Is there evidence for extraterrestrial plate tectonics if so where?

Yes, there is evidence for extraterrestrial plate tectonics on several celestial bodies, most notably on Earth’s neighbors like Mars and some of Jupiter's moons, such as Europa. Mars exhibits features resembling tectonic fault lines and rift valleys, suggesting past tectonic activity. Europa is believed to have a subsurface ocean beneath its icy crust, with geological features indicating potential tectonic processes. Additionally, Venus displays large-scale tectonic features, though its processes may differ from those on Earth.
