The oceanic crust.
The plate includes both continental and oceanic crust.
New oceanic crust is constantly being made at the mid-oceanic ridges.
The Pacific Ocean floor subducted under this oceanic crust between the continents.
The oceanic crust is made up of rocks much younger than the Earth itself.
This process results in parallel sections of oceanic crust of alternating magnetic polarity.
Most oceanic crust in the ocean basins is less than 200 million years old.
The thinnest part of the crust is known as oceanic crust and is found under oceans.
Oceanic crust is the uppermost layer of the oceanic portion of a tectonic plate.
At these fiery spots, oceanic crust dives back into Earth's hot mantle.
Additionally, continental crustal material is transferred to oceanic crust by sedimentation.
This oceanic crust has primarily been subducted under the North American plate, and the Eurasian Plate.
The relative permanence of continental crust contrasts with the short life of oceanic crust.
The Scotia Plate is made of oceanic crust and continental fragments now distributed around the Scotia Sea.
As the Atlantic Ocean widened, North America and South America were pushed westward,separated for a time by oceanic crust.
Continental crust is also less dense than oceanic crust, whose density is about 2.9 g/cm3.
Age of oceanic crust is symmetrical with respect to the spreading axis and increases with distance from it.
The Mariana Trench was created by the process that occurs in a subduction zone,where two massive slabs of oceanic crust collide.
When hotspots occur beneath oceanic crust, the resulting molten rock will often produce basaltic lavas.
The oceanic crust displays a pattern of magnetic lines, parallel to the ocean ridges, frozen in the basalt.
Granite tends to form at continental subduction zones where oceanic crust is subducting beneath continental crust. .
Why is the oceanic crust relatively fresh and what force has caused the continental crust to dive?
The subduction process consumes older oceanic lithosphere,so oceanic crust is seldom more than 200 million years old.
Oceanic crust is significantly simpler than continental crust and generally can be divided in three layers.
It includes much of the continent of Africa,as well as oceanic crust which lies between the continent and various surrounding ocean ridges.
This oceanic crust gets mixed into the rest of the mantle, which because of its high temperature and pressure slowly flows and fuels the world's volcanoes.
Paleo-geology of the Pacific PlateEdit The Pacific Plate is almost entirely oceanic crust, but it contains some continental crust in New Zealand, Baja California, and coastal California.
It also includes oceanic crust extending westward to the Mid-Atlantic Ridge and northward to the Gakkel Ridge.
This resulted in rapid formation of oceanic crust at ridges andhot spots, and rapid recycling of oceanic crust at subduction zones.
The oldest large-scale oceanic crust is in the west Pacific and north-west Atlantic- both are up to 180- 200-million-year old.
