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.
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 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.
The continental crust is composed of?
wht is the continental crust made of?
What type of rock is found in continental crust?
All three rock types are found in continental crust, with a preponderance of granitic type igneous rock.
What type of rock primarily makes up oceanic crust and continental crust?
Continental: granite oceanic: 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.
What is the most abundant instrusive rock in the continental crust?
The most abundant intrusive rock in the continental crust is granite. It is a coarse-grained igneous rock composed primarily of feldspar, quartz, and mica. Granite is formed from the slow cooling and solidification of magma beneath the Earth's surface.
Is the continental crust a solid liquid or gas?
The oceanic crust itself is made of solid 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.
What makes up the continents and the ocean floor?
The continental and oceanic plates are primarily igneous rock. The continental crust is granitic and the oceanic crust is basaltic.
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.
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.
What is the dominant rock type in the ocean crust and in the continental crust?
Basalt is the dominant rock in the ocean crust. And I assume Granite is dominant for 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 is the main type of rock in oceanic crust?
The crust is divided into two types: oceanic crust and continental crust. Oceanic crust, found under the ocean floor, is made of dense rocks such as basalt. It is about 7 kilometers (4 miles) thick. Continental crust, found under land masses, is made of less dense rocks such as granite.
What is the definition of continental crust?
The definition of continental crust would be the top crust that Is the first layer of crust made of rock and is the thinest layer +++ Is this in the correct category? The continental crust is that forming the bulk of the continents, primarily granite, and thicker than the basalt ocean-floor crust. Both float on the thinner aesthenosphere, the top layer of the Mantle which forms the planet's bulk.
