Study the image, which shows an air mass moving into a region. An area of warm, moist air is moving inland over the United States.

What type of weather will this region most likely experience due to the incoming air mass?

thick fog with cold air
sunny skies with warm air
thunderstorms and heavy rain
cooler temperatures with no rain

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.
