Where does the oceanic crust begin?
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.
Oceanic crust is what than continental crust?
Oceanic crust is thinner and denser than continental crust.
What layer of crust averages 25 miles in thickness?
Continental crust.
Differences of the continental crust and oceanic crust?
Thickness - continental = much thickerDensity - oceanic crust is denser than continental, which is why the oceanic crust subducts under the continental at destructive plates boundaries.
Which is denser Oceanic Crust or Continental Crust?
The Oceanic crust is denser than the continental 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.
Is the continental crust thinner than the oceanic crust?
It is not. The oceanic crust is thinner than the continental crust!
Oceanic crust is what than continental crust?
Oceanic crust is thinner and denser than continental crust.
What is older the oceanic crust or the continental crust?
Continental crust is far older than oceanic crust.

Which is thicker continental crust or oceanic crust?
Continental crust A+
Which is thicker continental crust oceanic crust?
Continental crust is the thicker of the two: it extends far beneath and above the Oceanic crust.
Which is an example of a terrane?
oceanic crust and continental crust collide, with the continental crust subducting under the oceanic
What crust is older in years the continental or the oceanic?
Continental crust is far older than oceanic crust.
