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. Used to arrange strata in a standard order - Used to measure the amount of radioactive decay in minerals and calculate the time at which the rock formed






2. Test the item against materials of known hardness; for example - use your fingernail or the graphite in a pencil to attempt to scratch the items. This process should result in assigning a relative hardness to the unknown items.






3. 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






4. 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






5. 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)






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






7. The degrees north or south of the equator






8. The science of the atmosphere and weather






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






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






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

12. Featherlike clouds that indicate fair weather






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






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






15. 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






16. 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






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






18. Igneous rock that forms on the earth's surface - Examples obsidian - basalt - and pumice






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






20. Different visual appearance; when discovered - comets show a perceptible coma while asteroids do not






21. An area of frequent earthquakes and volcanic eruptions associated with the plate boundaries surrounding the Pacific Ocean - In a 40000 km horseshoe shape - associated with a nearly continuous series of oceanic trenches - volcanic arcs - and volcanic






22. 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






23. Human civilization has lasted only _____ years






24. The atmosphere is a __________ - and so small changes to one part of the system can grow to have large effects on the system as a whole - This makes it difficult to accurately predict weather more than a few days in advance






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






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






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






28. Mountains blocking the path of precipitation to the desert






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






30. Occur along plate boundaries






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






32. 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






33. Seas - gulfs - bays - and other names






34. 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

35. Solar Atmosphere is divided into the inner chromosphere with explosive prominences and the outer corona - a glowing halo visible only during a total eclipse - Constantly emitting particles as a...






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






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






38. 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






39. The flow of water underground - in the vadose zone and aquifers - Subsurface water may return to the surface (as a spring or by being pumped) or eventually seep into the oceans






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






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






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






43. Bodies similar to the sun but immensely distant - Closest stars are 4 light - years away






44. 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






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






46. Volcanoes can be caused by '____________'; these so - called hotspots - as in Hawaii - can occur far from plate boundaries






47. Sometimes called minor planets or planetoids - Bodies






48. The transformation of water from liquid to gas phases as it moves from the ground or bodies of water into the overlying atmosphere






49. A region of the earth that has uniform standard time - usually referred to as the local time - divided into standard and daylight saving (or summer)






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