what- The oceanic crust is composed primarily of?
basalt
Both the oceanic and continental crusts are partially composed of what material?
Both oceanic and continental crusts consist primarily of igneous rock although they both contain some sedimentary rock. Oceanic crust is composed mainly of basaltic rock, while continental crust is composed of granitic rock.
How are Ocean floor rocks are different from continental rocks?
Oceanic crust is composed primarily of the dense volcanic rock basalt. Continental crust is composed primarily of the intrusive igneous rock granite, less dense than basalt.
Most of the continental crust and oceanic crust is composed of what?
Igneous rock.
What are two differences between the continental crust and oceanic crust?
Two differences are that the oceanic crust is more dense than continental, and continental crust is composed mostly of granite, while oceanic is mostly basalt
what- The oceanic crust is composed primarily of?
basalt
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.
The crust of the sea floor is essentially composed of?
Oceanic crust is primarily composed of the rock basalt.
How is continental lithosphere different oceanic lithosphere?
Continental lithosphere is thicker and less dense than oceanic lithosphere. Continental crust is primarily composed of granitic rock while oceanic crust is composed primarily of basaltic rock.
Both the oceanic and continental crusts are partially composed of what material?
Both oceanic and continental crusts consist primarily of igneous rock although they both contain some sedimentary rock. Oceanic crust is composed mainly of basaltic rock, while continental crust is composed of granitic rock.
How are Ocean floor rocks are different from continental rocks?
Oceanic crust is composed primarily of the dense volcanic rock basalt. Continental crust is composed primarily of the intrusive igneous rock granite, less dense than basalt.
Earth's crust is a thin layer made of?
Earth's crust is made of sedimentary, metamorphic, and igneous rock. The continental crust is composed primarily of granitic rock and can be up to 45 miles thick. The oceanic crust is composed primarily of basaltic rock and can be up to 6 miles thick.
How do Oceanic crust and Continental crust vary?
Oceanic crust is thin and composed mostly of dense basaltic rock.Continental crust is thick and composed mostly of light granitic rock.
What is oceanic crust composed of?
The oceanic crust composed of sima, mafic rocks and basalt. This is the top layer of the lithosphere which is found in the ocean floor.
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.
Most of the continental crust and oceanic crust is composed of what?
Igneous rock.
What type of rock primarily makes up oceanic crust and continental crust?
Continental: granite oceanic: basalt
