Why is magma in the center of earth?

Answer 1

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.

Answer 2

Magma 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.

Answer 3

Magma is in the center of the Earth because of the intense heat and pressure in the planet's core. As the materials in the core heat up, they melt and form magma. This molten rock then rises towards the Earth's surface through volcanic activity.

Answer 4

No. The inner core is most likely a solid iron-nickel alloy, and the outer core is molten iron and nickel.

Answer 5

It is under enormous pressure which help keeps it hot but current theories believe that radioactive material also play a large role in generating the heat inside the Earth.

Answer 6

The magma rise from the earth because the density of the hot magma that causes it to rise past the denser cool magma. The magma then stops when it reaches the ocean floor

Answer 7

god put it there

Answer 8

No.
