The Diversity of Exoplanets: From Interior Dynamics to Surface Expressions

The coupled interior–atmosphere system of terrestrial exoplanets remains poorly understood. Exoplanets show a wide variety sizes, densities, surface temperatures, and interior structures, with important knock-on effects for this system. Many are predicted to have “stagnant lid” at the surface, rigid stationary crust, sluggish mantle convection, only minor volcanism. However, if Earth-like plate tectonics, which involves several discrete, slowly moving plates vigorous tectono-magmatic activity, then may be critical planetary habitability implications development (and evolution) life in galaxy. Here, we summarize our current knowledge dynamics context exoplanet diversity.
