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. Tends to move slowly and is replenished slowly - and so it can remain in aquifers for thousands of years






2. Large - scale movements of the earth's lithosphere - - The theory encompasses the older concepts of continental drift (first half of 20th century) and seafloor spreading (1960s)






3. Formed by sodium chloride






4. The science of the atmosphere and weather






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






6. Characterized by similar temperatures and moisture levels






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






8. Some isolated mountains were produced by volcanoes - including many apparently ________ that reach a great height above the ocean floor






9. 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






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






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






12. On maps - the characteristics of an air mass are represented by two letters: The lowercase letter represents ________ - and the uppercase letter represents temperature






13. When the moon is at first quarter or third quarter - the sun - earth and moon form a 90- degree (right) angle with the earth at the vertex - The combined effect of this alignment of the sun - earth - and moon results in tidal ranges on the earth - Wh






14. Form when magma or lava cools and solidifies - Depending on the rate of cooling - can contain visible crystals - while others can appear glassy






15. 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






16. One tidal cycle per day






17. 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...






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






19. The transformation of water vapor to liquid water droplets in the air - producing clouds and fog






20. Continental tropical (dry - warm air)






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






22. 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

23. Water transpired from plants and evaporated from the soil






24. 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






25. Forms over land and is associated with dry air






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






27. 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






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






29. 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.






30. Affected by factors such as weathering and impurities






31. Most sediments were deposited in beds that were originally horizontal - and any tilting is due to later earth movements






32. Occur when two plates pull away from each other - Such faults are generally weak and shallow Example: the Mid - Atlantic Range in the Atlantic Ocean






33. 1 hour of time






34. Form when dissolved mineral solutions crystalize out of lakes and oceans






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






36. 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






37. The degrees east or west of the prime meridian through Greenwich - England






38. Composed of the fragments of other types of rocks - Cover 75 to 80% of the earth's land area - Often deposited in distinct parallel layers - Weather and erosion break down other rock types into sediments - Over time - the sediments become cemented an






39. Water returns to the land surface at __________ than where it entered - under the force of gravity or gravity - induced pressures






40. Nearest galaxy - about 20 million light - years away






41. An opening - or rupture - in a planet's surface or crust - which allows hot molten rock - ash - and gases to escape from below the surface - Volcanic activity involving the extrusion of rock tends to form mountains or features like mountains over a p






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






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






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






45. 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






46. The Pacific Ring of Fire has examples of volcanoes caused by ___________ coming together






47. Igneous rock that cools beneath the earth's surface - Examples: plutons - dikes - and batholiths






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






49. Huge systems of stars - Milky Way is estimated to have 100 billion stars arranged in a great disk






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