The outer core is not solid, it is liquid.
There are two parts of the core: Inner and Outer. The outer core is liquid, the inner solid. The inner core is solid due to the pressure exerted on it, despite the excessively high temperature.
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.
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.
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.
Solid due to the extremely high pressure caused by the overlying layers of liquid outer core and solid mantle. This pressure prevents the inner core from melting despite its high temperature.
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.
The inner core of the Earth is believed to be solid due to high pressure and temperature conditions. It is composed mainly of solid iron and nickel, while the outer core is in a liquid state.
The Earth's core is primarily composed of iron and nickel. The outer core is in a liquid state due to the high temperatures and pressures, while the inner core is solid due to the extreme pressure despite the high temperature.
The Inner Core is the most dense part of the Earth. It is a solid core of iron and nickel.
In inner core is solid while the outer core is liquid. This is because the inner core, being deeper, is under more pressure.
Both the inner and outer core are made mostly of iron and nickel. The outer core is liquid while the inner core is solid.
The inner core is solid due to high pressure preventing the temperature from melting the iron-nickel alloy. The outer core is liquid because the lower pressure allows for the metal to remain in a molten state.
