What does the theory of plate tectonics state about the earth's surface? A. one solid piece
B. very thick compared to the mantle
C. mostly covered in water
D. broken into many pieces

Answer : D

During an earthquake, the tectonic plates are broken into many pieces

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.
