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:
“A readiness to believe ill of others, before we have duly examined it, is the effect of laziness and pride. We are eager to find a culprit, and loath to give ourselves the trouble of examining the crime.”
—François, Duc De La Rochefoucauld (1613–1680)
“Young, and so thin, and so straight.
So straight! as if nothing could ever bend her.
But poor men would bend her, and doing things with poor men,
Being much in bed, and babies would bend her over,
And the rest of things in life that were for poor women,
Coming to them grinning and pretty with intent to bend and to kill.”
—Gwendolyn Brooks (b. 1917)
