Oceania has about 30 million inhabitants that cover land of about 9 million km2. Australia alone accounts for 85% of this area and concentrates 60% of the population. The other islands, which number close to 10 thousand, are divided into three large groups:
Melanesia: covers the islands located in the Northeast of Australia, from New Guinea to the Fiji Islands.
Polynesia: extends from New Zealand to Hawaii.
Micronesia: comprises the islands located in the north of Melanesia.
The ocean floor preserve evidence of past magnetic reversals because c) the ocean floor is uniformly old, preserving the earth's 4.6 billion history.

Paleomagnetism is the study of naturally occurring residual magnetism in rocks with the goal of understanding the strength and direction of the Earth's magnetic field in the geologic past and understanding the motion history of plates. Paleomagnetic fields have played a large role in confirming undersea propagation, through the discovery and understanding of seafloor anomalies. In the 1960s, geophysicists studied the magnetic properties of the ocean floor and began to discover some amazing properties.
The seabed has a system of linear magnetic anomalies in which a "band" has all its magnetic minerals oriented in the same way as the current magnetic field and the magnetic minerals in the bands alternating is oriented in the opposite direction. These bands are oriented parallel to the mid-ocean ridge system; where the ridges compensate for the transform error, the anomalies are also compensated. Symmetrical anomalies are found on either side of the ridge, and similar symmetry is found in ridges around the world.
