One possible theory is that hot spots form as a direct result of ________. A. a non-stationary zone in the crust that is hotter than the surrounding area. B. an increase in temperature due to the friction caused as plates move and bump into each other. C. a mantle plume which causes melting at the surface allowing magma to escape. Reset Selection

One possible theory for the formation of hot spots is the presence of a mantle plume—an upwelling of abnormally hot rock within the Earth's mantle. This rising plume of hot material can lead to melting at the Earth's surface, creating magma chambers and, subsequently, volcanic activity. Hot spots are often associated with volcanic features such as shield volcanoes and can be relatively stationary over geologic time, even as tectonic plates move.
