Planetary Interiors

Delve into the mysteries of planetary interiors, minerals, and mass wasting, alongside surface geology and features like shield volcanoes, cinder cones, and impact craters. Uncover the unique landscapes shaped by volcanic activity, tectonics, and aeolian processes on celestial bodies like Mars, Io, and Europa through remote sensing data and imaging.

  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
