Venus’ surface is not a single, solid “lithosphere”, as once thought, but a patchwork of tectonic plates with similar activity to – but not the same as – those here on Earth, according to a new study out today inProceedings of the National Academy of Sciences.
The study shows that these tectonic plates jostle and bump against one another like pack ice on a frozen lake, suggesting Venus is still geologically active.
“We’ve identified a previously unrecognised pattern of tectonic deformation on Venus, one that is driven by interior…
