Look at the section of tectonic map. describe what is happening at the plate boundary. missing metadata a. the seafloor is spreading. b. an oceanic plate is subducting. c. two continental plates are colliding. d. two plates are sliding past each other.

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.
