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. 1. A mass of sand & gravel & or alluvium deposited on the bed of a stream & sea & or lake & or at the mouth of a stream 2. A unit of pressure & approximately equal to atmospheric pressure at sea level.






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






3. The area bordering a stream over which water spreads when the stream tops its channel banks.






4. A lake of lava & usually basaltic & in a volcanic caldera.






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






6. Materials that are found in nature that are useful or necessary for people to live.






7. The internal resistance to flow in a liquid.






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






9. The innermost zone of Earth. It consists of two parts & an outer liquid section and an inner solid section & both chiefly of iron and nickel with about 10 percent lighter elements. It is surrounded by the mantle.






10. The reflection of light on a given mineral's surface & classified by intensity and quality.






11. A continuous well-defined mass of material of sufficient ore content to make extraction economically feasible. compare mineral deposit.






12. A community of plants and/or animals and its physical environment & regarded as a unit.






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

15. The concept of a sequence of events involving the formation & alteration & destruction and reformation of rocks as a result of geologic processes.






16. A measure of the size of an earthquake in terms of the damage it causes.






17. (Greek-Aphrodite)named after the Roman goddess of love. It is the planet closest in size to Earth and the second planted from the Sun.






18. The amount of dissolved salt in water.






19. 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 &






20. The average weather conditions of an area over many years & as measured by temperature & wind speed & and precipitation.






21. Any accumulation of material & by settling from water or air & chemical precipitation & evaporation from solution & etc.






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






23. 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.






24. A flat & dry plain covered with short grass.






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






26. Bent rock strata.






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






28. 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.






29. Uranus is named after the Roman god of the sky. It is the seventh planet from the Sun.






30. The amount of dissolved salt in water.






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






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






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






34. Similar to a groin but built to keep sand out of a harbor entrance.






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






36. Heat transport by direct transfer of energy from one particle to another & without moving the particle to a new location.






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






38. Igneous. Antonym of intrusive. Synonym of volcanic. Pertaining to igneous rocks or features formed from lava released on the Earth's surface.






39. 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.






40. A guide to reading a map that typically contains distance scales & arrows indicating direction & and/or explanations of symbols used.

42. A mudflow composed chiefly of pyroclastic material on the flanks of a volcano.






43. Banks of sand and silt along stream bank built by deposition in small increments during successive floods.






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






45. The line separating land and water.






46. The green pigment in the cells of many plants that enables them to use sunlight to convert carbon dioxide and water into carbohydrates in the process called photosynthesis.






47. A waterway from open ocean into a lagoon.






48. 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.
