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. Where two plates collide to form mountains.






2. The great circle on the Earth's surface passing through The North and South Poles & which is considered 0 degrees longitude. The prime meridian passes through Greenwich & England & and is used as a reference point for measuring longitude east and w






3. A chuck of rock or dust in space.






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






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






6. Heat extracted from the Earth for use as an power source.






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






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






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






10. A substance that produces positively charged hydrogen ions (H+) when dissolved in water.






11. A broad & mound-like mass of glacier ice that usually spreads radially outward from a central zone.






12. One of several rock-forming minerals that contain at least 95% silica (quartz). and usually one or more other common elements.






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






14. Iron & aluminum & magnesium & manganese & and titanium. Ores of the abundant metals only need to be 3 - 5 times as metal-rich as average rock.






15. A conical volcano formed by the accumulation of pyroclastic debris around a vent.






16. The peak flow of water that tops the banks of a stream channel.






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






18. Water beneath the Earth's surface.






19. The process of mountain building.






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






21. A system involving continuous interaction of the solid Earth & the atmosphere & the oceans and living things.






22. The distance between two successive wave crests or troughs.






23. Geologic time expressed in years before the present.






24. The processes (mechanical and chemical) responsible for the wearing away & loosening & and dissolving of materials of the Earth's crust.






25. Lacking in rainfall & very dry.






26. Any seismic wave that travels through the body of Earth & rather than along its surface.






27. A coral reef separated from the mainland by a lagoon.






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






29. An instrument that merely indicates the occurrence of an earthquake.






30. A coral reef attached directly to the mainland.






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






32. The pattern of water circulation from the ocean to the atmosphere to the land and back to the ocean.






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






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






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






36. The theory that states that the present-day continents are the fragmented pieces of preexisting larger landmasses called supercontinents.






37. A region of high heat flow on the Earth's surface & thought to lie above a mantle plume .






38. The way in which a rock or mineral breaks in random patterns rather than cleaving






39. A planetary satellite.






40. A sedimentary rock made up of chemical sediments. Example: rock salt.






41. A study designed to collect critical data to be used for comparison or as a control in a later study.






42. The Earth's crust underlying the ocean basins which is formed at mid-oceanic ridges. It is typically 5 to 10 kilometers thick composed of basalt.






43. All of space and everything in it.






44. Distance over which wave-forming winds blow.






45. 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.






46. A flood that rises and falls very rapidly.






47. Containing moisture.






48. Temporary accumulations of sediments that collect between low and high water marks.






49. The zone below the zone of aeration in which all pore spaces are filled with water.






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