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. Both gravity and inertia work together to keep planets in orbit around the sun - Inertia makes a planet travel in a straight line






2. Two types of mountains are formed - depending on how the rock reacts to the tectonic forces






3. Seas - gulfs - bays - and other names






4. Takes approx. seven and a half earth months to revolve around the sun - Takes approx. eight earth months to rotate on its axis - a day on ________ is longer than a year






5. Oceans cover __ of the earth's surface






6. Piled in waves and indicate rain or snow






7. Generally forms deep in the mantle as one type of rock changes into another - Due to intense pressure - can show signs of bending and distortion - Examples: schist - marble - gneiss - and slate






8. There are approx. _____ days between each lunar cycle






9. Thought to originate in the Kuiper Belt - or associated scattered discs - which lie beyond the orbit of Neptune






10. Affected by factors such as weathering and impurities






11. 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






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






13. The strong temperature contrast between polar and tropical air gives rise to the ________






14. Large - dark clouds that indicate thunderstorms






15. 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...






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






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






18. The source of energy for evaporation is primarily through ___________






19. An individual weighing 200 lbs on Earth would weigh more on a _______________ - Weight is a function of gravity






20. Believed to originate at a much greater distance from the Sun - in a cloud (the Oort cloud) consisting of debris left over from the condensation of solar nebula - Comets are thrown from the outer planets or nearby stars - or as a result of collisions






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






22. A major determiner of coastal climate






23. 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.






24. Stars with the highest ___________ appear blue - while stars with the lowest surface temperature appear red






25. An area of frequent earthquakes and volcanic eruptions associated with the plate boundaries surrounding the Pacific Ocean - In a 40000 km horseshoe shape - associated with a nearly continuous series of oceanic trenches - volcanic arcs - and volcanic






26. Runoff and groundwater are stored as ________ in lakes






27. A huge ball of incandescent gases - Its mass is more than 300000 times that of the earth - Principal constituents are the lightest elements - hydrogen and helium






28. Refers to the long - term weather patterns of a large geographical area and takes into account temperature - humidity - and precipitation






29. The sun and oceans can also affect the weather of land - If the sun heats ocean waters for a period of time - water can evaporate - Once evaporated into the air - the moisture can spread over nearby land - thus making it cooler


30. Zero degrees latitude - generally has a tropical climate (warm and wet); at the extreme northern and southern latitudes (polar regions) - the climate is very cold and dry






31. Forms over water and is associated with wet air






32. A small Solar System body that orbits the Sun - When close enough to the sun - exhibits a visible coma (atmosphere) or a tail - both primarily from the effects of solar radiation upon the comet's nucleus - Have a variety of different orbital periods






33. The breakdown of rocks - soils and minerals through atmospheric chemicals or biologically produced chemicals (also known as biological weathering)






34. Seasons are marked by changes in the amount of sunlight - which in turn often cause cycles of dormancy in plants and hibernation in animals - These effects vary with latitude and with proximity to bodies of water






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






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






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






38. 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






39. The strength of gravity in our solar system depends on both the masses of the celestial objects and the _______ between them






40. The science of the atmosphere and weather






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

46. The movement (carrying away or displacement) of solids (sediment - soil - rock - and other particles) - usually by the agents of currents such as wind - water - or ice by downward or down - slope movement in response to gravity






47. The runoff produced by melting snow






48. Can influence climate by sending tremendous volumes of dust - ash - and smoke into the atmosphere






49. Less than 1% of the earth; this relatively thin zone (5 to 25 miles) contains the only rocks we can study - even in the deepest mines or drill holes






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