Subject : science
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. Living in water.






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






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






4. A time of unusual winds and currents in the Pacific Ocean . El Nino generally causes warmer-than-normal sea surface temperatures and increased rainfall and storm activity.






5. Open pit mining & typically for coal.






6. Heat transport by moving particles & and the thermal energy that they carry & to a new location.






7. A landscape that develops from the action of ground water in areas of easily soluble rocks. It is usually characterized by caves & underground drainage and sinkholes.






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






9. Jupiter is named after the Roman king of the gods. It is the fifth planet from the Sun.






10. A commonly used scale of earthquake intensity.






11. A floating ice sheet extending across water from a land-based glacier.






12. A large amount of gas and dust in space & spread out in an immense volume.






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






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






15. 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.






16. Heat transport by moving particles & and the thermal energy that they carry & to a new location.






17. A building that contains one or more telescopes.






18. A chuck of rock or dust in space.






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






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






21. 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






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






23. Long narrow beaches separated in many places from the mainland by lagoons.






24. 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






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






26. Property possessed by certain rocks of breaking with relative ease along parallel planes or nearly parallel surfaces in their crystal structures where the bonds are weakest.






27. A sedimentary rock composed of combustible matter derived from the partial decomposition of plant material.






28. The amount of dissolved salt in water.






29. The point on the Earth's surface that is directly above the focus of an earthquake.






30. An imaginary circle around the earth that represents the halfway mark between the North and South Poles and establishes the boundary between the Northern and Southern Hemispheres.






31. As applied to glacier ice & the process by which ice below the snow line is wasted by evaporation and melting.






32. 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.






33. 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.






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






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






36. A device containing a free-swinging magnetic needle that is attracted to Earth's magnetic North Pole. Used to determine direction of travel.






37. A tool for measuring the relative clarity of water.






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






39. The Sun with all the celestial bodies that revolve around it.






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






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






42. A floating ice sheet extending across water from a land-based glacier.






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






44. The current geologic era & which began 66.4 million years ago and continues to the present.






45. 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.
