text: As shown in the temperature diagram and in the wave-velocity diagram, the outer core of the Earth must be a liquid, or given the materials and temperatures involved, a molten material (molten meaning a liquid form of a normally solid material that requires very high temperatures to melt); and the molten outer core of the Earth cannot be made of exactly the same materials as the solid inner core, because the temperature of the Earth must be higher the further down you go (heat only goes from hot places to cold places, and since it comes from inside the Earth and escapes at the surface, the temperature of necessity must increase all the way down, regardless of any details that we wouldn't want to consider in an introductory discussion and although there is a lot covered here, so it may seem complicated, this is actually a very simple discussion compared to what a student majoring in astronomy, geology, planetary geology or geophysics would encounter).
text: Cores of specific planets may be entirely solid or entirely liquid, or may be a mixture of solid and liquid layers as is the case in the Earth.
text: The model further concludes that the core of mars is entirely liquid, as the latent heat of crystallization would have driven a longer-lasting (greater than one billion years) dynamo.
text: If the core of Mars is liquid, the lower bound for sulfur would be five weight %.
text: However, within the past decade much data has been gathered to indicate that the core is at least partially liquid.
text: Like that of Earth, the Venusian core is at least partially liquid because the two planets have been cooling at about the same rate.
text: It should be noted that it is often incorrectly stated in public media that the inner core is solid, while the outer core is liquid, because of the much greater weight compressing the inner core.
text: Existence of a relatively strong magnetic field and the behavior of seismic waves as they pass through the interior of the Earth implies that the core is liquid with perhaps a solid Fe-Ni central region
