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






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. Generally forms deep in the mantle as one type of rock changes into another - Due to intense pressure - can show signs of bending and distortion - Examples: schist - marble - gneiss - and slate






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






5. The farther from the tropics you are positioned - the ________ the angle of the sun - This causes those locations to be cooler due to the indirect sunlight






6. Human civilization has lasted only _____ years






7. 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






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






9. Bbreaking along flat surfaces

11. Faulting and folding






12. Water transpired from plants and evaporated from the soil






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






14. Around a new or full moon - when the sun - moon - and the earth form a line - the tidal forces due to the sun reinforce those of the moon - The tide's range is at a maximum and is called a spring tide (spring as in 'to jump/leap -' not the season)






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






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






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






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






19. Deviates by an angle of approximately 23.5 degrees - Thus - at any given time during summer or winter - one part of the planet is more directly exposed to the rays of the sun - This exposure alternates as the earth revolves in its orbit

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






22. Evaporation often implicitly includes ___________ from plants - although together they are specifically referred to as evapotranspiration






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






24. Continental tropical (dry - warm air)






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






26. Continental polar (dry - cold air)






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






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






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






30. After the moon has waxed through crescent - quarter - and gibbous phases - a ________ appears - At that time - the moon rises at sunset - and we see all of its illuminated side - Then the phase wanes gradually to another new moon






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

32. 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






33. The fossiliferous strata record is only the last __% of the earth's history






34. The cold - water current that flows north to south off the _____________ keeps the West Coast fairly cool during the summer - Cold - water currents create cooler temperatures in areas that would otherwise be much warmer






35. Texture is important in classifying ______ sedimentary rocks






36. Believed to originate at a much greater distance from the Sun - in a cloud (the Oort cloud) consisting of debris left over from the condensation of solar nebula - Comets are thrown from the outer planets or nearby stars - or as a result of collisions






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






38. Sedimentary rocks containing large fragments of other rock material - e.g. Sandstone






39. 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






40. 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






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






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

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






49. 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
