What layer of the earth does most magma originate?
Most magma originates in the asthenosphere, which is a semi-fluid layer located in the upper mantle. Magma forms here due to the high temperatures and pressures that facilitate the melting of rock.
Where do mafic and felsic magma originate?
Felsic is a term that means that a rock contains types of silica. Fesic magma is magma that is high in silica particles and low in iron particles.
Does all magma come from the earths core?
No, not all magma comes from the Earth's core. Magma can also originate from the mantle, which is the layer beneath the Earth's crust. The heat and pressure from the mantle can cause rocks to melt and form magma, which can then rise to the surface as volcanic eruptions.
Where does magma originate?
Magma originates from the Earth's mantle, which is a layer of hot, semi-solid rock located beneath the Earth's crust. It forms when rocks in the mantle melt due to high temperatures and pressure. Magma can then rise to the Earth's surface through volcanic activity, such as volcanic eruptions.
Which is the most abundant in magma and has the greatest effect on its characteristics?
Silica is the most abundant component in magma and has the greatest effect on its characteristics. The amount of silica present determines the magma's viscosity, which in turn influences the explosiveness of volcanic eruptions.
What layer of the earth does most magma originate?
Most magma originates in the asthenosphere, which is a semi-fluid layer located in the upper mantle. Magma forms here due to the high temperatures and pressures that facilitate the melting of rock.
Where does granite and basalt come from?
Both originate as molten magma but in the case of granite the magma is acidic and in the case of basalt the magma is basic.

What is most magma?
magma
What type of magma is most likely under the crust?
magma
From where do most of the cranial nerves originate?
Most of the cranial nerves originate from the brainstem.
Does all magma come from the earths core?
No, not all magma comes from the Earth's core. Magma can also originate from the mantle, which is the layer beneath the Earth's crust. The heat and pressure from the mantle can cause rocks to melt and form magma, which can then rise to the surface as volcanic eruptions.
What does most Most magma form from?
Magma is the result of partial melting of crustal rocks. It is a eutectic melt product.
What is the origin on most hydrothermal solutions?
Most hydrothermal solutions originate from groundwater that has been heated by magma deep within the Earth's crust. This heated water can rise to the surface through cracks and fractures, carrying dissolved minerals with it.
What are convection current and how are they formed?
Convection currents in the earth originate in the mantle. The liquid moves in a circle pattern as the hotter magma rises and the cooler magma falls. This can also be observed in any fluid material, gases or liquids.
Where does magma originate?

Where is most of the magma at?
Under the crust.
