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






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






3. 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.






4. The surface between the zone of saturation and the zone of aeration.






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






6. 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.






7. The principle that states the processes operating to change the Earth in the present also operated in the past.






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






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






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






11. The speed at which water flows.






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






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






14. 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






15. The naturally occurring material from which a mineral or minerals of economic value can be extracted at a profit.






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






17. A lake of lava & usually basaltic & in a volcanic caldera.






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






19. 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.






20. A segment of an active fault zone that has not experienced a major earthquake during a time period when most other segments of the zone have. They are generally regarded as having a higher potential for future earthquakes.






21. A delta formed at both sides of a tidal inlet.






22. A deposit of partly decayed plant remains in a very wet environment; marsh or swamp deposit of plant remains containing more than 50 percent carbon.






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






24. The rise and fall of sea level caused by the gravitational pull of the Sun and Moon on the Earth.






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






26. Produced as a wave steepens and falls forward as the wave nears the shore.






27. The zones of seismic activity long which plates are in contact.






28. Heat transport by direct transfer of energy from one particle to another & without moving the particle to a new location.






29. Living in water.






30. Woodland that usually gets at least 100 inches of rain each year.






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






32. An abandoned meander .






33. A small & dust-bearing whirlwind.






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






35. A measure of the size of an earthquake in terms of the damage it causes.






36. 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.






37. The initial point within the Earth that ruptures in an earthquake & directly below the epicenter. The point within the Earth which is the center of an earthquake & at which strain energy is first released and converted to elastic wave energy.






38. An ingredient in a food or other substance that nourishes or promotes growth.






39. Any of various minerals prized for beauty & durability & and rarity. A few noncrystalline materials of organic origin (e.g. & pearl & red coral & and amber) also are classified as gemstones.






40. The theory of Plate Tectonics states that the Earth's crust is fragmented into a dozen or more large and small pieces floating on a semi-molten mantle.






41. 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






42. A sedimentary rock made up of chemical sediments. Example: rock salt.






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






44. (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.






45. The surface between the zone of saturation and the zone of aeration.






46. The method of locating an epicenter by determining how far it lies from three widely separated seismographs.






47. Glacial drift composed of rock fragments that range from clay to boulder size and randomly arranged without bedding.






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






49. The upper horizons in a soil & through which gravitational moisture travels & removing soluble decomposition products.






50. A volcano in the shape of a flattened cone & broad and low & built by very fluid flows of basaltic lava.
