See § Data values
Air is the block present in otherwise empty space.
Void air[Java Edition only] is used internally for blocks above (Y>255) and below (Y<0) the world, and in unloaded chunks.
Air can be selected in the creation of worlds tab in Legacy Console Edition.
Structures above ground generate normal air (with the exception of exposed badlands abandoned mineshafts and surface ponds, which generate cave air), and underground structures generate cave air. Void air is used in place of unloaded chunks and above or below the world's buildable area.
