Actually it's not.
As best as we can tell the center (a ball of nickel/iron slightly smaller than the moon) is solid. The layer outside it is liquid.
The liquid part is liquid because it's hot (part gravity, part radioactive decay)
The solid part is also hot, but the pressure is great enough to solidify it.
