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.

“One of the important things to learn about parenting is that the more you worry about a child, the less the child will worry about him- or herself....instead of worrying, watch with fascination and wonder as your child’s life unfolds, and help the child take responsibility for his or her own life.”
—Charlotte Davis Kasl (20th century)
