• Studying planetary evolution from formation to
  the present day

Planetary evolution to the present day

• Dynamically-active interiors modify surface and
  atmosphere/ocean system over billions of years
• Wide range of behaviors plate tectonics, rigid
  lids, volcanic resurfacing, ice tectonics,
• Complications material properties, rheology,
  chemical differentiation

Internal dynamics Mantle
convection - powered by radioactive
elements and primordial heat
Earth
Much different in other bodies, e.g., Venus
Mars (rigid lid) and Io (magmatic heat loss)
