WebSep 6, 2024 · A hot spot is a region deep within the Earth’s mantle from which heat rises through the process of convection. This heat facilitates the melting of rock. The melted rock, known as magma, often pushes through cracks in the crust to form volcanoes. Instead it occurs at abnormally hot centers known as mantle plumes. WebWell, back in 1963, a geophysicist by the name of Wilson came up with a hot-spot theory to explain how this particular type of volcanic activity can occur, and can go on for maybe tens or even hundreds of millions of years.Wilson's theory was that: hot spots exist below tectonic plates, and they're the cause of these volcanoes.

WebSep 16, 2024 · How do hotspots form quizlet? A hotspot forms when a plume of magma rises from the mantle and melts through whatever crust is above it. This new magma tries to reach the curface and creates a volcano. But when the tectonic plate shifts, new crust is suddenly above the hotspot, and a new volcano forms. Hotspot volcanoes erupt slowly … WebAt a convergent plate boundary, one plate dives or “subducts” beneath the other, resulting in a variety of earthquakes and a line of volcanoes on the overriding plate. Another feature associated with volcanic activity is a hotspot, where a rising plume of hot mantle can lead to volcano formation at the surface. collier county school board fl
