Micronesia - online puzzles

Micronesia ((UK:, US: ); from Greek : μικρός mikrós "small" and Greek : νῆσος nêsos " island ") is a subregion of Oceania, composed of thousands of small islands in the western Pacific Ocean. It has a close shared cultural history with two other island regions : Polynesia to the east and Island Melanesia to the south ; as well as with the wider Austronesian peoples.

The region has a tropical marine climate and is part of the Oceania ecozone. There are four main archipelagos—the Caroline Islands, the Gilbert Islands, the Mariana Islands, and the Marshall Islands—along with numerous outlying islands.

Politically, the islands of Micronesia are divided between six sovereign nations: the Caroline Islands are divided between the Republic of Palau and the Federated States of Micronesia, the latter often shortened to "FSM" or "Micronesia" and not to be confused with the overall region ; the Gilbert Islands (along with the Phoenix Islands and Line Islands in Polynesia ) comprise the Republic of Kiribati; the Mariana Islands are in union with the United States, divided between the U.S. Territory of Guam and the U.S. Commonwealth of the Northern Mariana Islands ; Nauru is a fully sovereign nation, coextensive with the island of the same name ; and the Republic of the Marshall Islands is coextensive with that island group. Also noteworthy is Wake Island, which is claimed by both the Republic of the Marshall Islands and the United States, the latter having actual possession under immediate administration of the United States Air Force.

Human settlement of Micronesia began several millennia ago. There are competing theories about the origin(s) and arrival of the first Micronesians. The earliest known contact with Europeans occurred in 1521, when Spanish ships landed in the Marianas. The term "Micronesia" is usually attributed to Jules Dumont d'Urville's use of it in 1832, but Domeny de Rienzi had used the term a year previously.
