Terrestrial Planet Evolution: Interior/exterior coupling, feedbacks and interaction

Terrestrial planets are complex systems. Their evolution is dependent on a wide array of different mechanisms and how they interact together. The aim of this session is to emphasize the importance of coupling between different layers of the terrestrial planets and feedback processes. For example, surface conditions are dependent on atmosphere composition, which results from early and on-going degassing, atmospheric losses and chemistry, and chemical reactions with the surface. In turn, surface conditions can affect the habitability of the planet. Changes in surface temperature affect surface alteration processes as well as volatile exchanges and might even govern the tectonic regime.
We welcome contributions focused on a single terrestrial body as well as from comparative planetology. Both solar system bodies and exoplanets studies are covered. This session will bring together scientists from a wide range of domains and examine how they can affect planetary evolution. Targeted disciplines include mantle dynamics, planetary structure and composition, tectonic regimes, geomagnetism, volcanism, surface interaction/erosion, atmospheric sciences, volatile cycling, climate and habitability.
