WebWhy do hotspots form volcanic island chains? Because plate moves over a stationary hotspot The three major types of geologic settings for volcanoes are: Subduction zones, hot spots, mid-ocean ridges Active volcanoes in the Pacific coastal states of the USA are caused by: Subduction In geology, hotspots (or hot spots) are volcanic locales thought to be fed by underlying mantle that is anomalously hot compared with the surrounding mantle. Examples include the Hawaii, Iceland, and Yellowstone hotspots. A hotspot's position on the Earth's surface is independent of tectonic plate boundaries, and so hotspots may create a chain of volcanoes as the plates move above them.
