Billions of years ago loads of rocks collided with each other creating friction. this created earth and the heat generated by the friction still hasn't died down, it melted rock and made magma.
I still believe the melting of solid ro ck magma is a function of three variables, the pressure, composition and the resulting heat. Magma is constantly discharged and renewed this is the force behind sea floor spreading.

∙ 12y agoMagma is the term used to describe the molten material that forms in the crust or the mantle and can be considered molten rock. The core is primarily composed of iron and nickel. There is very little silicon (which is one of the most important ingrediants of rock forming minerals) and so there is very unlikely to be "magma" in Earth's core. However that being said, at the core-mantle-boundary where the very high temperature outer core meets the much cooler mantle, significant melting of the mantle material occurs and there is the possibility of limited intermixing of the two phases although there significant differences in density would make this difficult.

Is magma push up through cracks in the earth's crust?
No its in the earth center or core if you will. Lava is outer magma is inner and the difference is the heat magma hotter lava's cooler but both are over 1000 degrees.
Magma that has emerged from the earth?
Magma that has emerged from the earth is basically lava.....
How does solid rock usually become magma?
As rock is pushed down toward the the Earth's center it gets hotter and hotter.
Which of the Earth's layers does the magma come?
Magma is fluid molten rock that exists under the Earth's crust.
What is the molten rock found beneath the surface of the earth?
Molten rock beneath the earth's surface is called magma.
Is it hot in the center of the earth?
Yes. Magma comes from the center of the Earth, and magma is very hot. That indicates that the inside of the Earth must be hot too.
What is close to the center of the earth but liquid?
The closest liquid to the Earth's core that is known is magma.
What the center of the earth?
The center of the earth is the core. It is full of molten hot magma. It is generally pictured as red when seen in drawings.

What is another name for center of earth that starts with a M?
mantle, magma
Is the equator the center of the earth?
No the centre of the earth id made up of molten rock and magma.
Why is center of earth hotter than surface of earth?
Our core, is hot because it is basically made up of magma (lava) and red hot iron. The magma, is stored there, and that is where the volcanic magma comes from.
Is magma push up through cracks in the earth's crust?
No its in the earth center or core if you will. Lava is outer magma is inner and the difference is the heat magma hotter lava's cooler but both are over 1000 degrees.
Where would you most likely find magma at the earth's surface?
At an erupting volcano.
What is Igneous rock is made from?
They are made from cooled lava, because they come from volcano's, and the center of the earth, which has magma (lava) flowing around.no
Is there a center of the earth?
Well, TECHNICALLY, there is a center of the earth, but it is filled with magma up to 10,000 Degrees Fahrenheit that can instantly disintegrate you're body Nothing that can let us go there.
Which place is at center of the world?
There is no real "center" of Earth, if you are talking about on the surface. Since Earth is a sphere, the only center it would have is the core, which is impossible to get to because it is completely liquid magma. The mantle will kill you if you go through the crust.
