Pacific Plate Tectonic Boundary What direction is the Pacific Plate currently moving, based on the chain of Hawaiian Islands with only the easternmost island active? The Pacific Plate contains all the plate tectonic boundary types along its boundary. What type of plate boundary is the Pacific Plate and North American Plate? Is the Pacific Plate overriding the North American Plate? Why do many oceanic volcanoes occur as long lines of volcanoes that are active at only one end? How do geologists know that the Pacific Plate is moving? The Hawaiian Islands are in the middle of the Pacific Plate, so they are just a hot spot. So, as the plate moved over the hot spot, the string of islands that make up the Hawaiian Island chain were formed. They move at a rate of one to two inches (three to five centimeters) per year. See full answer below. The northern side is a convergent boundary subducting under the North American Plate forming the Aleutian Trench and the corresponding Aleutian Islands. In the Pacific, the route of the Hawaii-Emperor volcanic chain has long been used as an indisputable witness to the movement of tectonic plates.

The Hawaiian-Emperor seamount chain is a mostly undersea mountain range in the Pacific Ocean that reaches above sea level in Hawaii.It is composed of the Hawaiian ridge, consisting of the islands of the Hawaiian chain northwest to Kure Atoll, and the Emperor Seamounts: together they form a vast underwater mountain region of islands and intervening seamounts, atolls, shallows, banks and reefs . [citation needed], In the south-west, the Pacific Plate has a complex but generally convergent boundary with the Indo-Australian Plate, subducting under it north of New Zealand forming the Tonga Trench and the Kermadec Trench.

The southern edge is a divergent plate boundary with the Antarctic Plate. This lesson will cover what tectonic plates are, how many tectonic plates there are, where they are located, how they move, what their sizes are, and how they are named. The local tectonic plate (in the case of the Hawaii hotspot, the Pacific Plate) slowly slides over the hotspot, carrying its volcanoes with it without affecting the plume. E. the lithosphere carrying hawaii slowly moves over a hotspot feeding basalt magma to the overlying volcano, Applications and Investigations In Earth Science, Dennis G. Tasa, Edward J. Tarbuck, Frederick K. Lutgens. transform plate boundary What tectonic plate is Washington state on? Currently, the Pacific plate is moving in the northwest The relative motion between these two tectonic plates is 50 mm/yr (about 2 inches/yr), but that rate is distributed across all the faults that are part of the SAFZ. plate has its specific direction of movement.
