Take Mars, the closest and most explored example. It has pretty much lost internal movement, thus magnetic waves that protect it from solar waves, and the solar wind has wiped off most atmosphere, and water. Question Does Mars have plate tectonics? Mars, it seems, once had active tectonic plates spreading away from long, narrow volcanic rifts, according to two reports in tomorrow's Science (pp. https://www.science.org › content › article › past-tecton... Past Tectonics on Mars? | Science | AAAS Why doesn't Mars have plate tectonics? Shaping the Planets: Tectonism Like Earth, Venus and Mars are believed to have hot interiors. This means that they are continuing to lose heat. While their surfaces show evidence of recent deformation — tectonism — neither planet has plate tectonic activity because neither planet has a surface divided into plates.
