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






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






3. The rigid outer shell of the Earth. It includes the crust and uppermost mantle and is on the order of 100 km in thickness.






4. 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.






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






6. A planetary satellite.






7. A fracture or zone of fractures along the boundaries of tectonic plates where movement has taken place.






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






9. A spring whose temperature is 6.5o C or more above mean annual air temperature.






10. Lies half way between the north and south magnetic poles.






11. An abandoned meander .






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






13. A continuous well-defined mass of material of sufficient ore content to make extraction economically feasible. compare mineral deposit.






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






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






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






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






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






19. The generally dark & more or less stable part of the organic matter in a soil & so well decomposed that the original sources cannot be identified.






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






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






22. (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.






23. The internal resistance to flow in a liquid.






24. The formation & advance and retreat of glaciers and the results of these activities.






25. The areas of & in & or constituting a city.






26. An atmospheric shield providing the Earth with protection from ultra-violet rays which can cause sun burn & skin cancer and the destruction of the delicate plant life which supports the planet's food chain.






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






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






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






30. The areas of & in & or constituting a city.






31. A small & dust-bearing whirlwind.






32. Living in water.






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






34. 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.






35. A building that contains one or more telescopes.






36. An atmospheric shield providing the Earth with protection from ultra-violet rays which can cause sun burn & skin cancer and the destruction of the delicate plant life which supports the planet's food chain.






37. A process by which salts accumulate in soil.






38. A collection of maps.






39. Shapes & like mountains or hills that make up the Earth's surface.






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






41. A pillar formed as a stalactite and stalagmite meet.






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






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






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






45. The uprush of a wave onto the beach followed by the return flow of the water down the beach slope in the intervals between waves.






46. 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.






47. The height of a place above sea level.






48. 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.






49. A study designed to collect critical data to be used for comparison or as a control in a later study.






50. 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.
