Pacific Plate

A Dictionary of Earth Sciences | 1999 | 432 words | Copyright

Pacific Plate Although it is the largest present-day lithospheric plate, the Pacific Plate is shrinking because most of its margins, apart from the East Pacific Rise and the Pacific–Antarctic Ridge, are subduction zones (e.g. the Aleutian, Kuril, Japan, Izu-Bonin, and Marianas subduction zones). The Pacific Plate is the only major plate to consist of nothing but oceanic crust, parts of which date from the Triassic Period.
