From mass-radius measurements that inform about bulk planet composition, we are moving to detailed atmospheric spectroscopy that unravels atmosphere composition. While the observations of atmospheres of intermediate-sized and small exoplanets keep growing, the understanding of planetary interiors and interior-atmosphere interactions is more vital than ever. In this overview talk, I will focus on terrestrial-type exoplanet interiors and evolution from a perspective of chemical and physical diversity. The interior composition, mineralogy and structure are largely determined by the inventory of refractory elements. The interior evolution and atmospheric chemistry are further influenced by the inventory of volatile elements. I will discuss the role of exoplanet interiors on the composition of atmospheres including processes such as geochemical cycling, outgassing and atmospheric escape. Going forward, we will need to develop a thorough understanding of planetary mineralogy, material properties and processes that take place outside the physical and chemical realms of Earth and planetary bodies in the Solar System with the help of theoretical models and laboratory experiments.
