How do hotspot volcanoes formed
WebThe Hawaiian Islands formed primarily as a result of volcanic activity. While most islands form near tectonic plate boundaries, the Hawaiian Islands are nearly 2000 miles away from the nearest plate margin. Therefore, scientists believe that the islands formed due to the presence of the Hawaiian "hot spot," a region deep in the Earth's mantle ... WebMost hotspot volcanoes are basaltic (e.g., Hawaii, Tahiti). As a result, they are less explosive than subduction zone volcanoes, in which water is trapped under the overriding plate. Where hotspots occur in continental regions, basaltic magma rises through the continental crust, which melts to form rhyolites.

WebHow is the formation of this type of volcano different than that of a hot-spot volcano? (6 points) Mt. Helens is formed on a subduction plate boundary, while a hotspot is formed because of mantle plumes, which are usually not on a plate boundary. 4. Most hot-spot volcanoes erupt through oceanic crust. A. Do these hot-spot volcanoes tend to ... WebHotspots are places where the magma rises up through the crust. They are caused by a static source of magma, often away from plate margins.
