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.
So far as science can deduce, it must be a solid.
It is solid because there is so much pressure that it makes it really dense.
1. we would never be able to get down to the bottom to the core because we dont have the machineary and if we got past the earths crust hot molten lava would pour out and destroy the country. 2. if we mined the earths core it would be so hot no thing could survive it and we couldn't mine it because it is extremely hard
The Earth has an iron core. At the outer core it is so hot that the iron is liquid. At the inner core it is hotter still, but under so much pressure it forces the iron to solidify. Hence: the Earth's core.
it is made of liquid and the liquid is most likely made of iron aka (liquid iron) The outer core is composed of liquid iron and nickel mainly. So is the inner core, but it is solid.
no the core of the earth is not solid its pretty much a liquid, since the middle of the earth is so hot, the core is like a lava substance.
So far as science can deduce, it must be a solid.
iron and nickel is the answer and so is the inner core. the inner and the outer and together but the outer core is liquid and the inner core is solid
First: The earths core is not molten, it is a very dense solid mass, kept solid by the intense pressure on it. Second: It is the layer around this core that is molten, and yes it does influence gravity, but more so earths magnetism.
yes its extremely hot and so high pressured that it is a solid.
yes its extremely hot and so high pressured that it is a solid.
The higher the pressure, the more likely a liquid will turn into a solid. So, high pressure (like the Earth's core) can turn a core solid.
cool stuff
It is solid because there is so much pressure that it makes it really dense.
the 2 main variables which decide whether an element or compound is a solid, liquid, or gas, are temperature and pressure.Iron melts at 1538 degrees only when it is pure (which the core is not) and under atmospheric pressure. The iron in the earths inner core is under pressure equivalent to many thousands (if not millions) times that of atmospheric pressure, so it exists as a solid.

Melted iron and nickel alloy. It is too hot near the centre, so it is liquid. But if you want to know if the inner core is solid or liquid, then it is solid, because there is too much pressure from the rest of the Earth
