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. (Latin- Sol & Greek- Helios)the closest star to Earth. It is a giant ball of gas without any solid surface.






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






3. The theory of Plate Tectonics states that the Earth's crust is fragmented into a dozen or more large and small pieces floating on a semi-molten mantle.






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






5. A process of erosion in which wind carries off particles of dust and sand.






6. A method of sediment transport in which the turbulence of a fluid is able to keep particles supported in the fluid.






7. A group of stars that appear to make a pattern in the sky. The Big Dipper is a constellation.






8. To preserve & or to avoid wasteful use.






9. The line formed by the intersection of the axial plane of a fold with a bedding plane & marking where the bed shows its maximum curvature.






10. Extending across a continent.






11. Bent rock strata.






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






13. A thick layer of soil.






14. Any molten material that is extrusive or volcanic & or the rock that forms from a molten extrusive. Molten rock that flows at the Earth's surface.






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






16. Lacking in rainfall & very dry.






17. Water beneath the Earth's surface.






18. An individual grain or constituent of a rock.






19. The vertical distance between the crest and adjacent trough of a wave.






20. A large area of flat or nearly flat land.






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






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






23. A statement of relative age in layered rocks: In a series of sedimentary rocks that has not been overturned & the topmost layer is always the youngest and the bottommost layer is always the oldest.






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






25. The closest star to Earth besides the sun. It is approximately 4 light years away.






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






27. The line that separates one drainage basin from another.






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






29. The physical & chemical & and biological processes by which rock at or near the Earth's surface is broken down into smaller pieces.






30. The oldest eon in Earth history & extending from the origin of the Earth to about 3.9 billion years ago.






31. A device containing a free-swinging magnetic needle that is attracted to Earth's magnetic North Pole. Used to determine direction of travel.






32. To change back and forth uncertainly.






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






34. A mass of ice & formed by the recrystallization of snow & that flows forward & or has flowed at some time in the past.






35. Similar to a groin but built to keep sand out of a harbor entrance.






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






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






38. 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.






39. A measure of the strength of an earthquake based on the amount of movement recorded by a seismograph . compare Richter scale.






40. A waste material that contaminates air & water & or soil.






41. Formed when an organism is flattened (compressed) and a thin film of organic material from its body is left in the rock.






42. A floating ice sheet extending across water from a land-based glacier.






43. An icicle-shaped accumulation of dripstone hanging from cave roof.






44. Any place where bedrock is visible on the surface of the Earth.






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






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






47. A small & dust-bearing whirlwind.






48. A sedimentary rock composed primarily of biogenic sediments.






49. The acidity in rain due to gases from internal combustion engines and coal- and oil-burning power plants.






50. The galaxy where Earth is located.
