WebVolcanoes can erupt with massive force, as a small explosion, or just a steady dribble. Deep underneath Earth’s outer, rocky layer, which is called the crust, the rock is not all solid. In some places it has melted into a very hot liquid called magma. The magma rises through a gap in the crust and is trapped in an area called a magma chamber. WebScientists don’t fully understand how and why hotspots occur, and there is vigorous scientific debate about their origins. A frequently-used hypothesis suggests that hotspots form over exceptionally hot regions in the mantle, which is the hot, flowing layer of the Earth beneath the crust. Mantle rock in those extra-hot regions is more buoyant ...
