I think you may mean a mantle plume. This is an idea that there are large upwellings of the mantle into the crust, which create 'hot spots'. They were posited to explain such features as the volcanic Hawaiian islands which do not stand on a plate boundary. It is not a generally accepted idea and other theories seem to be gaining more acceptance.

When magma heats underground water the result may be?
When magma comes in contact with underground water, it creates hot springs, or geysers.
Explain how scientist tink most magma is formed?
Magma is formed from the subduction and melting of cold, dense, wet oceanic crust at some convergent plate margins. The moisture in the rock assists in the melting of the crust and the rock surrounding it. Magma is also formed at hot spots in the mantle where hot material undergoes decompression melting as it rises. Decompression melting also occurs at the mid-ocean ridges where new oceanic crust is formed from rising mantel rock.
Is lava a plasma?
Magma is not plasma since plasma is neither solid ,liquid or gas while magma is always solid when cool and liquid when hot.
What is the Molten liquid rock inside Earth's mantle called .?
Molten rock in any of Earth's layers is called magma. The mantle is actually composed of solid, but very hot and plastic-like rock.
Why is hot water important?
to make hot chocolate!
What is a hot plume model?
The theory that plates diverge where large columns of hot magma, called hot spots, rise from the lower mantle
A very long lived magma source located deep in the mantle is called?
The term hot spot is used to describe a very long-lived magma source located deep in the mantle. J. Tuzo Wilson is credited with having originated the concept of hot spots.
How do you briefly explain how volcanoes that are located in hot spots formed?
As tectonic plate moves over a mantle plume, rising magma causes a chain of volcanic islands to form.
Explain how volcanoes that are located at hot spots form?
Volcanoes located at hot spots form by lying directly above columns of hot rock that rise through Earth's mantle. As a tectonic plate moves over a mantle plume, rising magma causes a chain of volcanic islands to form.
What are columns of rising magma?
hot spots
What forms to a mantle plume?
Mantle plumes result in the formation of hot spots.
What causes magma to form at hot spots?
A volcanic hot spot forms from upwelling magma usually due to the subduction of a tectonic plate. As plates move over this area new volcanoes are formed. +++ A hot spot alone is the top of a convection plume in the Mantle, not above subduction. This type of hot spot can lead to continental rifting.
Why does magma form at a hot spot?
Magma form at a hot spot due to a focusing of conditions that lead to melting. This is sometime caused by a mantle plume, but is NOT always the case.
What is a hot spot volcano?
A volcano formed by a rising plume of magma that is not located at a plate boundary.
What causes hot spots on earth?
The flow of molten magma is what causes varying hot spots on Earth. Hot spots are also known to heat water beneath the ground.
How does a hot spot make a chain of volcano mountains?
A hot spot deep in the Earth's mantle creates a rising plume of magma that is even hotter than the regular magma of which the mantle is composed. When this plume of magma hits the crust, it breaks through and causes a volcano. The reason why we eventually wind up with a whole chain of volcanoes, rather than just one, is continental drift. The Earth's crust is moving, while the plume of magma is always directed at the same spot, so as the tectonic plate slowly drifts by, the plume will impact different parts of that plate.
Large rising bodies of magma not at plate boundaries?
hot spots
