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






2. A mound or ridge of sediment deposited by a glacier.






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






4. A stone or boulder & glacially transported from place of origin and left in an area of different bedrock composition.






5. Soil conditions prevailing in area whose mean annual temperature is 0o C.






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






7. 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






8. The pattern of water circulation from the ocean to the atmosphere to the land and back to the ocean.






9. Pluto is named after the Roman god of the Underworld. No longer considered a planet.






10. A tool for measuring the relative clarity of water.






11. 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.






12. The point on the Earth's surface directly above the focus of an earthquake.






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






14. The level of light that penetrates through water.






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






16. A conical volcano formed by the accumulation of pyroclastic debris around a vent.






17. A region of high heat flow on the Earth's surface & thought to lie above a mantle plume .






18. Deserts formed by blocking moisture-bearing winds with mountain barriers.






19. A ridge of high water associated with a hurricane and which floods over the shore .






20. A river that is able to maintain its flow through a desert because of water received from outside the desert.






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






22. A valley carved by glacier erosion and whose cross-valley profile has steep sides and a nearly flat floor & suggestive of a large letter 'you'.






23. Ratio between weight of given volume of material and weight of equal volume of pure water.






24. Swamp that forms in the low lying flood plain behind a levee.






25. The production of living matter by organisms that make food using sunlight or chemicals. Usually expressed as grams of carbon per square meter per year.






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






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






28. 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






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






30. That portion of the Earth below the crust and reaching to about 2 &780 km & where a transition zone of about 100 km thickness separates it from the core.






31. To change back and forth uncertainly.






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






33. 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.






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






35. 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.






36. 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.






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






38. Gases that can be dissociated by solar radiation & which releases chlorine & which in turn destroys ozone.

40. 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.






41. 1. A low & bowl-shaped area of land surrounded by higher lands. 2. any large depression in which sediments are deposited.






42. A supercontinent that existed from the the end of the Permian to the Jurassic & 300 to 200 million years ago & assembled from large continents like Euramerica & Gondwana & and Siberia & as well as smaller landmasses like the Cathaysian and Cimmerian

46. 1. A mass of sand & gravel & or alluvium deposited on the bed of a stream & sea & or lake & or at the mouth of a stream 2. A unit of pressure & approximately equal to atmospheric pressure at sea level.






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






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