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. 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)






2. 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






3. Occur along plate boundaries






4. 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






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

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






7. Faulting and folding






8. Giant masses of solid rock that float upon the earth's mantle - These plates move in relation to one another at one of three types of plate boundaries...






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






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






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






12. 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






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






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






15. 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






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

17. Featherlike clouds that indicate fair weather






18. 4 terrestrials: Mercury - Venus - Mars - Earth 4 gas giants: Jupiter - Saturn - Uranus - Neptune At least 5 dwarf planets: Ceres - Pluto - Makemake - Haumea - Eris






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






20. Cause pressure differences - A hot surface heats the air above it and the air expands - lowering the air pressure and its density






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






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






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






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






25. The sun and oceans can also affect the weather of land - If the sun heats ocean waters for a period of time - water can evaporate - Once evaporated into the air - the moisture can spread over nearby land - thus making it cooler

26. Affected by factors such as weathering and impurities






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






28. 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






29. Forms over land and is associated with dry air






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






31. Two types of mountains are formed - depending on how the rock reacts to the tectonic forces






32. 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






33. Sun heats water in the oceans - Water evaporates as vapor into the air - Ice and snow can sublimate directly into water vapor...- Over time - the water reenters the ocean - where the water cycle started






34. A major determiner of coastal climate






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






36. Piled in waves and indicate rain or snow






37. 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






38. Distance to closest stars can be calculated by measuring the _________ - a slight shift in apparent position against the background of more distant stars as the earth travels around the sun






39. Somewhat cooler disturbances in the photosphere






40. Occurs when the moon sets at sunset - Then the moon is between the earth and the sun - so we see only the dark half of the moon






41. The sun is not at the center of the disk - but out toward the perimeter - and is revolving around the ________






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






43. How much matter is in the object






44. 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






45. Classified as warm - water or cold - water currents






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






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






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






49. 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






50. Improved land - use practices can limit erosion by using techniques such as...
