What are the fundamental questions about Earth's deep interior that remain unanswered, and how can the study of hotspots help address them?

May 6, 2022 ... Most hotspot volcanoes are basaltic (e.g., Hawaii, Tahiti). As a result, they are less explosive than subduction zone volcanoes, in which water ... This lies at a fixed position under the Tectonic Plate. As the plate moves over this “hot spot”, the upwelling lava creates a steady succession of new volcanoes ... Sep 13, 2022 ... yes. given the right geologic setting, and right ammount of time, mantle plumes can form anywhere. Plus there already ARE monogenetic, plume fed ... In an oceanic hotspot environment, for example Hawaii, dark, silica-poor basalt magma is produced. The runny basalt forms broad sloping shield volcanoes (Fig. 6) ... A volcanic hotspot is where magma pushes up from deep in the Earth's crust or mantle, and creates a volcano. It is a type of unique volcanism because most frequently volcanoes develop in the boundaries of tectonic plaques. The best well known examples of hotspot ... It is this that fuels a chain of volcanoes, such as the Aleutian Islands, near Alaska. Hotspot volcanic chains. The joint mantle plume/hotspot hypothesis ... A volcanic "hotspot" is an area in the mantle from which heat rises as a thermal plume from deep in the Earth. High heat and lower pressure at the base of the ... Jul 3, 2016 ... The volcanoes of Hawaii, Iceland, the Galapagos and Yellowstone form from plumes of mantle beneath the surface, making them hotspot volcanoes. intraplate, hotspot volcano, on four occasions from February 1987 to September 1990. ...
