The evolution of planetary bodies involves a variety of physical and chemical processes interacting over a very large range of scales in space and time.
With the progress of computational resources and the increasing set of
experimental constraints, more and more physics and scales can be dealt
with in numerical models of terrestrial planets. On the other hand, more
and more of these bodies, sometimes exotic ones, are discovered in other solar systems, making the understanding of thermal and chemical evolution of terrestrial planets a crucial knowledge to improve in order to understand these new bodies.

In this session we invite contributions from fluid-dynamic and geophysical investigations ranging from global models investigating the long-term thermal and thermochemical evolution of terrestrial planets to local and short-term geodynamical investigations.
