EARTH CREATES A MAGNETIC FIELD FROM THE HEAT OF THE INNER CORE.
WE HAVE POLAR NORTH AND SOUTH; LIKE A MAGNET. THE MAGNETIC FIELD EXTENDS BEYOND THE ATMOSPHERE. IT PROTECTS BOTH THE ATMOSPHERE AND THE EARTH. WITHOUT IT, EARTH WOULD BE MORE LIKE MARS. EARTH'S MAGNETIC FIELD DEFLECTS MOST OF THE SOLAR WIND: PROTECTING THE OZONE LAYER THAT PROTECTS THE EARTH FROM HARMFUL ULTRAVIOLET RADIATION. SCAVENGING IONS FROM SOLAR WINDS CREATED A LOSS OF CARBON DIOXIDE FROM MARS' ATMOSPHERE: WHICH ALMOST COMPLETELY RUINED THE ATMOSPHERE OF MARS.
