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 low spot between two successive waves.






2. A flood that rises and falls very rapidly.






3. An isolated & steep-sided & rocky mass or island just offshore from a rocky headland & usually on a shore platform.






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






5. 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.






6. A community of plants and/or animals and its physical environment & regarded as a unit.






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






8. A type of volcanic eruption characterized by nuees ardentes and the development of lava domes.






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






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






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






12. Where two plates are moving in opposite directions as in a mid-ocean ridge.






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






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






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






16. A region of high heat flow on the Earth's surface & thought to lie above a mantle plume .






17. The relationship between distances in the area being mapped and distances in the map itself.






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






19. The galaxy where Earth is located.






20. Open pit mining & typically for coal.






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






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






23. Evidence in rock of the presence of past life & such as a dinosaur bone & an ancient clam shell & or the footprint of a long-extinct animal as well as life history artifacts.






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






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






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






27. Verifying assessments made from satellite data by doing direct & 'on-the ground' measurements.






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






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






30. A thick layer of soil.






31. As applied to glacier ice & the process by which ice below the snow line is wasted by evaporation and melting.






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






33. The processes (mechanical and chemical) responsible for the wearing away & loosening & and dissolving of materials of the Earth's crust.






34. The amount of material a stream carries in suspension.






35. That part of the continental margin that lies between the continental shelf and the continental rise. Slope relatively steep & 3o - 6o. The continental slope is underlain by crustal rocks of the continent.






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






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






38. Containing moisture.






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






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






41. The geologic eon lying between the Archean and Phanerozoic eons & beginning about 2.5 billion years ago and ending about 0.57 billion years ago.






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






43. A thick layer of soil.






44. A building that contains one or more telescopes.






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






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






47. The green pigment in the cells of many plants that enables them to use sunlight to convert carbon dioxide and water into carbohydrates in the process called photosynthesis.






48. 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.






49. He area from which a stream and its tributaries receives its water.






50. Jupiter is named after the Roman king of the gods. It is the fifth planet from the Sun.
