About _?_ percent of the solar energy that reaches the outer atmosphere is absorbed at the earth’s surface a - 20
b - 30
c - 50
d - 70

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.

The answer is energy. the arrows are showing how exited and energized the stones are.
