Earth Science

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. Mercury is named after the Roman messenger of the gods. It is the closest to the Sun.






2. Ratio between weight of given volume of material and weight of equal volume of pure water.






3. 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.






4. Deep steep-sided depression in the ocean floor caused by the subduction of oceanic crust beneath either other oceanic crust or continental crust.






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






6. Large area of extremely flat ocean floor lying near a continent and generally over 4 km in depth.






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






8. Synonym of intrusive. Antonym of volcanic. Applies to igneous rocks formed beneath the surface of the Earth; typically with large crystals due to the slowness of cooling.






9. Living in water.






10. The portion of the continental margin that lies between the abyssal plain and the continental slope. The continental rise is underlain by crustal rocks of the ocean basin.






11. A vent on the seafloor from which hydrothermal fluids are emitted. Upon mixing with seawater and cooling & the fluids precipitate a cloud of fine-grained sulfide minerals that resembles a cloud of black smoke.






12. The galaxy where Earth is located.






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






14. The seaward edge of coast between low tide and effective wave action.






15. The portion of the continental margin that lies between the abyssal plain and the continental slope. The continental rise is underlain by crustal rocks of the ocean basin.






16. A flat & dry plain covered with short grass.






17. An individual grain or constituent of a rock.






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






19. A supercontinent that existed from the the end of the Permian to the Jurassic & 300 to 200 million years ago & assembled from large continents like Euramerica & Gondwana & and Siberia & as well as smaller landmasses like the Cathaysian and Cimmerian






20. The surface between the zone of saturation and the zone of aeration.






21. The reflection of light on a given mineral's surface & classified by intensity and quality.






22. 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.






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






24. Deposits of wind-borne dust.






25. 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.






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






27. The rock beneath the soil.






28. 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.






29. Reduction of pore space between individual particles as the result of overlying sediments or of tectonic movements.






30. The resistance of a mineral to scratching & as measured by the Mohs scale.






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






32. The formation & advance and retreat of glaciers and the results of these activities.






33. 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.






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






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






36. The amount of dissolved salt in water.






37. Water beneath the Earth's surface.






38. Produced as a wave steepens and falls forward as the wave nears the shore.






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

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






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






42. 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.






43. Imaginary lines on a map or globe that measure distance in degrees north or south of the equator. Latitude lines extend horizontally & from east to west on a globe.






44. The sum of the processes that result in the wearing away or the progressive lowering of the Earth's surface by weathering & erosion & mass wasting & and transportation.






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






46. A major drainage divide separating the drainage to one ocean from another.






47. A seismic body wave that involves particle motion from side to side & perpendicular to the direction of wave propagation. S-waves are slower than P-waves and cannot travel through a liquid.






48. A portable time keeper with a mechanism for ensuring accuracy and adjusting itself & used for determining longitude at sea.






49. A natural depression in the surface of the land caused by the collapse of the roof of a cavern or subterranean passage & generally occurring in limestone regions.






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