Crust, salty ocean layer,not completely differentiated(shutdown of convection)Mercury Craters, streaks Has been geologically inactive forbillions of yearsMoon Craters, smooth areas Some shield volcanoes, volcanicdomes, presence of waterGanymedeStarburst patterns, some small craters,large slabs of darker materialEvidence of faulting / riftsEuropaMarsStreaks and scratches, some smallridgesCratered regions, large canyons,volcanoes, polar capsSmooth, young surface;tectonically active (water-icesurface) – possibly driven by warmplumes of water rising form deepinside the moonWas once tectonically active(straight line along Tharsis region);likely extinct nowIo Volcanoes See VenusVenus (Radar, then Elevation) Dendritic patterns, volcanoes Uniformly buoyant lithosphere(instead of negatively buoyant);melt-down 750 Ma (periodic),covering much of surface withvolcanism of some formACTIVITY: Region ProjectsStudents work in groups on computers. One computer can be used for research while the other oneis used for building a PowerPoint presentation. Groups continue work on parts 1-3 if necessary, andbegin working on parts 4-7.
