GEOLOGY 1 Lecture Notes - Lecture 27: Metallic Hydrogen, Liquid Hydrogen, Tidal Power
Document Summary
Jupiter large but not very dense, mostly gases. Core region (solid) is surrounded by dense metallic hydrogen, which extends outward to about 78% of the radius of the planet. Io ( galilean satellites jupiter"s moons) Volcanoes on io caused by contraction and expansion of planet caused by its position from jupiter. Volcanic plumes on io - fountains of lava gushing 160 km in height. Io without atmosphere, so lava ejected into space. Core similar to earth surrounded by a deep layer of metallic hydrogen, an intermediate layer of liquid hydrogen and liquid helium and an outer gaseous layer. Saturn"s density is so low it would float on water. A rocky center, an icy mantle and an outer gaseous hydrogen/helium ice dominating over gases = ice giants envelope ice: water, ammonia and methane. Triton contains cryovolcanism (ejects ice, ammonia, other not molten rock) We can see a plume from a geyser (wind ?)
