The Alpine Fault marks a transform boundary between the two plates, and further south the Indo-Australian plate subducts under the Pacific plate forming the Puysegur Trench. The southern part of Zealandia, which is to the east of this boundary, is the plate's largest block of continental crust.
The San Andreas Fault in California is an active transform boundary. The Pacific plate (carrying the city of Los Angeles) is moving northwards with respect to the North American plate. The Queen Charlotte Fault on the Pacific Northwest coast of North America
Map showing Earth's principal tectonic plates and their boundaries in detail. These plates comprise the bulk of the continents and the Pacific Ocean.For purposes of this list, a major plate is any plate with an area greater than 20 million km 2 (7.7 million sq mi)
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 ...
Not far off the coast of the North Pacific lies a spreading ridge; a divergent plate boundary made up of a series of breaks in the oceanic crust where melted mantle rises and solidifies, creating new ocean crust. On one side of the spreading ridge new Pacific Plate crust is made, then moves away from the
Some fracture zones such as Chile and Valdivia make up large sections of the Nazca-Antarctic plate boundary. Map of the Chile Rise and its fracture zones in Nazca and the Antarctic plates Active Pacific Ocean fracture zones are perpendicular to the mid-ocean ridges (black lines) in orange shaded region. Since the map was prepared ages not shown ...
The Australian plate (previous to 3 million years ago the Indo-Australian plate) and Pacific plate boundary is the most complex boundary of the Macquarie triple junction region, due to the unique collision of the two plates creating two convergent boundaries separated by a transform boundary.
(Definitions of "continents" are a physical and cultural construct dating back centuries, long before the advent or even knowledge of plate tectonics; thus, defining a "continent" falls into the realm of physical and cultural geography (i.e. geopolitics), while continental plate definitions fall under plate tectonics in the realm of geology.)
