Adrainage basin is the area of land where surface water is drained downhill into a body of water. a divide is a. a man-made fence that is built at the top of a drainage basin. b. a line halfway down the slope of a drainage basin. c. the low ground where two drainage basins meet. d. the high ground separating two drainage basins.

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.
