Answer 1

Scientists wondered how volcanoes could be located so far from tectonic plate boundaries until one proposed the idea of hotspot volcanism, where the magma is much hotter than the surrounding magma. These hotspots are stationary and do not move the tectonic plates. They are responsible for the creation of volcanic island chains.
