It is about 20 miles or 30 kilometers.

∙ 12y agoContinental crust is actually much thicker than oceanic crust. This is because Continental crust has been formed over a much longer period of time, and especially so due to sea-floor spreading (as new crust is constantly produced). Since uplift constantly occurs in Continental crust but not in Oceanic, the Continental crust is naturally thicker.
(Furthermore, you could consider the way in which the oceanic crust is lower than sea-level as proof that it is thinner as it is comparable to wooden blocks floating on water: the more is above the water, the more is below. Therefore by this principal you know that Continental crust extends far lower than Oceanic crust, and hence is thicker)

Is the continental crust thinner and denser in most areas than the oceanic crust?
No, in fact it is the opposite. The continental crust is thicker and less dense than the oceanic crust.
Why is the oceanic crust is more active than the continental crust?
This is because the Oceanic Crust is denser and thinner than the Continental Crust and is actively being created by the forces of the magma at different mid-oceanic ridges.
Why the crust is thinner than the ocean floor?
The crust is the Ocean floor. There is Oceanic Crust, And then There is Continental Crust.
Why is it important to understand how oceanic and continental crusts move?
The top layer of the Earth's surface is called the crust (it lies on top of the plates). Oceanic crust (the thin crust under the oceans) is thinner and denser than continental crust. Crust is constantly being created and destroyed; oceanic crust is more active 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.
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.
Why is the ocean crust thinner than the continental crust?
It is not. The oceanic crust is thinner than the continental crust!
Why is oceanic crust lower than the continental crust?
Oceanic crust is thinner and of greater density than continental crust.
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 :)
Is earth's continental crust thicker or thinner than the oceanic crust?
On average, it is much thicker than oceanic crust.
Is the continental crust thinner and denser in most areas than the oceanic crust?
No, in fact it is the opposite. The continental crust is thicker and less dense than the oceanic crust.
Why is the oceanic crust is more active than the continental crust?
This is because the Oceanic Crust is denser and thinner than the Continental Crust and is actively being created by the forces of the magma at different mid-oceanic ridges.
What is the thinnest layer of the earth's crust.?
Oceanic crust is generally thinner than continental crust.
Why the crust is thinner than the ocean floor?
The crust is the Ocean floor. There is Oceanic Crust, And then There is Continental Crust.
Is the earth's crust thicker under the ocean?
Oceanic crust is thinner and denser than continental crust.
Is the continental crust more dense than the oceanic crust?
Oceanic crust is thinner (about 6-8 km in total) and more dense. Continental crust is about 30-50 km thick.
