What causes the inner core to be solid when the outer core is liquid?
The extremely high pressure at the inner core drives the melting point of the iron and other materials up beyond the temperature of the inner core. Therefore they remain solid. The pressure in the outer core is lower sop the melting point is below the temperature in this region and so it is a liquid.
Why is the inner the outer core liquid?
The inner core of the Earth is solid due to high pressure preventing melting, while the outer core is liquid because it is under less pressure. The outer core is also hotter, allowing it to remain in a liquid state.
How are inner core and outer core different?
The inner core is solid due to high pressure and temperature, while the outer core is liquid. The inner core is composed mainly of solid iron and nickel, while the outer core is also made of iron and nickel but in a liquid state.
Where can the center of the Earth be locate?
The center of the Earth can be located at a point beneath the surface, approximately 6,371 kilometers (3,959 miles) from the Earth's outer surface. This point is at the core of the Earth, which is composed of a solid inner core and a liquid outer core.
What keeps earth inner core from melting?
The inner core of the Earth is kept from melting by the immense pressure exerted on it by the overlying layers of the Earth, such as the outer core and mantle. This pressure raises the melting point of the iron and nickel present in the inner core, preventing them from melting despite the high temperatures. Additionally, the inner core's solid state is also maintained by the heat generated by radioactive decay within the Earth.
Is the temperature of the outer core higher or lower than ist melting point?
The temperature of the outer core is higher than its melting point. The outer core is mainly composed of liquid iron and nickel, which has a melting point higher than the temperature of the outer core due to the immense pressure at that depth.
Is the temperature of the outer core higher or lower then the melting point?
higher
Is the temperature of the outer core higher OR lower than its melting point?
The outer core is liquid. Its pressure is low enough and its temperature high enough for it to melt. The inner core is solid. Both its pressure and temperature are higher than the outer core, but the increased pressure overwhelms the increased temperature, keeping the inner core from melting.
What keep the iron from melting in the core?

What keep the iron melting in the core?

The pressure in the outer core is lower sop the melting point is below the temperature in this region and so it is a liquid.
What prevents the outer core from changing to a gas or the inner core from melting to a liquid?
The immense pressure on the core raises melting and boiling points of the metal, allowing the outer core to reman liquid and the inner core to remain solid.
In earths interior which zone has temperature higher than its melting point?
outer core; Earth Science Reference Tables page 10
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 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.
Is the moon solid?
This phenomenon has to do with melting temperature and pressure. The more pressure a substance is under, the higher its melting point becomes. Both the liquid outer core and the solid inner core are made of an iron alloy, which means that chemically their melting points are the same. However, the outer core is under less pressure simply because it is under less material. The outer core supports the weight of the crust and mantle, while the inner core must also bear the weight of the outer core. The additional mass of the outer core creates enough pressure on the inner core to raise the melting temperature of the iron alloy above the temperature at the center of the earth, causing it to solidify. So in short, the inner core is solid because it is under more pressure than the outer core. Hope this helps
