Effect On Life
Without the outer core, life on Earth would be very different. Convection of liquid metals in the outer core creates the Earth's magnetic field. This magnetic field extends outward from the Earth for several thousand kilometers, and creates a protective bubble around the Earth that deflects the solar wind. Without this field, a larger proportion of the solar wind would directly strike the Earth's atmosphere. The presumed effect would be to strip the Earth's atmosphere away slowly. This is hypothesized to have happened to the Martian atmosphere, rendering the planet effectively lifeless.

So those who enter death must go as little children sent.
Nothing is known. But I believe that God is overhead;
And as life is to the living, so death is to the dead.”
