Volcanism on Earth is known to occur in three tectonic settings: divergent plate boundaries (such as mid-ocean ridges), convergent plate boundaries … WebbMost of our planet's volcanism occurs near plate boundaries, well explained by plate tectonic processes. In turn, intraplate volcanisms are not readily explained by plate tectonics, but often resort to mantle processes (Ballmer,vanKeken,etal.,2015;Ballmer,etal.,2016;Burkeetal.,2008;Morgan,1971;Tan&Gurnis,2005; …

WebbThe Earth's internal heat source provides the energy for our dynamic planet, supplying it with the driving force for plate-tectonic motion, and for on-going catastrophic events such as earthquakes and volcanic eruptions.
