The islands of Polynesia are emerged underwater volcanoes of the Hawaiian type, which erupted from a north-south dorsal that extends to the north-west according to the drifting movement of the oceanic floor, called plate tectonics. The volcanoes correspond to the "hot spots" of the floor, from which the deep magma spouted. Taking into account the incessant drift of this floor, the islands born at these hot spots drift progressively westward (10 cm per year), while the hot spots continue to spew forth magma, creating a new volcano, etc. As these islands drift westward, they sink into the oceanic floor under their own weight (which is called subsidence), and the coral that had colonized their shores remains on the reef base that it has created. Thus, the island is diminished in size and height and the space left between the original reef and the new shores is then filled in by a lagoon, which enlarges as the island shrinks. During the final stage the island totally disappears under the water's surface, and there remains only a central lagoon and the reef crown, which is then an atoll. We can then say that the high islands, without lagoon nor crown reef (the Marquesas) are the youngest, and those that have a vast lagoon are the oldest (the Society Islands), and in between are the atolls. The maritime space occupied by French Polynesia extends over 5,500,000 square kilometers (counting the territorial waters), and if we superimpose a map of the territory over a map of Europe, we can see that the five archipelagoes are dispersed over a distance equaling that from Brest to Bucarest and from Stockholm to Rabat. The combined land surface of these 118 islands is only 4,000 square kilometers, a mere speck of dust scattered on the immense ocean.
