In Maine, vision testing is required at the first renewal after driver's 40th birthday, then at every second renewal until age 62, and thereafter at every renewal. In Oregon, vision testing is required every 8 years for drivers 50 and older. In Illinois and New Hampshire, applicants 75 and older must take a road test.
Bottom line: When charged particles from the sun strike atoms in Earthâs atmosphere, they cause electrons in the atoms to move to a higher-energy state. When the electrons drop back to a lower energy state, they release a photon: light. This process creates the beautiful aurora, or northern lights.
The northern lights are light you can see in the sky. They are created be solar storms. The storms hit the atmosphere and are forced to the poles. The storms mix with oxygen a â¦ nd tern into colours and that is what you see.
