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. The runoff produced by melting snow






2. 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






3. Precipitation - Canopy interception - Snowmelt - Runoff - Percolation - Subsurface flow- Evaporation - Sublimation - Condensation






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






5. Some water infiltrates deep into the ground and replenishes ________ - which store huge amounts of freshwater for long periods of time






6. 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






7. 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






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






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






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






11. 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






12. Forms over land and is associated with dry air






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






14. 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






15. Water returns to the land surface at __________ than where it entered - under the force of gravity or gravity - induced pressures






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






17. The state change where a solid (ice or snow) changes directly to a gas (water vapor)






18. Maritime polar (wet - cold air)






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


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






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






22. 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






23. Gas giants Jupiter - Saturn - Uranus and Neptune have diameters far larger than Earth's and have far greater masses






24. How much matter is in the object






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






26. Due to a combination of differential heating and geometry - hen the sun rises - it is the tops of the mountain peaks which receive first light - and as the day progresses - the mountain slopes take on a greater heat load than the valleys - This resul






27. Seas - gulfs - bays - and other names






28. 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






29. Continental polar (dry - cold air)






30. Somewhat cooler disturbances in the photosphere






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






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






33. The breakdown of rocks - soils and minerals through direct contact with atmospheric conditions such as heat - water - ice - and pressure






34. Water transpired from plants and evaporated from the soil






35. Featherlike clouds that indicate fair weather






36. 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






37. Faulting and folding






38. The major mountains tend to occur in __________ - indicating tectonic plate boundaries and activity






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






40. 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






41. 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






42. Formed by sodium chloride






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






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






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






46. Both gravity and inertia work together to keep planets in orbit around the sun - Inertia makes a planet travel in a straight line






47. Occur twice a year - when the tilt of the earth's axis is oriented neither from nor to the sun - causing the sun to be located vertically above a point on the equator - The name derived from the Latin aequus (equal) and nox (night) - because at the e






48. Forms south of the Arctic and is cold






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






50. Center: 3000
