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






2. The zones of seismic activity long which plates are in contact.






3. A small ice sheet.






4. A narrow strip of land along the margin of the ocean extending inland for a variable distance from low water mark.






5. An instrument that detects & magnifies & and records vibrations of the Earth & especially earthquakes.






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






7. A device built to study distant objects by making them appear closer.






8. In the geologic time scale a unit of time less than an era and greater than an epoch. Example: The Tertiary period was the earliest period in the Cenozoic era and included & among others & the Eocene epoch.






9. Sediments produced directly by the life processes of plants or animals.






10. 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






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






12. A narrow strip of land along the margin of the ocean extending inland for a variable distance from low water mark.






13. A coral reef attached directly to the mainland.






14. The current geologic era & which began 66.4 million years ago and continues to the present.






15. A building that contains one or more telescopes.






16. A delta formed at both sides of a tidal inlet.






17. A device built to study distant objects by making them appear closer.






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






19. A sedimentary rock composed primarily of biogenic sediments.






20. A coral reef separated from the mainland by a lagoon.






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






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






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






24. The sudden fall of one or more large pieces of a rock from a cliff.






25. 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.






26. A person who makes maps.






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






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






29. The tectonic region in which two plates meet.






30. A valley carved by glacier erosion and whose cross-valley profile has steep sides and a nearly flat floor & suggestive of a large letter 'you'.






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






32. Containing moisture.






33. The process by which building stone & usually in blocks or sheets & is extracted from the Earth. radiation -- (Electromagnetic radiation) -- energy that travels through space in the form of waves without the intervention of matter & as in the transp






34. A mound or ridge of sediment deposited by a glacier.






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






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






37. A vertical conduit through the Earth's crust below a volcano & through Which magma has passed.






38. 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.






39. A thick layer of soil.






40. A valley caused by extension of the Earth's crust. Its floor forms as a portion of the crust moves downward along normal faults.






41. Gases (primarily water and carbon dioxide & but also a variety of sulfur and nitrogen compounds and gaseous hydrocarbons) that trap the Sun's heat in the atmosphere.






42. A planetary satellite.






43. 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.






44. All of space and everything in it.






45. A giant structure that contains hundreds of billions of stars.






46. The process of removing metal from ore.






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






48. A type of thermal spring which ejects water intermittently with considerable force.






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






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