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. The stress is particularly severe in _________ - which are characterized by volcanism - metamorphism - deformation - and uplift






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






3. Forms over the Tropics and is warm






4. 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






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






6. 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






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






8. 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...






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






10. A major determiner of coastal climate






11. Weather occurs primarily due to density (temperature and moisture) differences between one location and another - These differences can occur due to the angle of the sun at any particular spot - which varies by latitude from the tropics






12. 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






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






14. Runoff and groundwater are stored as ________ in lakes






15. The best determiner of climate - as it is consistently and directly correlated with temperature - other factors: Rain shadows - as well as water currents - elevation and so forth






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






17. Two high waters and two low waters each day - in most locations - tides are semidiurnal






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






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






20. Formed by sodium chloride






21. Occur when two plates push together - Such faults are strong and relatively deep - Where the strongest earthquakes occur Example: mountain building in the Himalayas and the Andes






22. Divided into two main types: large - low- density gas giants and smaller - rocky terrestrials - There are at least 341 identified _______ - 8 of which are in the Solar System






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






24. Continental tropical (dry - warm air)






25. Traces of ancient life preserved in the strata as shells - footprints - and the like - Soft plant and animal tissues decompose quickly in the presence of decay bacteria - which exist wherever oxygen exists






26. The atmosphere is a __________ - and so small changes to one part of the system can grow to have large effects on the system as a whole - This makes it difficult to accurately predict weather more than a few days in advance






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






28. Oceans cover __ of the earth's surface






29. 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






30. The difference between levels of ocean water at high and low tides






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






32. One tidal cycle per day






33. Volcanoes are generally found where ________ are diverging or converging






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






35. The variety of ways by which water moves across the land - This includes both surface runoff and channel runoff - As it flows - the water may percolate into the ground - evaporate into the air - become stored in lakes or reservoirs - or be extracted






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






37. Texture is important in classifying ______ sedimentary rocks






38. The runoff produced by melting snow






39. Occurs at the instant when the sun's position in the sky is at its greatest angular distance on the other side of the equatorial plane from the observer's hemisphere - Depending on the shift of the calendar - the winter solstice occurs some time betw






40. Improved land - use practices can limit erosion by using techniques such as...






41. 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






42. Igneous rock that forms on the earth's surface - Examples obsidian - basalt - and pumice






43. Somewhat cooler disturbances in the photosphere






44. - 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






45. Maritime tropical (wet - warm air)






46. Distance to closest stars can be calculated by measuring the _________ - a slight shift in apparent position against the background of more distant stars as the earth travels around the sun






47. 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






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






49. 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






50. 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
