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. Caldera. A large cauldron-like volcanic depression, a type of volcanic ...

How does the mantle move the crust? -

Jan 29, 2020 Secondly, how does the mantle move? Plates at our planet's surface move because of the intense heat in the Earth's core that causes molten rock in the mantle layer to move. It moves in a pattern called a convection cell that forms when warm material rises, cools, and eventually sink down. As the cooled material sinks down, it is warmed and ...

May 20, 2022 Mantle plumes emanating from the upper mantle may gush up through the lithosphere as hot spots. Mantle PlumesA mantle plume is an upwelling of superheated rock from the mantle. Mantle plumes are the likely cause of “hot spots,” volcanic regions not created by plate tectonics. As a mantle plume reaches the upper mantle, it melts into a diapir.
