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.
it is important because if the magma rises it becomes lava so if lava gets hot the volcano erupts

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!
A very long lived magma source located deep in the mantle is called?
A mantle plume. These plumes are thought to be responsible for hotspot volcanism, where magma erupts through the Earth's crust in localized regions, such as the Hawaiian Islands. The source of mantle plumes is still debated among geologists.
What is a hot plume model?
A hot plume model is a geological theory that explains the movement of magma through the Earth's mantle. It suggests that hot plumes of magma rise from the mantle to the Earth's surface, creating volcanic activity and forming features like hotspots and volcanic chains. This model helps to understand the formation of volcanic islands and other geologic phenomena.
Are hot spots above or below Earth's surface?
Hot spots are located below Earth's surface. They are stationary points where magma from the mantle plume rises and creates volcanic activity. Over time, as tectonic plates move, hot spots can create chains of volcanic islands on the Earth's surface.
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.
What occurs at a hot spot?
A hot spot is an area in Earth's mantle where a plume of hot magma rises to the surface, creating volcanic activity. This can result in the formation of volcanic islands or seamounts. Hot spots are believed to be stationary, unlike tectonic plate boundaries where volcanic activity is more common.
Do hot spots only form in oceanic crust?
No, hot spots can form in both oceanic and continental crust. Hot spots are areas of high volcanic activity that are thought to be caused by a deep-seated mantle plume that rises to the surface, creating a localized area of magma upwelling. These hot spots can create volcanic islands, such as the Hawaiian Islands, regardless of whether they are in oceanic or continental crust.
Why does magma form at a hot spot?
Magma forms at a hot spot due to the upwelling of hot mantle material from deep within the Earth. This heat source causes rock to melt, creating magma that can eventually make its way to the surface, forming volcanic eruptions. Hot spots are often associated with mantle plumes that bring heat from the core-mantle boundary to the surface.
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.
Are hot spots located over rising calderas?
Hot spots are not typically associated with rising calderas. Hot spots are regions of high volcanic activity caused by a fixed mantle plume that generates magma, while calderas are large volcanic craters typically formed by the collapse of a volcano after an eruption. However, hot spots can create volcanic activity that might eventually lead to the formation of calderas in certain cases.
Explain the relationship between hot spots and volcanism?
Hot spots are locations where magma from the mantle plume upwards towards the Earth's crust, creating volcanic activity. As the tectonic plate moves over the stationary hot spot, a chain of volcanoes can form, such as the Hawaiian Islands. This relationship shows how mantle plumes can directly contribute to volcanic activity at the Earth's surface.
What are Hawaiian Lava Beds made out of?
magma from hot spots in the crust
