Planetary volcanism across the Solar system / Планетарный вулканизм через Солнечную систему

Earth’s infinite geological complexity fascinates us, and centuries of detailed observations and modeling can tempt us to believe that we have a full understanding of Earth’s igneous processes. Our world, however, is only one data point in the Solar System. A model that successfully predicts or explains a volcanic process on Earth, for example, may fail completely when applied to another planetary body. Such comparative planetology is therefore critical, and reveals the weaknesses in our understanding that would otherwise remain hidden: just because a model works on Earth does not mean that it truly explains a given process elsewhere using first principles. <...>
