Study Notes
Earth's Magnetic Field
- The primary reason for Earth having a magnetic field is the motion of molten iron in the Earth's outer core.
Protection of the Planet
- The Earth's magnetic field contributes to protecting the planet by deflecting charged particles from the sun, known as the solar wind, which would otherwise strip away the atmosphere.
Consequences of No Magnetic Field
- If Earth did not have a magnetic field, the planet's atmosphere would be stripped away by the solar wind, leading to a loss of atmospheric gases and making the planet uninhabitable for life.
