In this session, we will share diverse approaches and ideas exploring the evolutionary pathways of terrestrial planets as complex systems. Their evolution is dependent on a wide array of different mechanisms and how they interact together. Based on present-day observation of examples within our Solar System, and simulations, we wish to foster discussion of models of planetary development: is there a general evolution pattern or is the process stochastic? The aim of this session is also to emphasize the importance of coupling between different layers of the terrestrial planets and feedback processes. Those are still often under-explored and have potentially major repercussions on planetary evolution. 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, with a multi-disciplinary outlook, and examine how they can affect planetary evolution. Targeted disciplines include planetary structure and composition, mantle dynamics, tectonic regimes, geomagnetism, volcanism, surface interaction/erosion, geochemistry, petrology, remote sensing, structural geology, atmospheric sciences, volatile cycling, climate and habitability.
