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. 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.






2. Flat land covered with tall grass and wildflowers.






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






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






5. A plate boundary in which plates on opposite sides of the boundary move past each other in opposite directions. The San Andreas fault of California is a good example.






6. A sedimentary rock composed of combustible matter derived from the partial decomposition of plant material.






7. Pertaining to or composed of granite & a coarse-grained igneous rock dominated by light-colored minerals & consisting of about 50 percent orthoclase & 25 percent quartz & and balance of feldspars and ferromagnesian silicates. Granite is commonly foun






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






9. A protective wall built offshore and usually parallel to the shore.






10. 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.






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






12. A reverse fault on which the dip angle of the fault plane is 15 degrees or less.






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






14. A guide to reading a map that typically contains distance scales & arrows indicating direction & and/or explanations of symbols used.






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






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






17. (Latin- Terra & Greek- Gaia) Earth is named after the ancient Germanic Goddess of the soil. It is the third planet from the Sun.






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






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






20. Bent rock strata.






21. The level of light that penetrates through water.






22. 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.






23. An aggregate of one or more minerals in varying proportions.






24. Living parts of the environment that can renew or replace themselves.






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






26. A large & basin-shaped volcanic depression & more or less circular in form. Typically steep-sided & found at the summit of a shield volcano.






27. Rock formed from the accumulation of sediment & Which may consist of fragments and mineral grains of varying sizes from pre-existing rocks & remains or products of animals and plants & the products of chemical action & or mixtures of these.






28. A cavity in a lava & formed by the entrapment of a gas bubble during solidification of the lava.






29. The science that deals with the study of the planet Earth--the materials of which it is made & the processes that act to change these materials from one form to another & and the history recorded by these materials; the forces acting to deform the ou






30. 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.






31. A general term for a relatively hard layer of soil at or just below the ground surface & cemented by silica & iron oxide & calcium carbonate & or organic matter.






32. A sea level change due to change in load on Earth's crust.






33. The straightening and/or deepening of a river channel.






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






35. A steep-sided rounded extrusion of highly viscous lava squeezed out from a volcano and forming a dome-shaped or bulbous mass above and around the volcanic vent. The structure generally develops inside a volcanic crater.






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






37. 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.






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






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






40. A volcano that is composed of alternating layers of lava and pyroclastic material & along with abundant dikes and sills. Viscous & intermediate lava may flow from a central vent. Example: Mt. Fuji in Japan.






41. The point on the Earth's surface that is directly above the focus of an earthquake.






42. The point on the Earth's surface where a magnetic needle points vertically downward (north magnetic pole) or vertically upward (south magnetic pole).






43. The outermost layer of the Earth & varying in thickness from about 10 kilometers (6 miles) below the oceans & to 65 kilometers (about 40 miles) below the continents; represents less than 1 percent of the Earth's volume.






44. A process by which salts accumulate in soil.






45. A worldwide change in sea level & such as caused by melting glaciers.






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






47. The galaxy where Earth is located.






48. A lake in an abandoned meander.






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






50. A natural open space underground & large enough for a person to enter. Most commonly occur by the dissolution of soluble rocks & generally limestone.
