According to the plate tectonic theory a plate can be made up of?
A tectonic plate consists of a piece or fragment of the earth's lithosphere, which is in turn composed of the earth's crust and that portion of the earth's upper mantle which behaves as a brittle solid through which fractures can propagate.
What is a section of the lithosphere that slowly moves over the asthenosphere carrying pieces of continental and oceanic crust?
The section of the lithosphere that slowly moves over the asthenosphere carrying pieces of continental and oceanic crust is known as a tectonic plate. These plates are part of the Earth's outer shell and are divided into several major and minor plates that interact with each other at plate boundaries. The movement of these plates is driven by the heat generated from the Earth's core, causing them to either converge, diverge, or slide past each other, leading to various geological phenomena such as earthquakes, volcanic eruptions, and mountain formation.
Is all oceanic crust below sea level?
No. The Hawaiian Island Chain, for instance, sits on top of oceanic crust.
How do the densities of oceanic crust and continental crust influence what happens when an oceanic plate coverages with a continental plate?
Oceanic crust is more dense than continental crust. All that water weight compresses the heck out of the material in the plate and also the oceanic crust contains larger percentages of denser elements such as magnesium and iron than the continental crust which also contributes to it's higher density. This sets the conditions for what happens. The more dense oceanic crust will "dive under" continental crust because it is more dense, and all because of the difference in densities.
What part of earth contains plates?
The lithosphere is the part of the Earth that contains tectonic plates. These plates are divided pieces of the lithosphere that float on the semi-fluid asthenosphere beneath them.
Name a plate that is entirely made of continental crust?
All major plates contain both continental and oceanic crust except for the Pacific and Nazca plates.
How many tectonic plates are composed of only continental crust?
Some geologists believe there are no tectonic plates composed solely of continental crust, as plates typically consist of both continental and oceanic crust. The concept of a plate composed entirely of continental crust is not widely accepted in the field of plate tectonics.
How big is the indo-australian plate?
No, it is not an oceanic plate. It is a continental plate but with oceanic crust. Crust is different from plate. A plate is made up of many crust. The crust under the ocean is oceanic crust, while the crust where continent is found is called continental crust. Most of the plates are made up off both continental and oceanic crust. If a plate has continental crusts, then it is a continental plate. Only if a plate is all made up of oceanic crusts, meaning that there is no land on it, then the plate is called oceanic plate. In the world, the major oceanic plates include Pacific Plate, Nazca Plate, Cocos Plate and Philippines Plate. Other are all continental plate.
What is the difference between Continental plates and Tectonic plates?
Continental plates are tectonic plates. They are tectonic plates upon which continents rest, and they move as do all tectonic plates. Basically, there is no difference, other than the fact that oceanic plates are another type of tectonic plate.
What is the large plate and how is it different from all the other plates?
The Pacific plate is the largest of all,consisting of 20 percent of the Earth's crust. All of these plates, with the exception of the Pacific plate, contain both continental and ocean crust. Smaller plates include the Caribbean and Arabian plates.
How does subduction explain why ocean crust is all 200 million years old or less?
Subduction occurs when two tectonic plates collide; it is the act of one of the two plates being driven below the other. Oceanic crust is more dense than continental crust, so it will be driven under the continental crust virtually every time. When the crust is subducted, it gets driven further and further into the mantle, where it melts and becomes magma once more, ending its timeline as crust. It takes approximately 200 million years from its creation in an oceanic ridge over a divergent margin (the area where two tectonic plates are moving apart) for the crust to reach the end of its timeline.
Do continental plates move faster than oceanic plates?
No, oceanic plates move faster than continental plates. This is due to the density of the oceanic plates (basalt is denser). For example, the fastest moving plates are the Pacific plate, Cocos plate, and Nazca plate. All oceanic.
How is the oceanic crust recycled?
Convection in the mantle helps to recycle the oceaniccrust, not all of Earth's crust. There are two different parts to the crust. Oceanic and Continental. The Oceanic gets recycled, so when Scientists measure the age of the rocks, they're young.
