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:
“Where there is not discernment, the behavior even of the purest soul may in effect amount to coarseness.”
—Henry David Thoreau (1817–1862)
“Make me thy Loome: thy Grace the warfe therein,
My duties Woofe, and let thy word winde Quills.
The shuttle shoot. Cut off the ends my sins.
Thy Ordinances make my fulling mills,
My Life thy Web: and cloath me all my dayes
With this Gold-web of Glory to thy praise.”
—Edward Taylor (1645–1729)
