Our neighbouring planet Venus presents a clear contrast of tectonics with the Earth, despite similar interior structure and composition. Despite the absence of plate tectonics, its surface is littered with volcanic structures, rifts, and mountains. To what extent these surface features reflect the current state of the planet’s interior, remains in question. A better understanding of the dynamic interior processes at play, and how they link to the planet’s surface, is key for our understanding of the geological evolution of rocky planets (such as Earth), and even their habitability.
