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.

6. Nearest galaxy - about 20 million light - years away






7. 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






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






9. Occur when two plates pull away from each other - Such faults are generally weak and shallow Example: the Mid - Atlantic Range in the Atlantic Ocean






10. Occur when two plates slip past each other - Such faults are generally moderate and are relatively shallow Example: The San Andreas Fault






11. The motive force behind land breezes and sea/lake breezes - also known as on - or off - shore winds - Land absorbs and radiates heat faster than water - but water releases heat over a longer period of time






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






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






14. Occurs at the instant when the sun's position in the sky is at its greatest angular distance on the other side of the equatorial plane from the observer's hemisphere - Depending on the shift of the calendar - the winter solstice occurs some time betw






15. 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






16. The science of the atmosphere and weather






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






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






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






20. Affected by factors such as weathering and impurities






21. Temperature - pressure - and composition






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






23. Method of using the present to interpret the past - Processes occurring today are observed carefully and their effects are measured - Then - geologists assume that similar effects in ancient rocks were caused by processes similar to those of the pres






24. The layers of sediment deposited in a quiet environment - Common sites of deposition are lakes - deltas at the mouths of rivers - beaches and sandbars along the coast - and (most important) the marine environment






25. Takes place when the moon passes between the earth and the sun - with the moon blocking the sunlight for about two minutes - A total ___________ may be seen only from a small zone on the earth






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






27. 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






28. The lateral movement of the plates is typically at speeds of ___ mm annually






29. Forms south of the Arctic and is cold






30. 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






31. 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






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






33. 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.






34. The earth is believed to be about ___ billion years old






35. Forms over water and is associated with wet air






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






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






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






39. Some precipitation falls as ____ and can accumulate as ice caps and glaciers - which can store water for thousands of years






40. 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






41. 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






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

44. Featherlike clouds that indicate fair weather






45. Large - scale movements of the earth's lithosphere - - The theory encompasses the older concepts of continental drift (first half of 20th century) and seafloor spreading (1960s)






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