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:
“We all have—to put it as nicely as I can—our lower centres and our higher centres. Our lower centres act: they act with terrible power that sometimes destroys us; but they don’t talk.... Since the war the lower centres have become vocal. And the effect is that of an earthquake. For they speak truths that have never been spoken before—truths that the makers of our domestic institutions have tried to ignore.”
—George Bernard Shaw (1856–1950)
“Not lived; for life doth her great actions spell,
By what was done and wrought
In season, and so brought
To light: her measures are, how well
Each syllab’e answered, and was formed how fair;
These make the lines of life, and that’s her air.”
—Ben Jonson (1572–1637)
