yes but oceanic crust is younger than continental crust because of deep sea trenches
What else can I help you with?
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.
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.
What plate contains only oceanic crust?
The Pacific Plate is predominantly oceanic crust. It is one of the Earth's largest tectonic plates and is mostly submerged beneath the Pacific Ocean.
Volcanoes only occur in oceanic crust?
Volcanoes do not only occur in oceanic crust; they can also be found in continental crust. While many volcanic eruptions happen at mid-ocean ridges or subduction zones associated with oceanic plates, continental volcanoes can form due to rifting, hotspots, or tectonic activity in continental regions. For example, the Cascade Range in the Pacific Northwest of the U.S. features volcanoes formed on continental crust. Thus, both oceanic and continental crust can host volcanic activity.
What are the four lithosphere plate that consist of only oceanic crust?
The four lithospheric plates that consist primarily of oceanic crust are the Pacific Plate, the Nazca Plate, the Cocos Plate, and the Juan de Fuca Plate. These plates are mainly located beneath the world's oceans and are characterized by thinner, denser crust compared to continental plates. Their movements are responsible for various geological phenomena, including earthquakes and volcanic activity in adjacent areas.
How many tectonic plates are made of only oceanic crust?
There are seven tectonic plates that are primarily made up of oceanic crust: the Pacific Plate, Nazca Plate, Cocos Plate, Juan de Fuca Plate, Philippine Sea Plate, Arabian Plate, and the Scotia Plate. These plates are generally located in the ocean basins and are involved in the movement and interactions of Earth's tectonic plates.
Which plates includes only oceanic crust with no continents?
The plates that include only oceanic crust with no continents are the Pacific Plate, Nazca Plate and the Juan de Fuca Plate. These plates are mainly composed of basaltic oceanic crust and are located in the ocean basin areas.
Do lithospheric plates include both continental crust and oceanic crust?
Yes, lithospheric plates can include both continental and oceanic crust. These plates are composed of the rigid outer layer of Earth's surface, which consists of the upper part of the mantle and the crust. Continental crust is less dense and thicker than oceanic crust, but both can form part of lithospheric plates.

What plate contains only oceanic crust?
The Pacific Plate is predominantly oceanic crust. It is one of the Earth's largest tectonic plates and is mostly submerged beneath the Pacific Ocean.
What two types of crust are the tectonic plates made from?
Short Answer: The Earth has two types of crust, continental crust and oceanic crust. Basaltic rocks are the main component of oceanic crust. Continental crust consists mainly of lower density granitic rocks. The Better Answer: Tectonic plates and the Earth's crust are not the same thing. Tectonic plates are made of the Earth's crust, plus the upper layers of the Earth's mantle. Together the crust and the more solid upper mantle form the lithosphere. The crust itself is relatively thin, varying from a few kilometers thick to nearly a hundred kilometers. With the material of the mantle, the tectonic plates are 50 to 200 kilometers thick. Some plates are entirely continental and some are entirely oceanic and some are combined. Continental crust and oceanic crust are different in make up and properties. The continental crust has a density of about 2.7 g/cm3 and is mostly granitic, made of silicate materials with more aluminum and less iron and magnesium. Continental crust is generally thicker, in the range of 25 to 70 kilometers. Oceanic crust is more dense (density of about 2.9 g/cm3) and the average oceanic thickness is in the range of 7-10 kilometers. Oceanic crust is primarily basalt, composed of silicate material which is rich in iron and magnesium. Though only 40% of the Earth's surface is continental crust, there is more of it because it is thicker. Continental crust is about 70% of the volume of Earth's crust. Both types of crusts are less dense than the material of the Earth's mantle (density of about 3.3 g/cm3), so the "float" on the mantle.
Are subducting plate and oceanic plate the same?
No, subducting plate and oceanic plate are not the same. An oceanic plate is a type of tectonic plate that lies beneath the ocean, while a subducting plate refers to an oceanic plate that is descending beneath another tectonic plate at a convergent boundary. Subducting plates are a specific category of oceanic plates.
Volcanoes only occur in oceanic crust?
Volcanoes do not only occur in oceanic crust; they can also be found in continental crust. While many volcanic eruptions happen at mid-ocean ridges or subduction zones associated with oceanic plates, continental volcanoes can form due to rifting, hotspots, or tectonic activity in continental regions. For example, the Cascade Range in the Pacific Northwest of the U.S. features volcanoes formed on continental crust. Thus, both oceanic and continental crust can host volcanic activity.

Is oceanic crust is usually thicker than continental crust?
No. Oceanic crust is heavier and denser than continental crust, but is actually thinner. Continental crust is believed to actually extend down into the magma of the mantle (upon which crust floats) more deeply than oceanic crust, similar to how a huge ice cube will not only be larger above the surface of water than a smaller ice cube, but will extend more deeply into a glass than a small ice cube ... so not only does continental crust extend higher on the surface (since it is continental crust, it has dry land above the ocean floor), but the 'bottom' of the crust also extends deeper into the earth. Oceanic crust is thus thinner than continental crust, but made of denser, heavier rock (which is why it subducts under continental crusts where continental and oceanic plates converge).
What are the 3 plates earth is made of?
The earth is not made up of only 3 plates. Some plates are the north and south American plates, the nazca plate, the pacific plate, the Australian plate, the eurasian plate, and the African plate. The plates are made from an igneous rock called basalt, and it also has some granite.
