What is the difference between contiental crust and oceanic crust?
Continental crust is on top of the oceanic crust Continental crust is made of granite whereas oceanic crust is made of basalt Continental crust is partly above sea level and partly below whereas oceanic crust is always below sea level.
What crust is older in years the continental or the oceanic?
Continental crust is far older than oceanic crust.
What are four differences between the oceanic crust and the continental crust?
1. The Oceanic crust is dense while the Continental crust is relatively lighter. 2. The Oceanic crust consists of Silicon and Magnessium, while the Continental crust has Silicon and Alluminium. 3. The Oceanic crust is thin, while the Continental crust is thick. 4. The Oceanic crust makes up the ocean floor, while the Continental crust carries the continents.
Which rock makes continental and oceanic crust?
Continental crust is made of granite. Oceanic crust is made of basalt.
What are the three differences between oceanic and Continental crust?
CONTINENTAL CRUST is 35km of thickness and oceanic is 7 km. i hope that helped
Why is oceanic crust always subducted underneath the continental crust?
Oceanic crust subducts under continental crust because it is denser. Continental crust's density is too low for it to be forced into the mantle.
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?
Continental crust is less dense than oceanic crust.
Why oceanic crust is always subducted underneath continental crust?
Due to the higher density of the oceanic crust it is subducted underneath the continental crust.
What is the place where the oceanic crust is forced under the continental crust?
This is called a subduction zone.
What happens when a plate carrying oceanic oceanic crust collides with a plate carrying continental crust?
The contiental cdrust is forced under the continental crust in a process called subduction.

Why do oceanic plates subduct?
Bacause they are composed of material that is denser than that of the continental crust. As such ocernic crust is less bouyant than contiental crust and so where oceanic crust collides with continental crust, the oceanic srust tends to be forced beneath the continetal crust.
What are two differences between the oceanic crust and the continental crust?
The oceanic crust consists of heavier rock, mostly Basalt, so that if a oceanic plate collides with a continental plate the oceanic plate will be forced down below the continental plate, forming island arcs.continental plates are thicker than oceanic plates.

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.
The process of an oceanic plate colliding with and descending underneath a continental plate?
The oceanic crust is subducted underneath the continental crust. This process is known as subduction.
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.
