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






2. Maritime polar (wet - cold air)






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






4. Defined by geometrically subdividing the earth's spheroid into 24 lunes (wedge - shaped sections) - bordered by meridians - each 15






5. 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






6. Continental tropical (dry - warm air)






7. Rising air currents take the vapor up into the atmopshere where cooler temperatures cause it to condense into ____






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






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






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






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






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

13. Some infiltration stays close to the land surface and can seep back into surface - water bodies (and the ocean) as...






14. Younger beds were originally deposited above older beds






15. Natural chemical compounds that are the crystals that make up rocks - Each has a specific composition or narrow range of composition






16. This scale assigns a fixed number to 10 reference materials. Talc (1) is the softest and diamond (10) is the hardest

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






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






19. 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






20. 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






21. Cirrus - Stratus - Cumulonimbus - Altostratus






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






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






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






25. Continental polar (dry - cold air)






26. 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






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






28. Formed by sodium chloride






29. A land form that stretches above the surrounding land in a limited area - with a peak - Usually produced by the movement of lithospheric plates






30. Can influence climate by sending tremendous volumes of dust - ash - and smoke into the atmosphere






31. Forms over land and is associated with dry air






32. 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






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






34. 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)






35. Most sediments were deposited in beds that were originally horizontal - and any tilting is due to later earth movements






36. Form when dissolved mineral solutions crystalize out of lakes and oceans






37. One tidal cycle per day






38. Darkens the moon as the earth passes between it and the sun - casting a shadow on the moon - may be seen from anywhere the moon is visible - about half of the earth






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






40. Formed from calcium carbonate - also an example of chemical sedimentary rocks - like roock salt - can contain organic or once - living matter and can record the history of that matter's formation in features such as strata - fossil evidence - and rip






41. The degrees east or west of the prime meridian through Greenwich - England






42. 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






43. 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






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






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






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






47. Condensed water vapor that falls to the earth's surface - Most precipitation occurs as rain - but also includes snow - hail - fog drip - graupel - and sleet






48. Pulls the planets toward the sun - while their inertia keeps them moving forward in an elliptical orbit around the sun

49. 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






50. Air currents move clouds around the globe and cloud particles collide - grow - and fall out of the sky as ________ - Most of it falls back into the oceans or onto land - where the precipitation flows over the ground as surface runoff - portion of run
