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.


Which theory of plate movement involves magma rising all the way from the lower mantle to spread apart?

Hot Plumes

Hot Plumes


Which theory of plate movement involves magma rising all the way from the lower mantle to spread the plates apart?

How can one mantle plume form several volcanic islands?

Mantle plumes appear to remain nearly stationary. However, the lithospheric plate above a mantle plume continues to drift slowly. So, the volcano on the surface is eventually carried away from the mantle plume. The activity of the volcano stops because it has moved away from the hot spot that supplied it with magma. A new volcano forms, however, at the point on the plate's surface that is now over the mantle plume. Some mantle plumes are long and linear. As magma generated by these plumes rises through cracks in Earth's crust, a line of hotspot volcanoes forms. Unlike volcanoes that form individually as a plate moves over a mantle plume, hot-spot volcanoes that form in lines over a long plume do not have any particular age relationship to each another.Mantle plumes appear to remain nearly stationary.

Area in the Earth's mantle hot enough to melt rock into magma and create volcanoes?

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.

What is wrong with this. What if team magma did not appear in the submarine?

Team Magma will not appear in the submarine but you will see them get away with it the first time. The second time you see the submarine, you have to dive to the seafloor cavern to go challenge Maxie.
