Outer Core - Effect On Life

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.

Famous quotes containing the words effect and/or life:

    I guess what I’ve really discovered is the humanizing effect of children in my life—stretching me, humbling me. Maybe my thighs aren’t as thin as they used to be. Maybe my getaways aren’t as glamorous. Still I like the woman that motherhood has helped me to become.
    Susan Lapinski (20th century)

    Society is the stage on which manners are shown; novels are the literature. Novels are the journal or record of manners; and the new importance of these books derives from the fact, that the novelist begins to penetrate the surface, and treat this part of life more worthily.
    Ralph Waldo Emerson (1803–1882)
