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 mound or ridge of sediment deposited by a glacier.






2. Named after the Roman god of the sea. It is the eighth planet from the Sun.






3. 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






4. A ridge of high water associated with a hurricane and which floods over the shore .






5. A sharp bend & loop or turn in a stream's course. When abandoned & it is called a meander scar or an oxbow.






6. The very slow & generally continuous downslope movement of soil and debris under the influence of gravity.






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






8. To preserve & or to avoid wasteful use.






9. The line that separates one drainage basin from another.






10. 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.






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






12. Extending across a continent.






13. The perpendicular or very steep descent of a stream.






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






15. A seismic body wave that involves particle motion & alternating compression and expansion & in the direction of wave propagation. It is the fastest seismic wave. compare S-wave .






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






17. Imaginary lines on a map or globe that measure distance in degrees north or south of the equator. Latitude lines extend horizontally & from east to west on a globe.






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






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






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






21. A portable time keeper with a mechanism for ensuring accuracy and adjusting itself & used for determining longitude at sea.






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






23. The remains of an extremely massive star pulled into a small volume by the force of gravity.






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






26. Any natural concentration of a valuable material in the Earth's crust & whether that material can be extracted profitably or not.






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






28. A type of volcanic eruption characterized by nuees ardentes and the development of lava domes.






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






30. The seaward edge of coast between low tide and effective wave action.






31. A supercontinent that existed from the Jurassic to Early Tertiary after splitting from Pangea; composed of Laurentia & Baltica & Avalonia & (modern North America & Scandinavia & Greenland & Western and Central Europe); eventually fragmented into Eur






32. The environment where a particular plant or animal is normally found.






33. Fossils formed when water containing minerals leaks into a mold. The minerals harden to form a copy of the original structure or organism.






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






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






36. A volcano in the shape of a flattened cone & broad and low & built by very fluid flows of basaltic lava.






37. Scratches & or small channels & gouged by glacier action. Occur on boulders & pebbles & and bedrock. Striations along bedrock indicate direction of ice movement.






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






39. The resistance of a mineral to scratching & as measured by the Mohs scale.






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






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






42. The part of the crust that directly underlies the continents and continental shelves. Averages about 35 km in thickness & but may be over 70 km thick under largest mountain ranges.






43. The speed at which water flows.






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






45. A portable time keeper with a mechanism for ensuring accuracy and adjusting itself & used for determining longitude at sea.






46. Woodland that usually gets at least 100 inches of rain each year.






47. The top of a wave.






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






49. The line separating land and water.






50. A river that is able to maintain its flow through a desert because of water received from outside the desert.
