maybe hot outer core gas??
Because for the last 30 years scientistshave confirmed the existence of mantle plumes.Visual evidence.
mantle plumes
Mantle plumes result in the formation of hot spots.
All of the Earth's mantle is hot. And while some geologists believe that there are Mantle plumes (or hot spots) current evidence seems to support a view that mantle plumes do not exist. What causes magma to rise up from the lower crust and mantle is the convection of the mantle and therefore the places where most heat (and magma) is coming up to the surface is along the mid oceanic ridges.
i dont stupid know

The part of the tectonic plates located above mantle plumes are called "hot spots". --- Source(s) : Does Google count?
