Final answer:
Portugal is the country that has the Azores and Madeira as autonomous regions, where the Azores consist of 9 volcanic islands in the North Atlantic.
Step-by-step explanation:
The country that has the Azores and Madeira as autonomous regions is Portugal. The Azores are an archipelago of 9 volcanic islands situated in the middle of the North Atlantic Ocean over the Mid Atlantic Ridge, renowned for their temperate climate and being affected by the Gulf Stream.
The Madeira archipelago, similarly, is an autonomous region of Portugal and is rich in historical significance as it, along with the Azores, were important stepping stones in the expansion of Portuguese maritime exploration and colonization efforts.
This expansion included the islands south of the Canaries and was influenced by the Pope's decree in 1481 and led to Portugal's navigation down Africa's western coast and over to Brazil, shaping the Portuguese Atlantic Empire.
