Is everything that the sun
sends to Earth good?
• Nope!
• The Sun emits or sends harmful
radiation particles that would be bad for
all living things on earth.
• Radiation is the transfer of energy
through space by electromagnetic
waves
• High energy particle radiation that could
endanger life on Earth is forced to drift
around the Earth within two large donutshaped regions called radiation belts.
Invisible magnetic fields are the reason that
particle radiation moves in this way.
• The magnetic fields repel the particles
