There are currently only 13 members of the Senate who served in the military. In all, 97 members of the next session of Congress will have served in the U.S. military. That means less than 18 percent of the new congressional delegation served in the armed forces.
the layer of the earth resposible for the earths magnetic field is the core which consists of the liquid core/outer core and the solid core/inner core.
Because of this, we are well protected from the electromagnetic radiation of space weather. The Earth's main protection against energetic particles, which can be just as harmful as electromagnetic radiation, is its magnetic field and the protective effects it creates. The Earth's magnetic field creates a shield which deflects ionised particles so that they cannot reach the Earth's surface.
