What does it mean if a galaxy gives off light that has been shifted toward the red end of the electromagnetic spectrum? A The galaxy is much older than Earth. B The galaxy is moving away from Earth. C The galaxy is very hot and has not cooled down yet. D The remnants of an explosion are between the galaxy and Earth.

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.
