Why is the inner core of the earth solid and the outer core molten?

It's actually due to the pressure inside of the earth. After acertainpoint ofpressurethe iron and nickel that makes up the inner core can no longer become liquid even though the heat produced is well above the melting point for iron.

Earth's solid inner layer is surrounded by the hot molten metal of which layer?
outer core
Is the inner part of the Earth melted rock?
No the inner part is a dense solid sphere of iron and nickel. The outer core however, is molten metal.
What materials make up the inner core?
The inner core of the Earth is composed of solid iron. The outer core is made up of molten metals, primarily a nickel-iron alloy.
What explains why the earth has a magnetic field?
The Earth's inner core consists of solid nickel and iron and the outer core consists of molten nickel and iron. Bother metals are magnetic.

outer core
What the central part of earth that consists of and inner and outer portion?
core: inner solid, outer molten. the mantle is also sometimes divided into lower & upper.
Is the inner core molten?
The inner core is solid due to pressure. With less pressure on it, the outer core is liquid.
How is the inner core and the outer core of the earth similar?
They are both made of iron and nickel. The only difference is that the outer core is molten whie the inner core is solid.
Which layer of the earth is completely solid?
the earth's inner core is solid, and the crust is solid, obviously, because we can walk on it.
Is the inner part of the Earth melted rock?
No the inner part is a dense solid sphere of iron and nickel. The outer core however, is molten metal.
The center part of earth is made up of two parts the molten outer core and the what?
solid metal inner core
What part of the earth has the crust mantle inner an outer part?
The earth is made up of 4 layers. The inner core in the center, surrounded by the outer core. The inner core is solid and still. The outer core is molten metals and moves around the inner core contributing to earth's magnetic field. After the inner core and outer core comes the mantel and then the earth's crust. The crust makes up the surface of the earth.
What material makes up earth's inner core outer core and mantle?
the inner core is made up of solid iron, the outer core is made out of molten metal, and the mantle is made up of solid it feels like Jello.
What is the core mostly made of molten metal or solid metal?
It is widely scientifically believed that the inner core (deepest part of Earth) is made of solid iron. However the inner core is surrounded by an outer core of iron and nickel that is believed to be molten material.
