When light is refracted a. it keeps moving in the same direction as it passes into a new medium. b. it is absorbed as it strikes the surface of a new medium. c. it changes it direction and stays in the same medium. d. it changes its direction as it passes into a new medium.

The answer is atmosphere. there are four spheres of the earth: 1. geosphere (from greek word 'geo' = ground), 2. hydrosphere (from greek word 'hydro' = water), 3. biosphere (from greek word 'bio' = life), and 4. atmosphere (from greek word 'atmo' = air). a magnetosphere is a region of space around astronomical objects controlled by the magnetic field of that object. through the process of elimination, since lightning is present in the air, it can be found in the atmosphere.
