What else can I help you with?
When the ocean floor collides with a crustal plate what happens?
it subducts underneath the crustal plate
Continental and oceanic crust?
The two parts of the crust that make up the earth. The continental supports land while the oceanic crust is at the bottom of the ocean. - Anonymous
Does theory continental drift state that new ocean crust is formed at ocean ridges and destroyed at deep sea trenches?
No, the theory is that Seafloor spreading state that the new ocean crust is formed at ocean ridges and is destroyed at deep sea trenches.
Why can continental crust displace more of the mantle than oceanic crust can?
the mantle is a hot ocean of lava basically and on it floats a series of tectonic plates, on the surface of the plates is the crust. there is your answer hope it helps.
What are the levels of the ocean called?
The continental shelf, continental slop and the ocean floor
What is a continental crust?
the continental crust is the plate crust formed under the continent (less density) as opposed to oceanic crustformed under the ocean(higher density)
What is a Earth crust?
the continental crust is the plate crust formed under the continent (less density) as opposed to oceanic crustformed under the ocean(higher density)
Does earth's crust have the same density?
No, the density of Earth's crust varies depending on the type of rock and location. Generally, continental crust is less dense than oceanic crust. Continental crust is composed mostly of granite and has an average density of about 2.7 g/cm^3, while oceanic crust, which is mainly basalt, has an average density of about 3.0 g/cm^3.
What is the compition for the crust?
Crust is made up of mainly granite, a felsic rock wit a lower density than basalt, what makes up the ocean's crust, thus why the continental crust rises up compared to ocean crust.
Ocean crust dives below continental crust because of what?
Because of its higher density, and gravity. One part of plate tectonic theory.
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.
Why is the ocean crust thinner than the continental crust?
It is not. The oceanic crust is thinner than the continental crust!
Ocean crust dives below continental crust because?
Ocean crust is denser
How does the age of oceanic crust compare to the age of continental crust?
Oceanic crust is generally younger than continental crust. Oceanic crust is continuously formed at mid-ocean ridges through volcanic activity and then gradually moves away from the ridge, undergoing processes that make it relatively young compared to the older continental crust.
How does the age of the oldest continental crust compare to the of the oldest ocean crust?
The oldest continental crust would be between three and one half to four billion years older than the oldest oceanic crust. This is due to the fact that ocean plates are subducted under the continental plates, subjected to partial melt and essentially recycled in the mantle before reforming.

How does the thickness of oceanic crust compare to the thickness of continental crust?
Oceanic crust is generally thinner, with an average thickness of about 7-10 km, while continental crust is thicker and can range from 20-70 km or more. This difference in thickness is due to variations in composition and density of the crust types.
