What is the source material in basaltic magma?
Oceanic crust and oceanic sediments.
What happens to mantle rock descending oceanic crust scrapes past continental crust?
The mantle rock descending from the oceanic crust causes the water in oceanic crust to be released. This lowers the melting point of the rock and causes it to melt.
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.
What characteristics of continental crust allow it to float higher on the mantle than oceanic cruast?
Continental crust is less dense than oceanic crust.
What part of the earth is the crust and the very top of the mantle?
The part of the earth's crust that is at the very top of the mantle is the oceanic crust. Or combined with the upper mantle it is also known as the lithosphere.
True or false magnetic stripes on the ocean floor are places where oceanic crust sinks back to the mantle?
F
Is magnetic stripes on the ocean floor the places where oceanic crust sinks back to the mantle?
it is right in your book soo... you should be able to answer this
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 is 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 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 kind of crust usually goes into the mantle?
Oceanic crust gets subducted into the mantle.
What is the source material in basaltic magma?
Oceanic crust and oceanic sediments.
Does the continental or the oceanic crust extend farther into the mantle?
The continental crust because it is thicker than the oceanic crust
What happens to mantle rock descending oceanic crust scrapes past continental crust?
The mantle rock descending from the oceanic crust causes the water in oceanic crust to be released. This lowers the melting point of the rock and causes it to melt.
Why does the oceanic crust sit lower in the mantle than the continental crust?
Oceanic crust is more dense than continental crust.
What happens to old oceanic crust as molten materials rises from the mantle?
The older oceanic crust moves away from the spreading center and is eventualy subducted back into the mantle.
What happens to old oceanic crust as new molten material from the mantle?
The older oceanic crust moves away from the spreading center and is eventualy subducted back into the mantle.
