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 else can I help you with?
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.
Oceanic crust is than continental crust.?
younger
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.
The crust of the sea floor is essentially composed of?
Oceanic crust is primarily composed of the rock basalt.
What is the name of ocean crust?
The name of the crust beneath the oceans is called "oceanic crust." It is thinner and younger than continental crust and primarily composed of basaltic rocks.
What are the 2 types of crust that cover the earth's surface?
The two types of crust that cover the Earth's surface are oceanic crust, which is thinner and denser, and continental crust, which is thicker and less dense. Oceanic crust is mainly composed of basalt, while continental crust is primarily composed of granite.
What are the two types of crust on the earth?
There are two types of crust, and they are the oceanic crust and the continental crust. Oceanic crust is thinner yet more dense than continental crust, and continental crust is on average older than oceanic crust :)
Most of the continental crust and oceanic crust is composed of what?
The continental crust is primarily composed of granite and sedimentary rocks, while the oceanic crust is mainly composed of basalt. Both types of crust consist mainly of silicate minerals such as feldspar, quartz, and mica.
Why is oceanic denser than continental crust?
The oceanic crust is composed mainly of basalt, rich in iron and magnesium. The continental crust is composed mainly of granite, rich in aluminum. Although they are both rich in oxygen and silicon, the rocks that compose the oceanic crust are of higher density than the rocks that compose the continental crust.
Both oceanic and continental crust are composed of this?
Both oceanic and continental crust are composed primarily of igneous rocks, but they have different overall compositions. Oceanic crust is primarily made up of basalt, which is a type of volcanic rock, while continental crust is predominantly composed of granite, a type of intrusive igneous rock. Additionally, continental crust is generally thicker and less dense than oceanic crust.
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 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.
