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






2. Water that flows across watersheds during and immediately after severe rainstorms. In populated areas & stormwater runoff is often water that cannot be handled by existing sewer systems. Stormwater runoff is the leading source of water pollution in t






3. A narrow & elongate region in which one lithospheric plate descends relative to another.






4. The area immediately below the ground surface within which pore spaces are partially filled with water and partially filled with air.






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






6. A geometrical form taken by a mineral & giving external expression to orderly internal atomic arrangement.






7. The transformation of a soil from a solid to a liquid state as the result of increased pore pressure.






8. Any accumulation of material & by settling from water or air & chemical precipitation & evaporation from solution & etc.






9. A soft compact calcite & CaCO3 & with varying amounts of silica & quartz & feldspar & or other mineral impurities & generally gray-white or yellow-white and derived chiefly from fossil seashells.






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






11. A steep or vertical cliff & either above or below sea level.






12. An instrument that merely indicates the occurrence of an earthquake.






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






14. The area bordering a stream over which water spreads when the stream tops its channel banks.






15. The height of a place above sea level.






16. The vertical distance between the crest and adjacent trough of a wave.






17. 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.






18. 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.






19. Applies to igneous rocks that cool on the surface of the Earth & including beneath water; typically with small crystals due to the rapidity of cooling. Synonym of extrusive. Antonym of plutonic.






20. Deposits of wind-borne dust.






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






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






23. An imaginary circle around the earth that represents the halfway mark between the North and South Poles and establishes the boundary between the Northern and Southern Hemispheres.






24. 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.






25. The Earth's crust underlying the ocean basins which is formed at mid-oceanic ridges. It is typically 5 to 10 kilometers thick composed of basalt.






26. A natural depression in the surface of the land caused by the collapse of the roof of a cavern or subterranean passage & generally occurring in limestone regions.






27. A device containing a free-swinging magnetic needle that is attracted to Earth's magnetic North Pole. Used to determine direction of travel.






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






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






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






31. Enormous & thick sheets of rock that are part of the Earth's upper mantle that move and adjoin each other along zones of seismic activity. Many tectonic plates extend underneath both continents and sea floor.






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






33. Where two plates collide to form mountains.






34. The attractive force between two objects; its magnitude depends on their masses and the distance between them.






35. The effect of water and carbon dioxide absorbing outgoing infrared radiation & raising a system's temperature. The term is generally used with reference to the Earth's temperature & although it can also be applied to other systems & such as greenhous






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






37. One of several rock-forming minerals that contain at least 95% silica (quartz). and usually one or more other common elements.






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






39. 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.






40. A measure of acidity.






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






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






43. A permeable region of rock or soil through which ground water can move.






44. A hydrocarbon (coal or petroleum) that can be extracted from the Earth for use as a fuel. Fossil fuels are non-renewable energy sources.






45. The seaward edge of coast between low tide and effective wave action.






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






47. A hot & gaseous & self-luminous celestial body & as the Sun.






48. Pertaining to clastic material formed by volcanic explosion or aerial expulsion from a volcanic vent.






49. Mercury is named after the Roman messenger of the gods. It is the closest to the Sun.






50. The region of a shore that is covered at high tide and exposed at low tide.
