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.
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.
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 most magma originate?
Most magma originates from the Earth's mantle, which is the layer beneath the crust. Magma forms due to the melting of rocks under high temperatures and pressures deep within the mantle. This molten rock can then rise towards the Earth's surface through volcanic activity.
What are large rising bodies of magma not at plate boundaries called?
A large rising body of magma is called a magma plume they originate from the mantle. Plate boundaries are found at the edge of the lithospheric plates and are of three types, convergent, divergent and conservative.
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 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.

Why are molten rocks found near volcanoes?
Molten rocks, known as magma, are found near volcanoes because they originate from deep within the Earth's mantle. The extreme heat and pressure in the Earth's interior cause rocks to melt and form magma, which can rise to the surface through volcanic activity, creating volcanoes.
How are magma rocks and lava rocks alike?
Magma rocks and lava rocks are both formed from molten rock beneath the Earth's surface. They both originate from the same source material but differ in their location and state - magma rocks are found below the surface, while lava rocks are formed when magma reaches the surface and cools.
What magma is silica-rich thick magma?
An acid magma or a granitic magma.
What is alkaline magma?
Alkaline magma is a type of igneous magma that is rich in alkaline elements, such as sodium and potassium, and has a low silica content. This composition typically leads to the formation of volcanic rocks like phonolite and trachyte. Alkaline magmas often originate from deeper mantle sources and can produce explosive volcanic eruptions, characterized by unique mineralogy and geochemical properties. They are commonly associated with rift zones and hotspot volcanism.
Does every volcano form in the mantle?
No, the Earth's mantle is to deep and warm for this. Magmas are generated in the upper mantle by a process called partial melting and the melt collects in the crust (in magma chambers at varying depth).
