How do hot spot form
WebMar 3, 2024 · Most 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. WebFeb 11, 2024 · Where the lava is hot and free to flow, it forms a smooth, ropy surface, known as pahoehoe (“puh-hoy-hoy”). When the lava flow cools down it becomes more sluggish, forming a surface of broken, jagged blocks called aa (“ah-ah”). Aa flows can be very difficult and dangerous to walk across, tearing boots to shreds. Hawaii Volcanoes National Par k

WebMay 6, 2024 · In geology, the places known as hotspots or hot spots are volcanic regions thought to be fed by underlying mantle that is anomalously hot compared with the surrounding mantle. They may be on, near to, or far from tectonic plate boundaries. Currently, there are two hypotheses that attempt to explain their origins.

WebA volcanic “hotspot” is an area in the mantle from which heat rises as a thermal plume from deep in the Earth. 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.
