forms as a portion of the crust moves downward along normal faults.






46. 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.






47. A type of disintegration in which jointed rock is forced apart by the expansion of water as it freezes in fractures.






48. A sea level change due to change in load on Earth's crust.






49. A flood that rises and falls very rapidly.






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