Question

Given the nature of explosive volcanic eruptions here on earth and the important roles of dissolved gases and plate tectonics, what might you expect of volcanoes erupting on other planets?

Answer 1

It is likely that volcanoes on other planets play similar role in shaping their geological structures and also in maintaining the content of gases in the atmosphere. The combination of these roles played by volcanoes make volcanoes a vital part of any planet's geological systems.
