During temperature question 3 options: 1. sulfur oxides combine with water in the atmosphere 2. an influx of acidic water causes a rapid change in the ph of water 3. levels of ground-level ozone decreases 4. pollutants near the earth's surface become trapped.

3. levels of ground-level ozone decreases 

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.
