WebHot spots are found around the globe, on land and in the ocean. The Hawaiian Islands are the youngest volcanic mountains in a long chain of volcanoes that formed over a hotspot. They are still forming today. Another hot spot is under Yellowstone National Park, where the heat causes boiling mud pools and geysers like Old Faithful. WebA hotspot is a small area within the mantle which is of a higher temperature than the area surrounding it, and is usually associated with volcanic activity.. Formation: 1. A vertical column of magma rises up the mantle (it is lighter than the surrounding rock) – this is called a magma plume. 2. The magma plume pierces through the crust and heats the plate, …

"WebA volcanic "hotspot" is an area in the mantle from which heat rises as a thermal plume from deep in the Earth. High heat and lower pressure at the base of the lithosphere (tectonic plate) facilitates melting of the rock. This melt, called magma, rises through cracks and erupts to form volcanoes. As the tectonic plate moves over the stationary ... " - How are hot spots formed
