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. Either the northern or southern half of the Earth as divided by the equator & or the eastern or western half as divided by a meridian.






2. A thick layer of soil.






3. The closest galaxy to the Milky way. It is approximately 2 million light-years away.






4. Any form of water & such as rain & sleet & or snow & that falls to Earth's surface.






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






6. (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.






7. 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.






8. A large & basin-shaped volcanic depression & more or less circular in form. Typically steep-sided & found at the summit of a shield volcano.






9. A protective wall built offshore and usually parallel to the shore.






10. (Latin- Terra & Greek- Gaia) Earth is named after the ancient Germanic Goddess of the soil. It is the third planet from the Sun.






11. Living parts of the environment that can renew or replace themselves.






12. The portion of the continental margin that extends as a gently sloping surface from the shoreline seaward to a marked change in slope at the top of the continental slope . Seaward depth averages about 130 m.






13. A downward distortion or dimple in the water table that forms as a well pumps water faster than it can flow through the aquifer.






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






15. A dense & hot (sometimes incandescent) cloud of volcanic ash and gas produced in a Pelean eruption.






16. A term applied to large areas of basaltic lava presumably extruded from fissures.






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






18. Sediments produced directly by the life processes of plants or animals.






19. Living on land.






20. The low spot between two successive waves.






21. A division of geologic time next smaller than the eon and larger than a period. Example: The Paleozoic era is in the Phanerozoic eon and includes & among others & the Devonian period.






22. The breaking away of ice from the front of the glacier when it ends in a lake or an ocean. Produces icebergs.






23. An astronomical instrument for measuring angles & primarily altitude of celestial bodies to determine latitude.






24. 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.






25. The naturally occurring material from which a mineral or minerals of economic value can be extracted at a profit.






26. Mountains & characterized by extensive folding and thrust faulting & that form at convergent plate boundaries on continents.






27. The precipitation that runs directly off the surface to stream or body of standing water.






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






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






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






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






32. A general term including both oil and natural gas.






33. To preserve & or to avoid wasteful use.






34. 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.






35. The dust-sized & sharp-edged & glassy particles resulting from an explosive volcanic eruption.






36. The zones of seismic activity long which plates are in contact.






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






38. A geometrical form taken by a mineral & giving external expression to orderly internal atomic arrangement.






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






40. A sea wave produced by any large-scale & short duration disturbance on the seafloor & commonly a shallow submarine earthquake but possibly also a submarine slide or volcanic eruption.






41. The science that deals with the study of the planet Earth--the materials of which it is made & the processes that act to change these materials from one form to another & and the history recorded by these materials; the forces acting to deform the ou






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






43. A worldwide change in sea level & such as caused by melting glaciers.






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






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






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






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