  5. Tectonics

  6. Plate Tectonics

  7. Volcanoes

  8. Landforms • Shield Volcano (Hawaii) • Cinder Cone (Lassen National Park) • Stratovolcano (Mt. Shasta, California

  9. Hot features • Fumaroles • Hot springs • Geysers

  10. Wind

  11. Dunes

  12. Alluvial Fan

  13. Impact Craters

  14. Terrestrial Impact Craters • Meteor Crater, AZ • Manicouagan, Canada • Chicxulub, Yucatan, Mexico

  15. Impact Frequency

  16. Surface Geology of Individual Bodies • Remote Sensing • Imaging • Photometry • Thermal and reflectance spectra • Radar and radio observations

  17. Moon • No atmosphere • Two primary terrains • Highlands • Old, highly cratered • Maria • Younger, darker • Volcanism • Maria • Tectonism • rilles

  18. Mercury • Primarily covered with impact craters • Caloris Basin • No obvious volcanism • Tectonism • Long, sub-linear scarps • Likely produced by planetwide contraction • Decrease in Mercury’s radius by 1-2 km

  19. Venus • Bulk properties similar to Earth • Features dominated by Volcanism • Also see • Impact craters • Tectonism • Erosion

  20. Volcanism

  21. Craters, Tectonics, & Wind

  22. Mars • Crustal Dichotomy • Southern cratered highlands • Northern lowlands • All surface processes have visible features • No obvious active volcanism and tectonism • Dead world? • Most new research

  23. Water • Channels • Teardrop islands • Fluidized ejecta blankets

  24. Aeolian Features

  25. Io • Few impact craters • Most volcanically active body in solar system • Tectonics, erosion

  26. Olympus Mons 27 km high 550 km across 102 km diameter caldera Loki 200 km diameter Largest Volcano

  27. Europa • Icy surface • Processes • Tectonics • Volcanism/erosion • Cratering

  28. Cassini at Saturn • http://saturn.jpl.nasa.gov/home/index.cfm

  29. More Titan
