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. Continental tropical (dry - warm air)






3. A warm - water current that carries warm water from the Tropics to the Arctic regions of the North Atlantic Ocean - This accounts for higher temperatures and higher humidity on the Eastern Seaboard during the summer






4. Take up about 1/3 of the earth's land surface - many are formed by rain shadows - Usually have a large diurnal (day) and seasonal temperature range - with high daytime temperatures






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






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






7. The motive force behind land breezes and sea/lake breezes - also known as on - or off - shore winds - Land absorbs and radiates heat faster than water - but water releases heat over a longer period of time






8. Younger beds were originally deposited above older beds






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






10. The lateral movement of the plates is typically at speeds of ___ mm annually






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






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






13. Under solar conditions - gases are undergoing _____ to heavier elements with the increase of prodigious quantities of energy






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






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






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






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






18. Characterized by unusually warm ocean temperatures in the same area - Atlanta tropical cyclone activity is generally enhanced during La Nina - Often follows the El Nino - especially when the latter is strong






19. 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






20. The outermost part of the earth's interior is made up of two layers...






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






22. Result from the earth's axis being tilted to its orbital plane - NOT the result of the variation in the earth's distance to the sun (Because of its elliptical orbit - the earth as a whole is slightly warmer when away from the sun; this is because the






23. 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






24. Hotspot volcanoes are also found elsewhere in the Solar System - especially on...






25. Tides may be...






26. Travels in an orbit that is slightly elliptical (oval) - and so the distance from the sun ranges from 91.5 to 94.5 million miles - Its daily rotation deforms the earth to a flattened spheroid - with a polar radius slightly less than the equatorial ra






27. Sometimes called minor planets or planetoids - Bodies






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






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






30. Piled in waves and indicate rain or snow






31. 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






32. Maritime polar (wet - cold air)






33. Forms over land and is associated with dry air






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






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






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






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






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






39. Loose collections of ice - dust - and small rocky particles - measuring a few kilometers or tens of kilometers across






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






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






42. The degrees north or south of the equator






43. 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






44. 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...






45. 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






46. This upslope wind is called a...






47. Center: 3000

48. A ______________ - such as the Mid - Atlantic Ridge - has examples of volcanoes caused by divergent tectonic plates pulling apart






49. 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






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