outer planet summary
Outer Planet Summary
  • Possible old volcanoes on Ganymede, and Europa similar to Enceladus?
  • Possible old volcanoes on Dione and Tethys?
  • Possible volcanoes on Pluto?
  • More data coming from New Horizons may answer some of these questions…
some questions to ponder
Some questions to ponder
  • What types of volcanoes are common to the Earth only? Why?
  • What types of volcanoes are common in the inner solar system but not the outer? Why?
  • What does this suggest about the cooling histories of the inner planets? Outer planets?
some questions to ponder1
Some questions to ponder
  • From the volcanoes we have seen which ones would we expect on which planets?
  • What do they suggest about other planets?
  • Since most of us do not live near a volcano, how can students connect volcanoes on the Earth and other planets?
