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.
Geologists also can learn a lot about the core of our planet by looking at Earthâs magnetic field. The Magnetic field is created by massive circulations of hot liquid mantle beneath the Earthâs surface. These clues lead geologists to believe that the Earth is made of four distinct layers. These layers are the crust, the mantle, the outer core, and the inner core.
