Why does the oceanic crust sit lower in the mantle than the continental crust?
Oceanic crust is denser than continental crust due to its composition and age, causing it to sink lower into the mantle. The oceanic crust is also thinner and has been subjected to more intense heat and pressure, which contributes to its lower position in the mantle compared to the thicker, lighter continental crust.
Oceanic crust is than continental crust.?
younger
Why does the continental crust float higher on the mantle than on the oceanic crust?
Continental crust is less dense and thicker than oceanic crust, causing it to float higher on the mantle. The continental crust is also compositionally different, with a greater amount of less dense materials like granite compared to the basaltic composition of oceanic crust. This difference in density and composition results in the continental crust floating higher on the mantle.
Is earth's continental crust thicker or thinner than the oceanic crust?
On average, it is much thicker than oceanic crust.
Which is thicker continental crust oceanic crust?
Continental crust is the thicker of the two: it extends far beneath and above the Oceanic crust.

The oceanic crust is also thinner and has been subjected to more intense heat and pressure, which contributes to its lower position in the mantle compared to the thicker, lighter 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!
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.
What is older the oceanic crust or the continental crust?
Continental crust is far older than oceanic crust.
Oceanic crust is than continental crust.?
younger
What characteristics of continental crust allow it to float higher on the mantle than oceanic cruast?
Continental crust is less dense than oceanic crust because it is thicker and composed of lighter materials, such as granite. This lower density allows continental crust to "float" higher on the more dense mantle beneath it, creating continents.
What crust is older in years the continental or the oceanic?
Continental crust is far older than oceanic crust.
What portion of the earths crust is more dense oceanic or contenintal?
Oceanic crust is denser than continental crust. Oceanic crust has a density of about 3 g/cm^3, while continental crust has a lower density of about 2.7 g/cm^3.

Does the continental or the oceanic crust extend farther into the mantle?
The continental crust because it is thicker than the oceanic crust
Is the oceanic crust dense?
Yes. It is more dense than continental crust.
