Did you know?
WebFurther, although Venus shows no evidence of Earth-like tectonic plates today, mantle convection might drive some horizontal motion and associated surface deformation (10, 11, 16–18), possibly facilitated by a weak lower crustal layer arising from the planet’s currently high surface temperature (∼740 K) (13, 19, 20). Web01. jan 2024. · A drastic change in plate tectonics and mantle convection occurred around 50 Ma as exemplified by the prominent Hawaiian-Emperor Bend. Both an abrupt Pacific Plate motion change and a change in mantle plume dynamics have been proposed to account for the Hawaiian-Emperor Bend, but debates surround the relative contribution …
