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.

Is the core of the earth molten?

Part of it is. The outer core is molten while the inner core is solid.


Is the inner core molten?

The inner core is solid due to pressure. With less pressure on it, the outer core is liquid.


Does the earth have large molten core?

Yes, the Earth has a large molten core composed mostly of iron and nickel. The outer core is liquid, while the inner core is solid due to high pressure. This molten core generates the planet's magnetic field.


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 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 is a layer of molten iron and nickel that surrounds the inner core of earth?

The layer you are referring to is the outer core. It is a liquid layer made up of molten iron and nickel that surrounds the solid inner core of the Earth. The movement of this molten outer core is believed to generate Earth's magnetic field.


Earth's solid inner layer is surrounded by the hot molten metal of which layer?

The Earth's solid inner layer is surrounded by the hot molten metal of the outer core. This outer core is composed mostly of iron and nickel, and its high temperatures and pressure give it the ability to flow in a liquid state.


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 outer core made of solid metal?

The Earth's inner core is solid metals and the outer core is liquid metals.


What is the relationship between Earth's inner core and outer core?

The Earth's inner core is a solid ball of iron and nickel at the center of the planet, while the outer core is a layer of molten iron and nickel surrounding the inner core. The inner core is believed to be solid due to high pressure, while the outer core is liquid due to lower pressure and higher temperatures. The movement of the molten outer core is thought to generate Earth's magnetic field.


What layer of the earth is made of molten iron and nickel that surrounds the inner core?

The outer core of the Earth is made of molten iron and nickel. It lies beneath the mantle and surrounds the solid inner core. This molten layer is responsible for generating the Earth's magnetic field through convection currents.
