The inner core of the Earth, its innermost hottest part as detected by seismological studies, is a primarily solid ballabout 1,220 km (760 mi) in radius, or about 70% that of the Moon. It is believed to consist of an iron-nickel alloy, and may have a temperature similar to the Sun's surface, approximately 5700 K (5430 °C).

∙ 12y agoAs we go inside the Earth, the temperature increases, but so does the confining pressure. As the pressure increases, the melting point of the materials increases as they become harder and denser. The outer core is liquid due to the fact the melting point hasnt increased above its temperature. At the boundary of outer and inner core, the pressure becomes high enough to raise the melting point of the materials above their temperature. So it is solid
The inner core is solid because the main constituent of inner core is iron. In the inner core the pressure is nearly 330-360 giga pascal and temperature is nearly 5900K. at these pressure the melting point of iron increases upto an extent that it can be in solid state even at that high temperatures. Hence, the inner core of earth is in solid state.

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.
Solid part of core of earth?
The inner core is the solid part
Is the inner core molten?
The inner core is solid due to pressure. With less pressure on it, the outer core is liquid.
Which layer of earth is made of extremely dense solid metal?
The inner core of the Earth is believed to be solid and composed mainly of iron. The 4 layers of the Earth include the crust, the mantle, and the inner and outer cores.
Inner core state of matter?
the inner core is a solid
Is the inner core a liquid a solid or a gas?
the inner core is mainly made as a solid. its like the rest besides outer core.
Is the inner core made of solid liquid or gas?
The inner core is solid.
Is the inner core a solid liquid or plastic like?
The inner core is solid
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 a liquid or solid?
inner core of what? the earth's inner core is in solid form if that's what you mean.
Which core of earth is solid?
The inner core is solid.
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.
Is the inner core mostly a liquid or solid?
The inner core is currently thought to be entirely solid.
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.
Solid part of core of earth?
The inner core is the solid part
What is inner core made up of?
The inner core is made out of iron and nickel and it is a solid.
