Great question. It may seem strange because you may think that the inner core really should be liquid as it is the hottest layer of the Earth. However it is also under a very high pressure, and as the pressure on a material increases so too does it's melting temperature. The reason for this is that iron requires an increase in volume to change from the solid to the liquid state and the higher the pressure exerted on a material the more energy (in the form of heat) is required to overcome this confining pressure. In the case of the iron at the core, the temperature is not high enough to overcome the confining pressure that is exerted and so the materials melting temperature is driven up beyond that which actually occurs within the inner core.

Is the core liquid or solid?
There are two parts of the core: Inner and Outer. The outer core is liquid, the inner solid. The inner core is solid due to the pressure exerted on it, despite the excessively high temperature.
Is the inner core or the outer core solid?
In inner core is solid while the outer core is liquid. This is because the inner core, being deeper, is under more pressure.
Which layer of the earth is made up of solid nickel and iron?
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.
Why is the inner the outer core liquid?
the inner core is solid because of tremendous pressure the outer core is liquid due to less pressure and heat
Is the inner core molten?
The inner core is solid due to pressure. With less pressure on it, the outer core is liquid.
Are the inner and outer core of earth the same?
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.
Is the inner and outer core together solid and liquid?
Well, the outer core is made of liquid and the inner core is solid so i guess in a way it kind of is solid and liquid.
Is the solid outer core more dense than the liquid inner core?
This question is based on a false assumption that the outer core is solid and the inner core is liquid. This is incorrect. It is in fact the inner core that is solid (and so is the most dense) and the outer core which is liquid.
Is the core liquid or solid?
There are two parts of the core: Inner and Outer. The outer core is liquid, the inner solid. The inner core is solid due to the pressure exerted on it, despite the excessively high temperature.
What is the differences between the inner core and the outer core?
The inner core is a solid, and the outer core is a liquid.
How does outer core different from inner core?
outer core is liquid whereas the inner core is solid
How does the outer core differ from inner core?
outer core is liquid whereas the inner core is solid
How did the outer core become solid?
It isn't. The inner core is solid, the outer core is liquid.
What difference between inner core and outer core of earth?
The inner core Is solid and the outer core in liquid
What is Difference between earths inner core and outer core?
The inner core Is solid and the outer core in liquid
Is the earth's core liquid or solid?
Both! The outer core is in a liquid state and the inner core is a solid. Both the inner and outer core are formed mainly of iron and nickel.
Is earths core liquid or solid?
Both! The outer core is in a liquid state and the inner core is a solid. Both the inner and outer core are formed mainly of iron and nickel.
