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. Where two plates collide to form mountains.






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






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






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






5. The layer of gases (air) & that surrounds a planet or moon.






6. To preserve & or to avoid wasteful use.






7. The height of a place above sea level.






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






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






10. An accumulation of wind driven sand into a distinctive shape.






11. Deep steep-sided depression in the ocean floor caused by the subduction of oceanic crust beneath either other oceanic crust or continental crust.






12. The reserves of a valuable mineral commodity plus all other mineral deposits that may eventually become available & even those that are presumed to exist but have not yet been discovered and those that are not economically or technologically exploita






13. The remains of an extremely massive star pulled into a small volume by the force of gravity.






14. The chronological sequence of units of Earth time.






15. An instrument used to measure the speed of wind.






16. The precipitation that runs directly off the surface to stream or body of standing water.






17. 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.






18. 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.






19. A volcanic mountain on the seafloor. If flat-topped & it is a guyot.






20. Lacking in rainfall & very dry.






21. Where one plate slides beneath another plate as the two are pushed together & a subduction zone.






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






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






24. The condition of equilibrium & comparable to floating & of units of the lithosphere above the asthenosphere.






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






26. 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.






27. The concept of a sequence of events involving the formation & alteration & destruction and reformation of rocks as a result of geologic processes.






28. 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






29. The most recent eon of geologic time beginning 570 million years ago and continuing to the present.






30. Extending across a continent.






31. A dense & hot (sometimes incandescent) cloud of volcanic ash and gas produced in a Pelean eruption.






32. Deposition of fine mineral particles (silt) on the beds of streams or lakes.






33. A naturally occurring inorganic solid that has a well-defined chemical composition and in which atoms are arranged in an ordered fashion.






34. The processes of weathering by which physical actions such as frost wedging break down a rock into fragments & involving no chemical change.






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






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






37. The presence of layers in some rocks caused by parallel alignment of minerals.






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






39. A coral reef attached directly to the mainland.






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






41. The very small particles of dirt & soot & and other pollutants that are present in the air.






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






43. Extending across a continent.






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






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






46. A molecule composed of three atoms of oxygen and mostly found in the stratosphere. Though beneficial in the upper atmosphere & at ground level & ozone is called photochemical smog & and is a respiratory irritant and considered a pollutant.






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






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






49. A supercontinent that existed from the Jurassic to Early Tertiary after splitting from Pangea; composed of Laurentia & Baltica & Avalonia & (modern North America & Scandinavia & Greenland & Western and Central Europe); eventually fragmented into Eur
