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 naturally occurring inorganic solid that has a well-defined chemical composition and in which atoms are arranged in an ordered fashion.






2. Refers to rock or sediments made up primarily of broken fragments of pre-existing rocks or minerals.






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






4. 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 .






5. The line formed by the intersection of the axial plane of a fold with a bedding plane & marking where the bed shows its maximum curvature.






6. The straightening and/or deepening of a river channel.






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






8. 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.






9. The attractive force between two objects; its magnitude depends on their masses and the distance between them.






10. An instrument that detects & magnifies & and records vibrations of the Earth & especially earthquakes.






11. 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.






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






13. A segment of an active fault zone that has not experienced a major earthquake during a time period when most other segments of the zone have. They are generally regarded as having a higher potential for future earthquakes.






14. The sudden fall of one or more large pieces of a rock from a cliff.






15. Water beneath the Earth's surface.






16. A planetary satellite.






17. Distance over which wave-forming winds blow.






18. A minor tremor that precedes an earthquake. An increase in seismicity may signal that a major release of strain energy is about to occur.






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






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






21. Sediment formed by chemical precipitation from water. Example: halite precipitated as the result of the evaporation of sea water.






22. A volcanic mountain on the seafloor. If flat-topped & it is a guyot.






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






24. Glacial drift composed of rock fragments that range from clay to boulder size and randomly arranged without bedding.






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






26. The rigid outer shell of the Earth. It includes the crust and uppermost mantle and is on the order of 100 km in thickness.






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






28. Extending across a continent.






29. Soil conditions prevailing in area whose mean annual temperature is 0o C.






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






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






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






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






34. Pertaining to clastic material formed by volcanic explosion or aerial expulsion from a volcanic vent.






35. A commonly used measure of earthquake magnitude & based on a logarithmic scale. Each integral step on the scale represents a tenfold increase in the extent of ground shaking & as recorded on a seismograph.






36. The two days of the year on which the noon sun is directly overhead at either 23.5






37. The rise and fall of sea level caused by the gravitational pull of the Sun and Moon on the Earth.






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






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






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






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






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






43. An isolated & steep-sided & rocky mass or island just offshore from a rocky headland & usually on a shore platform.






44. A building that contains one or more telescopes.






45. The line formed by the intersection of the axial plane of a fold with a bedding plane & marking where the bed shows its maximum curvature.






46. A spring whose temperature is 6.5o C or more above mean annual air temperature.






47. A person who makes maps.






48. A spring whose temperature is 6.5o C or more above mean annual air temperature.






49. A hydrocarbon (coal or petroleum) that can be extracted from the Earth for use as a fuel. Fossil fuels are non-renewable energy sources.






50. Shapes & like mountains or hills that make up the Earth's surface.
