The inner core is composed of an iron and nickel alloy (mixture) along with some other minor elements. The inner core of the earth is a (rather) solid metal core made up of nickel and iron which has a diameter of 2440 km. The outer has a similar composition and temperature, but is under less pressure and remains in a liquid state.
The Earth's core is not made up of magma and lava which are molten minerals (liquid rock).
The existence of an inner core distinct from the liquid outer core was discovered in 1936 by seismologist Inge Lehmann using observations of earthquake-generated seismic waves that partly reflect from its boundary and can be detected by sensitive seismographs on the Earth's surface.

The outer portion of the core is mostly molten iron. The inner core is solid metal.
What is the inner core layer of the earth?
The Inner core is the very center of Earth. It's 760 mi. in radius. It's composed of solid Iron and Nickel (i think), and has a temperature similar to the surface of the sun (5430 °C).
What is made of solid iron and nickel spins to produce earths magnetic field?
Earth's outer core (as opposed to the inner core).
How thick is earths inner core?
The inner core is 1216 km and made of solid iron. It is approx 5000 degrees C and it doesnt melt because of everything else pushing down on it.
How would you describe the earth's core?
The Earths Core can be broken into two pieces the inner core and the outer core. The Inner Coreis made of SolidIron. The Outer Core is made of Liquid Iron.

What is a facts about the inner core?
the inner core is NOT made from rock.?!
What dense center of earth is made of solid iron and nickel?
There are two parts to core at the center of the Earth.the outer core is made of liquid iron and nickel and the inner core is made of solid iron and nickel.The inner core is solid from all off the pressure pushing down on it.
What are the 2 different layers of the core?
The inner core and the outer core. The outer core is made of molten metal and the inner core is made of solid metal.
