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.
How are inner core and outer core different?
The inner and outer core are different because of the difference in vertical stress within the Earth. As the confining pressure increases it drives up the melting temperature of materials (in this case iron and nickel). The boundary between the outer and inner core marks the point where the confining pressure is so high that it drives the melting temperature of the core material above the temperature within the core. As such it is no longer hot enough to melt the iron / nickel mixture and it solidifies.
What would happen if there was less pressure on the earths inner core?
The melting temperature would drop. If it dropped to a point below the in-situ temperature, melting of the inner core would occur.
Is the inner core outer core mantle or crust have liquid?
outer core
What type of rock is found in the outer core?
There is no rock in the outer core. The outer core is liquid iron-nickel.
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 melting in the core?
I think the outer core

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.
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?
Although the tempreture of inner core is more then the melting point of the material that makes it up is in solid state because of high pressure exearted by the outer core and earth crust.
In earths interior which zone has temperature higher than its melting point?
outer core; Earth Science Reference Tables page 10
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
