The earths crust layer is constantly moving because of the layer beneath it that has all the liquid magma. The magma needs a place to escape because of the pressure it takes on so where does it go, it goes up and pushes on the earths crust to escape. The places it escapes are pretty much where they follow the path of least resistance and that is where the plates of the earth crust meet. The Atlantic ridge which is the second biggest in the world has eruptions all the time constantly added to land to the sea and pushing other plates together. So in short the plates move because the layer beneath it are always on the move as well.
What else can I help you with?
Why does the oceanic crust move below continental crust?
The basaltic oceanic crust is more dense than the granitic continental crust. Therefore, when the two meet at plate margins, the oceanic crust usually subducts beneath the continental plate.
When a continental crustal plate collides with an oceanic crustal plate the continental crust is forced to move over the oceanic crust What is the primary reason that the continental crust stays on?
The continental crust is less dense and thicker than oceanic crust, which allows it to stay on top during a collision. The low density and greater thickness of continental crust help it resist subduction beneath the oceanic crust.
How are continental crust and oceanic crust are alike?
Oceanic and continental crust contain the same elements. Both also move and shift and grow continuously. They are different because of their density.
How are oceanic crust and continental crust alike How are they different?
Oceanic and Continental crusts are alike because they both shift and move and grow. They differ by there rock types. Oceanic crust is made up of dense basalt while continental crust is made up of less dense granite.
Do tectonic plates consist of continental or oceanic crust?
Tectonic plates consist of both continental and oceanic crust. The Earth's lithosphere is divided into several large and small plates that constantly move and interact with each other. Some plates are predominantly made up of continental crust, while others are mostly composed of oceanic crust.
Oceanic crust is lighter than the continental crust?
No, the oceanic crust is denser. That's why the land areas "float" so much higher than the ocean bedrock.
What is oceanic-oceanic subduction?
Oceanic crust sinking under a plate with continental crust
Is the oceanic crust felsic or mafic?
Oceanic crust is mafic.
What does it mean if the oceanic crust 0?
the oceanic crust is 0.
What crust is more dense oceanic or continental crust?
Oceanic crust is significantly denser.
Where are the youngest portion of Earth's crust found?
The youngest parts of the Earth's crust are found in the oceanic crust. This crust is continuously being created at the mid-oceanic ridges.
Would it be better to drill through the earths crust or the oceanic crust?
oceanic crust
