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. Bbreaking along flat surfaces






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






3. The result of the buildup of once - living things






4. The spectra of distant objects display a red shift - which is interpreted as meaning that they are rapidly receding from us - This apparent expansion of the universe has given rise to the big bang theory of cosmology - in which one primeval mass expl






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






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






7. Erosion in many places is increased by human land use - Poor land - use practices include deforestation - overgrazing - unmanaged construction activity - and road building






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






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






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






11. Formed by sodium chloride






12. 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






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






14. The North Pole is in the Arctic Ocean - and thus its temperature extremes are buffered by the water - The result is that the South Pole is consistently _______ during the southern winter than the North Pole during the northern winter






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






16. Cirrus - Stratus - Cumulonimbus - Altostratus






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






18. 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






19. 4 terrestrials: Mercury - Venus - Mars - Earth 4 gas giants: Jupiter - Saturn - Uranus - Neptune At least 5 dwarf planets: Ceres - Pluto - Makemake - Haumea - Eris






20. Tides may be...






21. 1 hour of time






22. Comprised of the crust and the rigid uppermost part of the mantle - broken up into tectonic plates (7 major and many minor) - ride on the asthenosphere






23. 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...






24. Oceans cover __ of the earth's surface






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






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






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. Mountains blocking the path of precipitation to the desert






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






30. The tendency of a moving object to stay in a straight line or a stationary object to remain in place - Without _______ - a planet would be pulled into the sun






31. 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






32. Faulting and folding






33. 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






34. 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






35. Center: 3000

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






37. Runoff and groundwater are stored as ________ in lakes






38. 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






39. 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






40. 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

41. Can thaw and melt - and the ensuing water flows overland as snowmelt






42. Scientists theorize that massive volcanic eruptions on a global scale contributed to the earth's cooling - resulting in the onset of the...






43. Not all runoff flows into rivers; much of it infiltrates into the ground through...






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






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






46. A continuous drill would find gas - oil - and water in that order - The three substances occur in their order of density - with the lightest substance on top and the heaviest on the bottom






47. 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






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