The continental shelf is normally made out of continental crust, the oceanic crust begins at the base of the continental rise. However in most places the oceanic crust near the continental margins is covered by continental sediments (eroded form the continents) carried down onto the Oceanic planes by deep sea canyons running off the continental rises.
What else can I help you with?
What types of crust can be found in the lithosphere?
The lithosphere can have two main types of crust: continental crust and oceanic crust. Continental crust is thicker, older, and less dense than oceanic crust. Oceanic crust is thinner, younger, and denser, primarily composed of basaltic rocks.
Crust under the ocean is called?
Crust under the oceans is called oceanic crust.
What is continental and oceanic crust?
Continental crust is the thicker, less dense, and older type of crust found beneath continents, primarily composed of granite and sedimentary rock. Oceanic crust is the thinner, more dense, and younger type of crust located beneath oceans, primarily composed of basalt. The boundary between continental and oceanic crust is known as the continental-oceanic crust boundary.
What are the two types of crust on the earth?
There are two types of crust, and they are the oceanic crust and the continental crust. Oceanic crust is thinner yet more dense than continental crust, and continental crust is on average older than oceanic crust :)
Which is thicker continental crust oceanic crust?
Continental crust is the thicker of the two: it extends far beneath and above the Oceanic crust.
What does the oceanic crust begin at?
It begins at the continental rise.
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
What is older the oceanic crust or the continental crust?
Continental crust is far older than oceanic crust.
Is the continental crust thinner than the oceanic crust?
It is not. The oceanic crust is thinner than the continental crust!
Is oceanic crust near the mid-ocean ridge older thean oceanic crust farther away from the ridge?
Its oceanic crust
What are three differences between oceanic and continental crust?
Continental crust is mostly composed out of granite, oceanic crust out of basalt.Continental crust is thicker and less dense than oceanic crust.
