How do hotspots form?
Hotspots are thought to form due to mantle plumes. This is the upwelling of high temperature material from deep within the mantle. This high temperature material causes partial melting of the shallow mantle and overlying crust leading to a "hotspot" and volcanism.
What statement describes the asthenosphere?
Soft layer of the Mantle in which tectonic plates move.
Which layer of the earth does the magma form?
There is no layer of the Earth that is made of Magma (molten rock). There is a layer called the Mohorovicic Discontinuity (or Moho) which is the boundary between the Earth's lower crust and upper mantle. The asthenosphere is a mechanically weak ductily-deforming region of the upper mantle which lies below the Moho. The asthenosphere is thought to be the source of some magma but it is not a complete layer of molten rock.
How is oxygen circulated underground?
Oxygen can be circulated many ways through the Earth. Within the rock cycle, oxygen can be transported through magma within the molten outer core as well as the viscous inner mantle as part of molten silica and other minerals. Within the crust oxygen can be transported through aquifers, water tables, and permeable/semipermeable rocks. Plants also allow for some release and uptake of oxygen in their root systems.
Plumes of the molten rock originating deep within the mantle are known as?
Mantle Plumes
What regions was the result of plumes of hot mantle rising in a hot spot within a plate?
the islands of hawaii
Where does most intraplate volcanic activity occur?
Hot mantle plumes rise toward the surface within a plate

How did the mantle get its name?
The mantle is one of the three layers of the Earth. It was formed through the semi-solidification of hot, dense molten material deep within the Earth.
What molten liquid rock inside earths mantle is called?
The mantle is dominantly solid. Any molten material within it is generally called "melt" (used as a noun). It could also be correctly referred to as magma, but this usage is less common.
How do hotspots form?
Hotspots are thought to form due to mantle plumes. This is the upwelling of high temperature material from deep within the mantle. This high temperature material causes partial melting of the shallow mantle and overlying crust leading to a "hotspot" and volcanism.
How is the temperature and pressure in the Earth's mantle related to the depth of the mantle?
The degree of temperature and exertion of pressure by the molten materials (magma) within the mantle is directly proportional to its depth. This means that, the deeper you go down the mantle the higher the degree of temperature and pressure exerted.
When mantle plumes or hot spots erupt underneath moving plates which geologic feature results?
This process describes the creation of volcanoes. The eruption of the hot spot begins the generation of the magma within the volcano.
What statement describes the asthenosphere?
Soft layer of the Mantle in which tectonic plates move.
What is the definition of the medical term intrahepatic?
Intrahepatic means within the liver.situated or occurring within or originating in the liver
How did the galopagos island form?
The galapagos islands were formed from things called mantle plume. Other island were formed by this, like Hawaii. Mantle plumes are columns of hot rock from within the earth. They are about 100 kilometers in diameter and rise to the surface because they are so hot and therefore, less dense than the surrounding rock.
