  1. Final Review Honors Earth Science 2012

  2. Possible explanation to a problem is called • Law • Hypothesis • Conclusion • Observation

  3. What is evidence for the meteorite impact hypotheses? • Background radiation • Red shift • Blue shift • High iridium levels in rocks

  4. Red shift of galaxies is evidence for • Presence of radiation • Meteorite impact hypothesis • Destruction of ozone • Expansion of the universe

  5. A spectroscope is used to find a star’s • Position • Composition • Brightness • Origin

  6. Pangaea describes • A huge, ancient ocean • The earth • The Eurasian continent • An ancient single land mass

  7. What evidence shows that tropical areas may have once been much colder? • Coal deposits • Mountain chains • Glacial debris • Land bridges

  8. As rock moves from mid ocean ridges, it is replaced by • Continental crust • Molten rock • Microplate terranes • Older rocks

  9. Seafloor spreading occurs at • Subduction zones • Terrane boundaries • Transform boundaries • Divergent boundaries

  10. Layer of rock that flows under pressure • Crust • Asthenosphere • Lithosphere • Hydrosphere

  11. Rift valley is an example of a • Convergent boundary • Subduction zone • Transform boundary • Divergent boundary

  12. Located at a convergent plate boundary… • East coast of South America • Himalayan mountains • SF • mid Atlantic ridge

  13. Transfer of heat through the movement of fluid material • Tectonics • Convection • Paleomagnetism • Subduction

  14. Up and down motion of the crust • Thrust faulting • Strain • Isostatic adj • Compression

  15. A change in the shape or volume of rock due to stress is • Shearing • Isostasy • Folding • Strain

  16. Folding of rocks happen under • Tension • Shearing • Compression • Cooling

  17. Deeper rocks are more likely to fracture then ones closer to the surface because • Lower stress • Higher temperature • Higher strain • Lower altitude

  18. Causes reverse faults • Compression • Shearing • Tension • Folding

  19. Strike slip faults occur at • mid ocean ridges • Deep crust • Between grabens • On transform boundaries

  20. Continental - oceanic = • mid atlantic ridge • Cascades • Himalayas • Andirondacks

  21. Adjacent mountain ranges make up a mountain • Belt • System • Boundary • Ridge

  22. Apparent shift in the wavelengths of light coming from a moving source • Spectrum • Parallax • Doppler effect • Cepheid variable

  23. A galaxy moving toward earth would display • Red shift • Green shift • Yellow shift • Blue shift

  24. Apparent magnitude measures • Surface temperature • Distance from earth • Brightness as it appears from earth • Place on the HR diagram

  25. Earliest development of a star • Neutron star • Protostar • Nebula • Giant

  26. Stable because of fusion and gravity • Main sequence star • Neutron star • Pulsar • Supernova

  27. The most massive stars end up as • Dwarf stars • Super-duper giant • Empty hole • Black hole

  28. Milky way is a • Spiral galaxy • Irregular galaxy • Barred spiral • Elliptical

  29. Fusion in the sun produces • Hydrogen • Oxygen • Helium • Carbon

  30. Convective zone in the sun is surrounded by • Corona • Photosphere • Core • Chromosphere

  31. Layer that gives off visible light • Photosphere • Corona • Core • Chromosphere

  32. Ions streaming from the sun into space • Ozone • Solar wind • Solar nebula • Sunspot

  33. Sunspot cycle • 11 hours • 11 days • 11 weeks • 11 years

  34. Which is a gas giant • Mars • Venus • Neptune • Mercury

  35. Photosynthesis increased this in the atm • Carbon • Nitrogen • Hydrogen • Oxygen

  36. The End
