What are places where oceanic crust sinks back to the mantle?
No. Mid oceanic ridges are the places where new oceanic crust are forming.
What happens to mantle rock descending oceanic crust scrapes past continental crust?
As the oceanic crust descends beneath the continental crust, the mantle rock is subjected to high pressure and temperature. This causes the mantle rock to partially melt, producing magma that can rise to the surface and form volcanoes. The interaction of the descending oceanic crust with the continental crust can also lead to earthquake activity.
Explain why continental crust can displace more of the mantle than oceanic crust can?
Continental crust is generally thicker and less dense than oceanic crust, allowing it to displace more of the mantle beneath it. The buoyancy of continental crust enables it to float higher on the mantle compared to the denser oceanic crust, which sinks deeper into the mantle. Additionally, the composition of continental crust, which includes lighter materials like granite, contributes to its ability to displace a larger volume of mantle. This difference in density and thickness results in continental crust having a greater gravitational pull on the mantle compared to oceanic crust.
What are the 2 divisions of the crust?
The two divisions of Earth's crust are the continental crust and the oceanic crust. The continental crust is thicker and less dense, mainly composed of granite rocks, while the oceanic crust is thinner and denser, primarily made up of basalt rocks.
What happens to the old oceanic crust as new molten material rises from the mantle?
The older oceanic crust moves away from the spreading center and is eventualy subducted back into the mantle.
Is there magnetic strips on the ocean floor are places where oceanic crust sink back to the mantle?
Is there magnetic stripe son the ocean floor are places where oceanic crust sink back to the mantle
What are places where oceanic crust sinks back the the mantle?
A "subduction zone".
Where are the places where oceanic crust sinks back into the mantle.?
A "subduction zone".
What are places where oceanic crust sinks back to the mantle?
No. Mid oceanic ridges are the places where new oceanic crust are forming.
What is the oceanic lithosphere?
The lithosphere is composed of crust and hard upper mantle. The oceanic lithosphere would be hard upper mantle and basaltic oceanic crust.
What is oceanic lithosphere?

What kind of crust usually goes into the mantle?
Oceanic crust gets subducted into the mantle.
Does the continental or the oceanic crust extend farther into the mantle?
The continental crust because it is thicker than the oceanic crust

The interaction of the descending oceanic crust with the continental crust can also lead to earthquake activity.
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.

Is the oceanic crust made of solid or liquid?
The oceanic crust is primarily made of solid rock, primarily basalt. However, beneath the oceanic crust, there is a layer of partially molten rock called the mantle that flows slowly over time.
