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 are three differences between oceanic and continental crust?
Continental crust is mostly composed out of granite, oceanic crust out of basalt.Continental crust is thicker and less dense than oceanic crust.
What are the three differences between oceanic and Continental crust?
CONTINENTAL CRUST is 35km of thickness and oceanic is 7 km. i hope that helped
Why does continental crusts stand higher on the mantle then oceanic crust?
Because Oceanic crust is more dense and the Continental Crust is mountains which are a lot taller than sea floor.
Both oceanic and continental crust are composed of this?
Brittle rock.
Explain the significance of the fact that the lithosphere is primarily composed of basalt while the crust is composed primarily of granite?
The lithosphere is composed of the oceanic and continental crust, along with the brittle uppermost mantle. The continental crust is mainly granitic, and the oceanic crust is primarily basalt.
What are the major components of the Earth?
The lithosphere is composed of the uppermost mantle which is attached to the continental and oceanic crust.
What is composed of oceanic continental crust and upper mantle?
That would be the lithosphere which is split into tectonic plates.
Does the continental or the oceanic crust extend farther into the mantle?
The continental crust because it is thicker than the oceanic crust
Why does the oceanic crust sit lower in the mantle than the continental crust?
Oceanic crust is more dense than continental crust.
How do continental crust differ from oceanic?
Continental crust is predominantly composed mostly of rock of a granitic composition, higher in silica and aluminum, with layers of sedimentary rock above. Oceanic crust is predominantly basaltic (higher in iron and magnesium), darker, thinner, more dense, and formed from rapid cooling of lava.
What comprises the Earth's lithosphere?
pie is awsome
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.
Why does the continental crust float higher on the mantle than on the oceanic crust?
the oceanic crust is more dense therefore it sinks lower than continental crust
What characteristics of continental crust allow it to float higher on the mantle than oceanic cruast?
Continental crust is less dense than oceanic crust.
Why is oceanic crust always subducted underneath the continental crust?
Oceanic crust subducts under continental crust because it is denser. Continental crust's density is too low for it to be forced into the mantle.
