If the earth were not tilted on its axis, what would be the result? a) day length would be less than 24 hours. b) both sides of the moon would be visible. c) temperatures would be constant year round. d) the length of the year would be more than 365 days.

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.
