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.

2. Erosion in many places is increased by human land use - Poor land - use practices include deforestation - overgrazing - unmanaged construction activity - and road building






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






4. 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






5. At any given time - regardless of season - the Northern and Southern Hemispheres experience...






6. Forms over the Tropics and is warm






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






8. The North Pole is in the Arctic Ocean - and thus its temperature extremes are buffered by the water - The result is that the South Pole is consistently _______ during the southern winter than the North Pole during the northern winter






9. Forms over water and is associated with wet air






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

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






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






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






15. Faulting and folding






16. Mountains blocking the path of precipitation to the desert






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






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






19. 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






20. Further caused by the elliptical orbit of the earth - Earth reaches perihelion (the point in its orbit closest to the sun) in January - and it reaches aphelion (farthest point from the sun) in July - Also depend on factors such as proximity to oceans






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






22. 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






23. An opening - or rupture - in a planet's surface or crust - which allows hot molten rock - ash - and gases to escape from below the surface - Volcanic activity involving the extrusion of rock tends to form mountains or features like mountains over a p






24. The science that describes and interprets the earth Fields: - Geomorphology (land forms) - Petrology (rocks) - Stratigraphy (layered rocks) - Paleontology (fossils)






25. A natural flow of water - usually freshwater - traveling toward an ocean - a lake - or another stream






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






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






28. The tendency of a moving object to stay in a straight line or a stationary object to remain in place - Without _______ - a planet would be pulled into the sun






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






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






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






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






33. Seas - gulfs - bays - and other names






34. Temperature - pressure - and composition






35. Tides may be...






36. Human civilization has lasted only _____ years






37. Large - dark clouds that indicate thunderstorms






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






39. 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






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






41. The process in which one type of rock changes into another






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






43. Travels around the earth each month - - Distance from the earth averages 237000 miles - Has rugged topography formed billions of years ago by volcanic eruptions and meteorite impacts - Mass is 1/6th that of Earth






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. Younger beds were originally deposited above older beds






46. The strong temperature contrast between polar and tropical air gives rise to the ________
