Hot spots are areas of volcanic activity located over rising?
Mantle plumes
What are continent-sized columns of superheated mantle material originating at the core-mantle boundary and rising upward due to a change in density?

What is mantle plume?
A mantle plume is a rising mass of extra hot mantle rock. Mantle plumes are though to be the cause of volcanic activity away from plate boundaries.
What is an area of volcanic activity that develops above rising plumes of magma?
Areas of volcanic activity that develop above rising plumes of magma are called hot spots.
Where does the lava emitted during volcanic eruption come from?
Magma originates either from rising plumes of heat at hot spots in the Earth's mantle, where decompression melting takes place as the hot rock nears the surface; or, it originates in the mantle from subduction of oceanic crust, where cold, wet rock speeds melting of the subducting rock and it rises toward the surface.Read more: Where_does_magma_and_lava_come_from
