The inner core is an alloy of iron and nickel, and the outer core is mainly liquid iron and nickel.The liquid layer made up of hot liquid iron and nickel that surrounds the inner core.
high pressure
In general the inner part of the core of something. The core of the Earth is made mostly of iron and some nickel. The outer part of the core is liquid, the inner core is under such high pressure that it is solid.
Inner core
The outer core is liquid, the inner core is solid The outer core surrounds the inner core The outer core is iron-rich, the inner core is iron-rich and nickel-rich There is more pressure acting on the inner core The inner core is hotter

Inner core
The earth's inner core is solid composed of nickel iron alloy. It is solid despite the very high temperature because of the very high pressure.

The solid nature of the inner core has to do with temperature and pressure. The inside of the earthâ??s core is much hotter than the liquid that is outside the core. Typically, solids tend to be much more dense than liquids because they are packed more tightly.
The melting point of materials varies depending on the applied pressure. As pressure increases so does the melting temperature. This relationship is normally shown in a phase diagram.The main constituent of the inner core is iron and the inner core pressure is approximately 330-360 GPA while the temperature varies from approximately 5000 to 7000 K.The extremely high pressures in the Earth's inner core therefore drive the melting point of the iron up beyond the temperature that occurs and the metals of the inner core cannot melt.As such the inner core is solid, even though it is the highest temperature region in the Earth.Please see the related links.
The inner core
The inner core.
No. The inner and outer core are both composed primarily of iron and nickel, but the outer core is liquid and surrounds the inner core. The inner core is the innermost layer of Earth and is kept solid by the enormous pressure.
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.
