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 area immediately below the ground surface within which pore spaces are partially filled with water and partially filled with air.






2. A volcanic mountain on the seafloor. If flat-topped & it is a guyot.






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






4. The amount of dissolved salt in water.






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






6. A zone in the Earth between 400 and 670 km below the surface separating the upper mantle from the lower mantle.






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






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






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






10. A building that contains one or more telescopes.






11. An earthquake that follows and has its epicenter near a larger earthquake.






12. The area bordering a stream over which water spreads when the stream tops its channel banks.






13. A soft compact calcite & CaCO3 & with varying amounts of silica & quartz & feldspar & or other mineral impurities & generally gray-white or yellow-white and derived chiefly from fossil seashells.






14. The innermost zone of Earth. It consists of two parts & an outer liquid section and an inner solid section & both chiefly of iron and nickel with about 10 percent lighter elements. It is surrounded by the mantle.






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






16. The color of a mineral in its powdered form obtained from scraping a sample on a ceramic plate






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






18. A hot & gaseous & self-luminous celestial body & as the Sun.






19. Plutonic. Antonym of extrusive. Pertaining to igneous rocks or features formed by the emplacement of magma in pre-existing rocks.






20. 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.






21. The weak or 'soft' zone in the upper mantle just below the lithosphere & involved in plate movement and isostatic adjustments. It lies 70 to 100 km below the surface and may extend to a depth of 400 km.






22. Surficial mining & in which the valuable rock is exposed by removal of overlying rock or soil.






23. A narrow & steep-walled depression in the ocean floor & much deeper than the adjacent ocean and associated with a subduction zone.






24. A measure of acidity.






25. The presence of layers in some rocks caused by parallel alignment of minerals.






26. The height of a place above sea level.






27. The effect of water and carbon dioxide absorbing outgoing infrared radiation & raising a system's temperature. The term is generally used with reference to the Earth's temperature & although it can also be applied to other systems & such as greenhous






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






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






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






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






32. Any accumulation of material & by settling from water or air & chemical precipitation & evaporation from solution & etc.






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






34. The attractive force between two objects; its magnitude depends on their masses and the distance between them.






35. 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.






36. The amount of dissolved salt in water.






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






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






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






40. The elevation at which snow persists throughout the year.






41. Molten rock & containing dissolved gases and suspended solid particles. At the Earth's surface & magma is known as lava.






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






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

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






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






46. The process of one plate descending beneath another.






47. Forms along a coast as wave erosion cuts through a headland.






48. The very slow & generally continuous downslope movement of soil and debris under the influence of gravity.






49. 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.






50. A naturally occurring inorganic solid that has a well-defined chemical composition and in which atoms are arranged in an ordered fashion.
