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 earth's inner core in a solid state when it's temperature is above the melting point of material that makes it up?
The inner core of the Earth is solid due to the immense pressure from the layers above it. This pressure prevents the materials from melting even though the temperature is above the melting point. The combination of high pressure and high temperature keeps the inner core in a solid state.
Why is the Earth's core solid if it's so hot?
The earth's core isn't entirely solid. In fact the earth's core is slit into two main sections. The inner core (which is solid) and the outer core which is liquid. This is because the melting point of materials varies depending on the applied pressure. As pressure increases so to 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.
How are the outer core and inner core diffrint?
The outer core is in a liquid state, primarily composed of molten iron and nickel, while the inner core is solid due to higher pressure even though it is composed mostly of iron and nickel as well. The outer core is responsible for generating the Earth's magnetic field through convection currents, while the inner core contributes to the Earth's overall structure and composition.
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 state of mater in the inner core?
The state of matter in the inner core of the Earth is believed to be solid, mainly composed of iron and nickel. The immense pressure at the Earth's core keeps these materials in a solid state even at extremely high temperatures.
What is the two difference between the inner core and the outer core of earth?
The inner core of the Earth is solid due to intense pressure, while the outer core is liquid because it is at a slightly lower pressure. Additionally, the inner core is composed mainly of solid iron and nickel, whereas the outer core is a mix of liquid iron and nickel.
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.
What part of earth has the greatest density?
The Earth's core has the greatest density. The inner core, composed mainly of solid iron and nickel, is even denser than the outer core, making it the densest part of the Earth.
The inner core solid liquid or gas what keeps it in this phase?
The inner core of the Earth is solid due to high pressure pushing in on it from all directions, which prevents it from melting even though it is extremely hot. The heat generated by the decay of radioactive elements also helps maintain the inner core's solid state.
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.
Why the inner core solid despite its extremely high temperature?
The inner core is solid due to the extreme pressure at its center, which compresses the iron and nickel into a solid state even at high temperatures. The inner core's solid nature allows it to maintain its structure and resist the extreme temperatures present in the Earth's core.
Why is the earth's inner core in a solid state when it's temperature is above the melting point of material that makes it up?
The inner core of the Earth is solid due to the immense pressure from the layers above it. This pressure prevents the materials from melting even though the temperature is above the melting point. The combination of high pressure and high temperature keeps the inner core in a solid state.
What are the physical properties of the inner core?
The inner core of the Earth is solid due to high pressure, even though it is made up primarily of iron and nickel. It has a temperature of about 5700 degrees Celsius, making it the hottest part of the Earth.
