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. A chuck of rock or dust in space.






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






3. A stone or boulder & glacially transported from place of origin and left in an area of different bedrock composition.






4. A famous scientist who proposed that the Sun was the center of the solar system not the Earth. (Heliocentrism)






5. Temporary accumulations of sediments that collect between low and high water marks.






6. A wall built out from the shore & usually at perpendicular to it to trap sand carried by longshore currents .






7. In a stream & the volume of water passing through a channel in a given time.






8. Imaginary lines on a map or globe that measure distance in degrees east or west of the prime meridian. Longitude lines extend vertically & from pole to pole on a globe.






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






10. A study designed to collect critical data to be used for comparison or as a control in a later study.






11. The direction & north (normal) or south (reversed) & that a magnetic compass needle points.






12. 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.






13. Fossils formed when water containing minerals leaks into a mold. The minerals harden to form a copy of the original structure or organism.






14. An eruption of lava that takes place from a fracture & usually without producing a cone.






15. A layer of sedimentary rock; plural is strata.






16. The two days of the year on which neither hemisphere is tilted toward or away from the sun.






17. A fracture or zone of fractures along the boundaries of tectonic plates where movement has taken place.






18. A conical volcano formed by the accumulation of pyroclastic debris around a vent.






19. A planetary satellite.






20. Heat extracted from the Earth for use as an power source.






21. The solid innermost part of the core with a diameter of a little over 1 &200 km.






22. An eon of geologic time extending from about 3.9 billion years to 2.5 billion years ago.






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






24. 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.






25. 1. A low & bowl-shaped area of land surrounded by higher lands. 2. any large depression in which sediments are deposited.






26. Containing moisture.






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






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






29. 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.






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






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






32. Heat extracted from the Earth for use as an power source.






33. Flat land covered with tall grass and wildflowers.






34. An era of time during the Phanerozoic eon lasting from 245 million years ago to 66.4 million ago.






35. A blanket of wind-driven sand with an upper surface about a meter above ground level.






36. Turbulent stream water flow down a steep gradient & but not as steep as in a waterfall.






37. Uranus is named after the Roman god of the sky. It is the seventh planet from the Sun.






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






39. Highly mafic igneous volcanic rock & typically fine-grained and dark in color; rough volcanic equivalent of gabbro. Basalt is the most abundant volcanic rock in the Earth's crust.






40. Materials that are found in nature that are useful or necessary for people to live.






41. A system that uses a constellation of 24 satellites & their ground stations & and individual GPS receivers to accurately locate points on Earth.






42. 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.






43. The part of the crust that directly underlies the continents and continental shelves. Averages about 35 km in thickness & but may be over 70 km thick under largest mountain ranges.






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






45. The first scientist to make systematic use of the telescope in looking at the heavens.






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






47. 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.






48. The pattern of water circulation from the ocean to the atmosphere to the land and back to the ocean.






49. An area where fresh water comes into contact with seawater & usually in a partly enclosed coastal body of water; a mix of fresh and salt water where the current of a stream meets the tides.






50. 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.
