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






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






3. The prediction that climate will warm as a result of the addition to the atmosphere of humanly produced greenhouse gases.






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






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






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






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






8. The rigid outer shell of the Earth. It includes the crust and uppermost mantle and is on the order of 100 km in thickness.






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






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






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






12. The process of mountain building.






13. 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.






14. 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






15. A hole or basin cut into bedrock of a stream by the abrasive action of pebbles and sand swirled by turbulent stream flow.






16. Gases that can be dissociated by solar radiation & which releases chlorine & which in turn destroys ozone.

17. The upper horizons in a soil & through which gravitational moisture travels & removing soluble decomposition products.






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






19. The level of light that penetrates through water.






20. The persistence of wind-formed waves after wind ceases.






21. An area of land that delivers runoff water & sediment & and dissolved substances to surface water bodies & such as rivers or lakes. All watersheds consist of boundaries & a basin and collection areas.






22. 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.






23. 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.






24. A wall built out from the shore & usually at perpendicular to it to trap sand carried by longshore currents .






25. A layer of sedimentary rock; plural is strata.






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






27. A vent in the surface of the Earth & from which lava & ash & and gases erupt.






28. Refers to rock or sediments made up primarily of broken fragments of pre-existing rocks or minerals.






29. A rigid segment of the Earth's lithosphere that moves horizontally and adjoins other plates along zones of seismic activity. Plates may include portions of both continents and ocean basins.






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






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






32. A flood that rises and falls very rapidly.






33. 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.






34. Named after the Roman god of the sea. It is the eighth planet from the Sun.






35. The process by which ocean floors spread laterally from crests of main ocean ridges. As material moves laterally from the ridge & new material replaces it along the ridge crest by welling upward from the mantle.






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






37. The accumulation of material in layers or beds.






38. The point on the Earth's surface directly above the focus of an earthquake.






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






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






41. Turbulent stream water flow down a steep gradient & but not as steep as in a waterfall.






42. 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.






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






44. The symbol used on a map to indicate directions & both cardinal and ordinal.






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






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






47. The most recent eon of geologic time beginning 570 million years ago and continuing to the present.






48. The process by which an unconsolidated deposit of sediments is converted in to solid rock.






49. A slide involving a downward and usually sudden movement of newly detached segments of bedrock sliding or slipping over an inclined surface of weakness such as a bedding plane & fault plane & or joint surface.






50. A flood that rises and falls very rapidly.
