CSET Earth

Subjects : cset, 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. Test the item against materials of known hardness; for example - use your fingernail or the graphite in a pencil to attempt to scratch the items. This process should result in assigning a relative hardness to the unknown items.






2. Largest zone of the planet (68%); crystalline silicates - rich in magnesium - calcium - and iron; very hot and mainly solid - but local melting to magma is the source of volcanic eruptions






3. Occur when two plates slip past each other - Such faults are generally moderate and are relatively shallow Example: The San Andreas Fault






4. The resulting dust layer would act as a shield - blocking out much of the sun's rays - This would result in lower global temperatures and a general _____ of the earth






5. Characterized by similar temperatures and moisture levels






6. Sun heats water in the oceans - Water evaporates as vapor into the air - Ice and snow can sublimate directly into water vapor...- Over time - the water reenters the ocean - where the water cycle started






7. At any given time - regardless of season - the Northern and Southern Hemispheres experience...






8. Spiral - elliptical - and irregular form are speckled throughout the visible universe - Largest telescope has detected galaxies to its limit of several billion light - years






9. Paleontology: Fossil evidence indicates the similarity of fossils on both sides of the Atlantic Ocean - Continental 'jigsaw puzzle': The outlines of the continents seem to fit together






10. Runoff and groundwater are stored as ________ in lakes






11. The science of the atmosphere and weather






12. Featherlike clouds that indicate fair weather






13. Ancient astronomers found that eclipses occurred periodically and learned to predict them accurately - Lunar and solar






14. Maritime polar (wet - cold air)






15. Forms over the Tropics and is warm






16. The major mountains tend to occur in __________ - indicating tectonic plate boundaries and activity






17. Method of using the present to interpret the past - Processes occurring today are observed carefully and their effects are measured - Then - geologists assume that similar effects in ancient rocks were caused by processes similar to those of the pres






18. The process of chemical or physical breakdown of earth rocks - soils - and their minerals






19. The evaporation of these oceans is how we get most of our __________ - and their temperature determines our climate and wind patterns






20. The process in which one type of rock changes into another






21. The science that describes and interprets the earth Fields: - Geomorphology (land forms) - Petrology (rocks) - Stratigraphy (layered rocks) - Paleontology (fossils)






22. Two feldspars (orthoclase and plagioclase) - quartz - olivine - and augite - These five minerals are silicates - built from interlocking silicon and oxygen atoms






23. Some infiltration stays close to the land surface and can seep back into surface - water bodies (and the ocean) as...






24. Volcanoes are also found in __________ - where the denser oceanic plates are forced under continental plates; this adds massive volumes of water to the mantle - allowing magma to melt more readily and rise to the surface to form volcanoes






25. Almost all familiar weather phenomena occur in the __________ (the lower part of the atmosphere)






26. The transformation of water from liquid to gas phases as it moves from the ground or bodies of water into the overlying atmosphere






27. Comprises one global - interconnected body of salt water often (though generally recognized as several separate oceans) - A continuous body of water with relatively free interchange among its parts






28. (or summer time zones) include an offset (typically +1 hour) for daylight saving time






29. Solar Atmosphere is divided into the inner chromosphere with explosive prominences and the outer corona - a glowing halo visible only during a total eclipse - Constantly emitting particles as a...






30. Cause pressure differences - A hot surface heats the air above it and the air expands - lowering the air pressure and its density






31. Some precipitation falls as ____ and can accumulate as ice caps and glaciers - which can store water for thousands of years






32. Tides may be...






33. - The materials left over after the rock breaks down combine with organic material - The mineral content is determined by the parent material; thus - a soil derived from a single rock type can often be deficient in one or more minerals for good ferti






34. Evaporation often implicitly includes ___________ from plants - although together they are specifically referred to as evapotranspiration






35. Giant masses of solid rock that float upon the earth's mantle - These plates move in relation to one another at one of three types of plate boundaries...






36. Smooth layers of low clouds that indicate a chance of drizzle or snow






37. The tidal force produced by the sun is ____ as large as that produced by the moon






38. The rising of the earth's ocean surface caused by the tidal forces of the moon and the sun acting on the oceans






39. Officially defined as sustained sea surface temperature anomalies of magnitude greater than 0.5






40. Classified as warm - water or cold - water currents






41. Different visual appearance; when discovered - comets show a perceptible coma while asteroids do not






42. Pulls the planets toward the sun - while their inertia keeps them moving forward in an elliptical orbit around the sun

43. Sedimentary rocks containing large fragments of other rock material - e.g. Sandstone






44. Earth movements - The result of forces within the earth - where temperature and pressure differences lead to instability






45. Rocks are placed into groups according to how they form...






46. Forms over land and is associated with dry air






47. The layers of sediment deposited in a quiet environment - Common sites of deposition are lakes - deltas at the mouths of rivers - beaches and sandbars along the coast - and (most important) the marine environment






48. Travels around the earth each month - - Distance from the earth averages 237000 miles - Has rugged topography formed billions of years ago by volcanic eruptions and meteorite impacts - Mass is 1/6th that of Earth






49. Occurs when the moon sets at sunset - Then the moon is between the earth and the sun - so we see only the dark half of the moon
