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. In the geologic time scale a unit of time less than an era and greater than an epoch. Example: The Tertiary period was the earliest period in the Cenozoic era and included & among others & the Eocene epoch.






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






3. A large area with common features that set it apart from other areas.






4. The primary division of geologic time which are & from oldest to youngest & the Hadean & Archean & Proterozoic & and Phanerozoic eons.






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






6. 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.






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






8. Applies to igneous rocks that cool on the surface of the Earth & including beneath water; typically with small crystals due to the rapidity of cooling. Synonym of extrusive. Antonym of plutonic.






9. 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.






10. A unit of length used in sea navigation based on the length of 1 minute of arc on a great circle. On Earth & 1 minute of latitude.






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






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






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






14. A thickened elevated region of Earth's crust that is mainly (but not entirely) above sea level.






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 process by which salts accumulate in soil.






17. Where one plate slides beneath another plate as the two are pushed together & a subduction zone.






18. Deposition of fine mineral particles (silt) on the beds of streams or lakes.






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






20. A small & dust-bearing whirlwind.






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






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






23. Where two plates collide to form mountains.






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






25. A waterway from open ocean into a lagoon.






26. 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






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






28. Verifying assessments made from satellite data by doing direct & 'on-the ground' measurements.






29. Mercury is named after the Roman messenger of the gods. It is the closest to the Sun.






30. The two days of the year on which neither hemisphere is tilted toward or away from the sun.






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






32. A group of stars that appear to make a pattern in the sky. The Big Dipper is a constellation.






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






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






35. Rock formed from the accumulation of sediment & Which may consist of fragments and mineral grains of varying sizes from pre-existing rocks & remains or products of animals and plants & the products of chemical action & or mixtures of these.






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






37. Any object that revolves around another object in space.






38. 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.






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






40. The method of locating an epicenter by determining how far it lies from three widely separated seismographs.






41. An atmospheric shield providing the Earth with protection from ultra-violet rays which can cause sun burn & skin cancer and the destruction of the delicate plant life which supports the planet's food chain.






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






43. Imaginary lines on a map or globe that measure distance in degrees east or west of the prime meridian. Longitude lines extend vertically & from pole to pole on a globe.






44. A fracture or zone of fractures along the boundaries of tectonic plates where movement has taken place.






45. A person who makes maps.






46. (Latin- Sol & Greek- Helios)the closest star to Earth. It is a giant ball of gas without any solid surface.






47. Any solid material that has settled out of a state of suspension in liquid.






48. An abandoned meander .






49. (Latin- Sol & Greek- Helios)the closest star to Earth. It is a giant ball of gas without any solid surface.






50. The chronological sequence of units of Earth time.
