magma comes from the outer core and when an earthquake or something happends, a crack froms and the pressure of lava shoots up like a geyser.
What else can I help you with?
Why does magma rise through the crust above it?
Magma rises through the crust due to differences in density between the magma and surrounding rock. Magma is less dense than the solid surrounding rock, so it moves upwards through cracks and fractures in the crust. As it rises, magma can also be driven by pressure differences and heat from the Earth's mantle.
Which of the Earth's layers does the magma come?
Magma is fluid molten rock that exists under the Earth's crust.
What are tectonic made of Magma and solid mantle crust and magma crust and solid mantle solid rock and molten rock?
Igneous rock
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.
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).
What is an area where magma from deep within the mantle melts through the crust above?
Hot spot.

Igneous rock
What is the hypothesis of volcanoes?
Magma from the mantle of the earth is forced up through fissures in the crust of the earth.
Where do you get your magma from?
Magma comes from the melting of material in the crust or upper mantle.
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.
Why does magma rise to the crust above it?
Magma rises through the crust above it because of pressure and depending on the magma (Pahoehoe or Aa). Pahoehoe is thin and runny and pours outside of the crust but, Aa is think and chunky and it can not pour out of a crack in the crust. It is more likely to blow out.
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).
Molten rock under the ground?
Molten rock under the ground is called magma. It is formed from the melting of rocks in the Earth's mantle. Magma can rise to the surface through volcanic eruptions, or it can solidify underground to form igneous rock.
Magma sometimes approaches or escapes onto Earth's surface Where does this magma form?
Magma typically forms in the Earth's mantle, which is a layer beneath the crust. It forms as a result of the melting of rocks due to high temperature and pressure within the mantle. This molten rock can then rise to the surface through volcanic activity.
Is magma released from volcanoes material from the core?
No, it's material from the mantle that is forced up due to partial melting of the subducting crust. As it forces its way up, it collects rock from the crust it is passing through and so the result is a mix of the crust and the mantle.
