How the ionized layer protects us from radiation. The ionized solar winds are separated by the magnetic field. The bata particles are attracted to the north pole which makes it negative.The alpha particles are attracted to the south pole and that makes it positive. This creates a high current that flows in the upper atmosphere and is what makes the Van Allan belt. U cant do anything to change the flow of the solar winds,and u cant change the magnetic field. If the ozone layer gets thin then a special thing happens ,the alpha particles start hi ting nitrogen in the area and trans mutates nitrogen to oxygen.
Isn't that neat
