How Volcanoes Work


  • Anonymous


Volcanism and associated plutonism have been dominant geologic processes from the earliest beginnings of our planet. Indeed, more than 80% of the Earth's surface is now, or originally was, of magmatic origin, and the distribution of volcanoes, past and present, reflects mantle and crustal dynamics within a context of plate tectonics. In recent decades, increasing attention has been paid to the study of the role of volcanism in global climate change. It is hardly surprising that since the flowering of the natural sciences in the 19th century, the question of how volcanoes work has been and remains one of the most fascinating and fundamental questions to challenge Earth scientists.
