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.
Do All plates contain oceanic crust?
No, not all plates contain oceanic crust. The Earth's lithosphere is divided into a combination of oceanic and continental plates, each with their unique composition and characteristics. Continental plates are thicker and less dense than oceanic plates, and they mainly consist of granite and sedimentary rocks.
Does continental crust have a greater density than oceanic crust?
Yes, that is the reason oceanic crust is at a lower elevation compared to continental crust. Oceanic crust sub-ducts under the less dense continental crust. Continental crust is much older than oceanic crust, because oceanic crust is constantly being destroyed and created.
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 does the continental margin consist of?
The continental margin is the zone of ocean floor that separates oceanic crust and continental crust. It accounts for 28% of all oceanic area.
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.

Why is continental crust thicker than oceanis crust?
the weight of all the water on top of the oceanic crust compacts it making it thinner but denser.

What is a characteristic of subduction?
The correct answers are - B. Where oceanic crust meets continental crust, and C. Earthquakes.Subduction zones appear only on places where a crust of lower density (oceanic crust) meets a crust of higher density (continental crust).On the places where the oceanic crust meets the continental crust, the oceanic crust goes beneath the continental crust, this makes changes and readjustments in the inner part of the crust, and plus there's significant pressure from the mantle layer from beneath, so earthquakes are a very common occurrence.Check all that apply. A. Broad river deltas B. Where oceanic crust meets continental crust C. Earthquakes D. Two continents collide
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.
Is the oceanic crust older then the continental crust?
Well, the earth was built all by itself or more preferably god made it but, the oceanic crust and the continental crust are both aged the same. Whenever this earth was created like 40,000 or billion years ago. It's really quite simple to figure it out by yourself.
What are the two kinds of crust?
Earths crust is the outer shell of our planet. The Earth has two types of crust. Continental crust contains igneous, sedimentary and metamorphic rocks that covers the continents. Oceanic crust contains igneous basalt rocks derived from the upper mantle that cover the all the ocean floors. The igneous rocks are covered with sediments carried into the oceans from large rivers like the Amazon and Mississippi Rivers.
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.
