Is the Earth itself really a terrestrial planet? In many respects, the Earth differs from the other ones: It is the only one which has plate tectonics, a running geodynamo, oceans, a big moon, and pronounced climate zones, among others. What do terrestrial planets (including the larger satellites) have in common and how do they differ? Mars and Mercury show remnants of an earlier dynamo activity. Both of them and also Venus show surface tectonic features similar to structures observed on Earth. Volcanism is even observed on some satellites, such as Io and Enceladus, and maybe Titan. Why do Earth, Mars and Moon have dichotomies, while the Earth is the only planet with plate tectonics, whereas all others are one-plate planets? Perhaps this can be constrained from the structure and evolution of the lithosphere, which can be inferred from tectonic, thermal evolution and fluid-dynamical modeling.
The session aims for truly comparatively studies from many fields of planetology, such as interior dynamics (mantle, core, and dynamo), tectonics, volcanism, seismology, geology, or geomorphology. The above represents only a small selection of questions that may be adressed.
