1. Are studies being done on Io’s volcanic actions? Are Io’s processes the same as ours—caused by tectonics?
Volcanoes on Io look virtually identical to volcanoes on the Earth. That means the processes of eruption are the same—melted materials at depth working their way up to the surface through cracks and buoyancy forces. However, Io does not display plate tectonics: the volcanoes are more or less randomly distributed and there are no correlated belts of mountains and trenches (subduction zones) such as on Earth.
