At some point of depth in the Earth's interior, around 5150 km, is the transition from the liquid outer core and the solid sphere of the inner core, a ball of incredibly hot iron-nickel alloy. Temperatures here reach between 5,000 and 7,000 degrees C, and pressures are calculated to be around 3,000,000 units of sea level atmospheric pressure. Despite the high temperature, at these pressures the metals cannot remain molten.

What is inner core made up of?
The inner core is made out of iron and nickel and it is a solid.
Why is earths inner core solid?
Earth's core is a solid made up of mainly iron and other metals. Even though temperatures here reach sometimes 5000-7000 degree Celsius but pressure is extremely high. Due to this high pressure, the metals remain solid even though temperatures exceed their melting points.
Why is the inner core of the earth solid and the outer core molten?
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.
What happens to the temperature and pressure as you get closer the the earth's core?
Temperature and pressure increase massively from the Earth's surface to the centre of the Earth. At the inner core, the pressure is so great that iron is solid, even at such high temperatures.
Why is iron core of the earth solid?
The iron core of the earth is solid because the immense pressure near the center of the earth, due to gravity, keeps the iron in a solid state, even though it is hot.
What are the effects of the inner core?
The inner core is solid, even though it has a high temperature, because of the high pressure in the center of Earth.
What is the two difference between the inner core and the outer core of earth?
the two difference are that the inner core is solid and even though its very hot. the outer core are high temperatures
Why is the Earth's innermost layer a solid?
The immense pressure inside Earth keeps the inner core solid even though it is well above its normal melting temperature.
What is inner core made up of?
The inner core is made out of iron and nickel and it is a solid.

Why inner core is solid?
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).
What is the Phase of matter of inner core?
The inner core of the Earth is made of solid nickel and iron, but mostly nickel. Wouldn't you think it was a liquid, or even a gas, because it's so extremely hot in the core? Actually, it's solid because there's so much pressure on it from the rest of the Earth and the atmosphere. Talk about having the "weight of the world on you". ;)
What happens to the temperature and pressure as you get closer the the earth's core?
Temperature and pressure increase massively from the Earth's surface to the centre of the Earth. At the inner core, the pressure is so great that iron is solid, even at such high temperatures.
Why is the inner corre solid the outer core liquid?
The inner core is solid due to the high pressure. Even at such a temperature, the pressure is so great that the material can only exist as a solid. The outer core is liquid as it is at a huge temperature, yet does not have the pressure to force it into solid form.
Why is the core solid?
As 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.
What is the movement of the inner core?
it is under so much pressure form the rest of the earth it behaves like a solid.
