On modern Earth, the dominant tectonic activity is called plate tectonics, where oceanic crust — the outermost layer of the Earth under the oceans — sinks into the Earth’s mantle (the area between the Earth’s crust and its core) at points of convergence called subduction zones.

Convection currents of very hot molten rock in the mantle constantly push and pull these plates around in a process known as plate tectonics.

Convection happens when hotter material rises and cooler material sinks, and that process is what powers plate tectonics here on Earth.

This phase of habitability could have lasted for up to ~900 Myrs if Venus has always been in a stagnant lid tectonic regime18, or if early Venus had Earth-like plate tectonics then this habitable period could have lasted for up to 4 Gyrs, until runaway greenhouse was instigated by voluminous magmatism17.

Venus’s greenhouse effect is exacerbated by its apparent lack of plate tectonics.

On Earth, this can be aided by our oceans of water and plate tectonics, but without these key ingredients on the moon, planetary scientists have been left to wonder how these domes formed and evolved over time.
