How hotspots create volcanic island chains
Did you know?
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. Web8 jul. 2024 · As a lithospheric slab is being subducted, the slab melts when the edges reach a depth which is sufficiently hot. Hot, remelted material from the subducting slab rises …

WebThis chain has formed as the Pacific Plate moved northwest over a hot spot (Steven Earle, “Physical Geology”). Since most mantle plumes are beneath the oceans, the early stages of volcanism typically take place on the seafloor. Over time, very large islands may form like those in Hawaii. Web4 jun. 2024 · Answer: This melt, called magma, rises through cracks and erupts to form volcanoes. As the tectonic plate moves over the stationary hot spot, the volcanoes are rafted away and new ones form in their place. This results in chains of volcanoes, such as the Hawaiian Islands.
WebAnalysis. 1. The presented diagram details an island chain in Hawaii located in the Pacific Ocean. 2. Looking from an overall perspective, it is readily apparent that volcanic formation begins deep under the Earth’s mantle and is visibly the result of multiple eruptions over the years.
