The Pacific plate is an oceanic tectonic plate that lies beneath the Pacific Ocean. At 103 million km 2 (40 million sq mi), it is the largest tectonic plate. [2] The plate first came into existence as a microplate 190 million years ago, at the triple junction between the Farallon, Phoenix, and Izanagi plates. The Pacific plate subsequently grew ...
This plate probably broke off the Farallon plate and, when subduction in the North Pacific shifted from Siberia to the Aleutian Trench c. 50 Ma, spreading ceased between the Kula plate and the Pacific plate. [8] The Pacific plate kept growing and lineations south of the Pacific Triangle indicate the Pacific–Phoenix ridge remained a simple N ...
Relative velocity vectors of Pacific, Farallon, and Kula plates 55 million years ago (Black represents present-day land area). The Pacific-Farallon Ridge was a spreading ridge during the Late Cretaceous that extended 10,000 km in length and separated the Pacific Plate to the west and the Farallon Plate to the east.

The Pacific Plate began forming when the triple junction at the center of Panthalassa destabilized about 190 million years ago. Panthalassa , also known as the Panthalassic Ocean or Panthalassan Ocean (from Greek πᾶν "all" and θάλασσα "sea"), [ 1 ] was the vast superocean that encompassed planet Earth and surrounded the ...
Together the red, purple and black lines show the tectonic plate boundaries. I can add legends for these in the article image captions (similar to the lead image Here). As far as New Zealand, I don't quite get the gist of your point. New Zealand is at the boundary of the Australian plate and the Pacific plate, see here. This animation doesn't ...
Obduction zones occurs when the continental plate is pushed under the oceanic plate, but this is unusual as the relative densities of the tectonic plates favours subduction of the oceanic plate. This causes the oceanic plate to buckle and usually results in a new mid-ocean ridge forming and turning the obduction into subduction. [citation needed]
Relief map with the East Pacific Rise (shown in light blue), extending south from the Gulf of California. The East Pacific Rise (EPR) is a mid-ocean rise (usually termed an oceanic rise and not a mid-ocean ridge due to its higher rate of spreading that results in less elevation increase and more regular terrain), at a divergent tectonic plate boundary, located along the floor of the Pacific Ocean.
