Document Summary

November 21, 2013: planets that are closer to jupiter = more geologically active. Wouldn"t expect io to be geologically active b/c smaller than mercury and. More stretching when closer less when it"s farther rocks rub against one another during the process, creating heat. Europa"s interior is also liquid because of tidal heating: tidal heating is aka tidal friction, by the way, saturn"s moon enceladus has shown light leaking from cracks in its ice. Has basic building blocks of life (methane, water vapour, co2, simple organics) Collides with another ring particle b/c of invasion of orbit!
