How are oceanic crust and continental crust different?
Oceanic crust is thinner and more dense, while continental crust is thicker and less dense.
What is the difference of continental crust and oceanic crust?
Two differences are that the oceanic crust is more dense than continental, and continental crust is composed mostly of granite, while oceanic is mostly basalt
Why does the oceanic crust sit lower in the mantle than the continental crust?
Oceanic crust is more dense than continental crust.
Which type of crust is thicker oceanic crust or continental crust?
I think it is the continental crust
What happens during subduction?
Dense oceanic crust slides under less dense continental crust
Why does ocean crust dive below continental crust?
The ocean crust dives below the continental crust due to a collision. This collision involves the two types of crust and since the oceanic crust is denser, it sinks to the bottom while the less dense continental crust rises to the top.
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.
What is difference of the continental crust and the oceanic crust?
Continental crust is thicker but less dense, and oceanic crust is thinner but more dense, making it heavier.
Would it be easier to drill through the oceanic crust or the continental crust?
Continental crust is easier. Continental crust is less dense than oceanic crust, which is made of basalt. (Basalt is very dense.)
Is the oceanic crust dense?
Yes. It is more dense than continental crust.
What layer of the crust is the most dense?
Oceanic crust is more dense than continental crust.
Why does the oceanic sink beneath continental crust at convergent boundaries?
The continental crust is less dense than the oceanic crust. That's the reason we find that the oceanic crust sinks (subducts) beneath the continental crust.Continental crust is less dense than oceanic crust and so cannot sink below it.
Why does the continental crust float higher on the athenosphere than oceanic crust?
The continental crust is less dense
How are oceanic crust and continental crust different?

What is the difference of continental crust and oceanic crust?

Why do convergent oceanic plates subduct but continental plates do not usually respond in this way?
Oceanic crust is denser than continental crust, dense enough to sink into the mantle. Continental crust is not dense enough to do this.
Why does the oceanic crust sit lower in the mantle than the continental crust?
Oceanic crust is more dense than continental crust.
