What is the general composition of earths continental crust?
Water
Why is the main reason that oceanic crust is heavier than continental crust?
Oceanic crust is mafic in composition and continental crust is felsic in composition. Mafic minerals generally have a higher density than felsic minerals and therefore, the oceanic crust is heavier.
Which layer in the earth is similar to the composition of granite?
the Continental Crust
What composition is earths crust?
oceanic crust is made of basalt while continental crust is made of silica rich rocks like granite.
What is composition of the crust under the continents?
continental crust is made of granite and it's high in silica. I had for homework. Hope that helped!!
What is crusts composition?
rocks
What is the composition of the crust under the continents How do you know?
Continental crust is generally high in silica. You may also know that the crust is likely to be made of granite. Hope that helped ;)
How oceanic crust different?
Oceanic and Contintental crust are different in composition as well as size and density Continental- granitic/50-100km thick Oceanic- basaltic/ up to 10km thick Oceanic crust is more dense making it subduct under continental crust
Is the theory of the continental drift true?
Continental Drift is an obsolete name for the theory of Plate Tectonics and yes, it is true. It has been proved in many ways, by comparing the composition of oceanic crust and its ages with that of the continental crust, by plotting the reversals of magnetism in the oceanic crust and many other ways.
What is the composition of ocean crust?
It is mostly composed of basalt, and few other mineral types. It is made mostly of igneous rock, same with 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.
The continental crust has the average composition of what?
Granite. Most of the crust is composed of granite. Feldspar is the most common mineral in the earth's crust.Silicon, (Si) and Alluminium, (Al).
