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. The internal resistance to flow in a liquid.






2. Weathering processes that are the result of chemical reactions. Example: the transformation of orthoclase to kaolinite.






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






4. The speed at which water flows.






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






6. A steep-sided rounded extrusion of highly viscous lava squeezed out from a volcano and forming a dome-shaped or bulbous mass above and around the volcanic vent. The structure generally develops inside a volcanic crater.






7. A building that contains one or more telescopes.






8. A narrow strip of land that has water on either side and connects two larger bodies of water.






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






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






11. A sea level change due to change in load on Earth's crust.






12. A post of dripstone growing up from a cave floor.






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






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






15. A pillar formed as a stalactite and stalagmite meet.






16. Swamp that forms in the low lying flood plain behind a levee.






17. The speed at which water flows.






18. 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.






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






20. A cyclical pattern of movement in a fluid body such as the ocean & the atmosphere & or the Earth's mantle & driven by density variations which in turn are the result of differences in temperature from one part of the fluid to another.






21. Lies half way between the north and south magnetic poles.






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






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






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






25. A narrow & elongate region in which one lithospheric plate descends relative to another.






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






27. An eruption of lava that takes place from a fracture & usually without producing a cone.






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






29. That portion of the Earth below the crust and reaching to about 2 &780 km & where a transition zone of about 100 km thickness separates it from the core.






30. An aggregate of one or more minerals in varying proportions.






31. The study of earthquakes & and of the structure of the Earth by both natural and artificially generated seismic waves.






32. All unconsolidated materials above bedrock. Natural earthy materials on the Earth's surface & in places modified or even made by human activity & containing living matter & and supporting or capable of supporting plants out of doors.






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






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






35. The study of earthquakes & and of the structure of the Earth by both natural and artificially generated seismic waves.






36. A depression in the ground formed by the melting of a block of glacier ice buried or partially buried by drift.






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






38. Deserts in zones of descending air between 25 degrees and 30 degrees north and south latitude.






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






40. Any porous and permeable rock that yields oil or natural gas.






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






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






43. An area in which a large number of windmills have been erected to generate electrical power.






44. The process by which a binding & or cementing & agent is precipitated in spaces among individual particles of a deposit. Common cementing agents are calcite & quartz & and dolomite.






45. The principle that states the processes operating to change the Earth in the present also operated in the past.






46. A post of dripstone growing up from a cave floor.






47. A low & nearly flat accumulation of sediment deposited at the mouth of a river or stream & commonly triangular or fan-shaped.






48. A roughly circular reef with an occasional small & low & coral sand island surrounding a shallow lagoon.






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






50. The top of a wave.
