My fictional world is the same size and basic mineral makeup of Earth. It is also the third planet from its sun, the same distance we are from our sun. Except my Earth is much more volcanic. Or rather, it is more geologically active in general.
But how? If a planet was the same size, composition, etc of Earth, what would have to be different to contribute to a greater degree of volcanism? More silicon, uranium, sulfur, etc? Less plants? Less water? Would the planet have to be bigger, smaller, or closer to the sun?
I really like volcanoes. Always have, always will. My world will have as many volcanoes as safely possible. And the "how" might not matter to some authors, but additional requirements like more uranium or less distance from the sun may fuel the plot.
So what makes one earthlike planet more volcanic than another?
