   1. Oceania

   Oceania is the smallest of the continents. Its area is 9.008.458 kilometers, from which 7.741.220 km2 are from Australia. The rest is constituted by over 10.000 islands, gathered into Melanesia, Micronesia, Polynesia, Australia and New Zealand.

   Most of these small islands are formed by corals, animals which lived in colonies, whose members are joined between them by a calcareous red or rose polypier. In this way, great barriers which surface from the sea are formed. They used to form circles with a lake in the middle. These formations are called atolls.

   Oceania is a continent sparsely populated, because it has 32.000.000 inhabitants. In Australia and New Zealand most of the people is white, descending from English. In Melanesia most are black, and in Polynesia the most common ethnic group is olive-skinned.
