On FAR AIM, definition of warning area is
Airspace of defined dimensions, extending from three nautical miles outward from the coast of the U.S, that contains activity that may be hazardous to nonparticipating aircraft
And on Wikipedia, definition of ADIZ is
Airspace over land or water in which the identification, location, and control of civil aircraft is performed in the interest of national security.
I was confused because the definition of these two airspace is similar with each other. And I thought that those area could be overlapped with each other. Could anyone explain the difference, or at least an example chart that contains this two areas?
And if an aircraft tried to fly to the U.S territory from the sea, which area does the aircraft encounter first : 'warning area' or 'ADIZ'?
