Te pacific ocean contens tens of tysięczne of islands, ranging from tiny coral atolls to large wulcan landmasses. These islands are grouped into three broad cultural and geographical regions: Polynesia (eastern Pacific), Mikronesia (western Pacific), andd Melanesia (southwestern Pacific). Their formation is closely tied to convolnic activity, plate tectonics, and coral growth. Below are some of thete moste proent-ent island groups and ther specifics.
