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. (Greek-Aphrodite)named after the Roman goddess of love. It is the planet closest in size to Earth and the second planted from the Sun.






2. 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.






3. A rigid segment of the Earth's lithosphere that moves horizontally and adjoins other plates along zones of seismic activity. Plates may include portions of both continents and ocean basins.






4. Any molten material that is extrusive or volcanic & or the rock that forms from a molten extrusive. Molten rock that flows at the Earth's surface.






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






6. A waste material that contaminates air & water & or soil.






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






8. The Sun with all the celestial bodies that revolve around it.






9. A group of stars that appear to make a pattern in the sky. The Big Dipper is a constellation.






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






11. 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.






12. Containing moisture.






13. The average weather conditions of an area over many years & as measured by temperature & wind speed & and precipitation.






14. Objects revolving around the sun that are too small and too numerous to be considered planets.






15. A large ridge or mound-like structure within a body of water that is built by calcareous organisms such as corals & red algae & and bivalves.






16. 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.






17. A large area of flat or nearly flat land.






18. A sea wave produced by any large-scale & short duration disturbance on the seafloor & commonly a shallow submarine earthquake but possibly also a submarine slide or volcanic eruption.






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






20. Geologic time expressed in years before the present.






21. The dust-sized & sharp-edged & glassy particles resulting from an explosive volcanic eruption.






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






23. 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






24. Any seismic wave that travels through the body of Earth & rather than along its surface.






25. 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.






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






27. A detailed mathematical description of the cause-and-effect relationships between events that can be used to predict or explain other such events.






28. A lake in an abandoned meander.






29. The reflection of light on a given mineral's surface & classified by intensity and quality.






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






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






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






33. Refers to rock or sediments made up primarily of broken fragments of pre-existing rocks or minerals.






34. 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.






35. A process by which salts accumulate in soil.






36. Lava extruded beneath water characterized by pillow shapes.






37. A term applied to large areas of basaltic lava presumably extruded from fissures.






38. A method of sediment transport in which the turbulence of a fluid is able to keep particles supported in the fluid.






39. A mass of ice & formed by the recrystallization of snow & that flows forward & or has flowed at some time in the past.






40. The speed at which water flows.






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






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






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






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






45. An area subject to dust storms & especially south central United States .






46. Scratches & or small channels & gouged by glacier action. Occur on boulders & pebbles & and bedrock. Striations along bedrock indicate direction of ice movement.






47. Bent rock strata.






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






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






50. All unconsolidated materials above bedrock. Natural earthy materials on the Earth's surface & in places modified or even made by human activity & containing living matter & and supporting or capable of supporting plants out of doors.
