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. 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






2. 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






3. 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






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






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






6. Bbreaking along flat surfaces






7. Affected by factors such as weathering and impurities






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






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






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






11. A semi - closed coastal body of water with one or more rivers or streams flowing into it - and with a free connection to the open sea - Often associated with high levels of biological diversity - They are made up of brackish water - Often given names






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






13. Some groundwater finds openings in the land surface and emerges as...






14. Theory that the earth's continents were originally united as a supercontinent - Pangaea - Established by Alfred Wegener in the early 1900s






15. The movement of rainwater as it filters through soil and rocks into the ground - becoming groundwater






16. 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






17. 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






18. 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






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






20. 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






21. Featherlike clouds that indicate fair weather






22. Faulting and folding






23. Temperature - pressure - and composition






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






25. 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






26. 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






27. Forms over land and is associated with dry air






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






29. 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






30. (in descending order of size) the Pacific Ocean - the Atlantic Ocean - the Indian Ocean - the Southern Ocean and the Arctic Ocean






31. Human civilization has lasted only _____ years






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






33. The center of the sun may have a temperature of millions of degrees; the visible surface - the ______ - is about 6000






34. A major determiner of coastal climate






35. Maritime polar (wet - cold air)






36. 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






37. A natural flow of water - usually freshwater - traveling toward an ocean - a lake - or another stream






38. Volcanoes can also form where there is stretching and thinning of the...

41. 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






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






43. 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
