Why does continental crust stay on top of the oceanic crust?
The continental crust is less dense than the oceanic crust, so the oceanic crust sinks. The earth has layers based on the density of the mineral assemblages. Solid iron core, liquid outer core, heterogenic graded mantle mineral assemblages.... the continental crust and oceanic crust are a part of the near surface of the grading with even the atmosphere grading outwards. The Continental crust is made up of less dense mineral assemblages primarily silicon rich granites and associated sediments. the Oceanic crust is made up of heavier elements like magnesium and Iron in the form of basalts and gabbros.
Which type of crust is primarily made of basalt and is more dense?
Continental is made mostly of granite. Oceanic is made mostly of basalt and gabbro.
How many tectonic plates are made of only oceanic crust?
how many tectonic plates are made of oceanic crust
What are the 3 elements are the oceanic crust made of?
The oceanic crust is made out of mostly basalt.
Where does the oceanic crust begin?
The continental shelf is normally made out of continental crust, the oceanic crust begins at the base of the continental rise. However in most places the oceanic crust near the continental margins is covered by continental sediments (eroded form the continents) carried down onto the Oceanic planes by deep sea canyons running off the continental rises.
Is the continental crust a solid liquid or gas?
The oceanic crust itself is made of solid rock.
What is crusts composition?
rocks
Is the crust made out of a liquid or a solid?
No, The crust is solid. The oceans just happen to sit on top of it.
The two types of crust?
Oceanic and Continental crust. Oceanic crust is made of basalt. Continental crust is made of granite

Which rock makes continental and oceanic crust?
Continental crust is made of granite. Oceanic crust is made of basalt.
Which type of crust is primarily made of basalt and is more dense?
Continental is made mostly of granite. Oceanic is made mostly of basalt and gabbro.
What is the difference between contiental crust and oceanic crust?
Continental crust is on top of the oceanic crust Continental crust is made of granite whereas oceanic crust is made of basalt Continental crust is partly above sea level and partly below whereas oceanic crust is always below sea level.
What is the oceanic layer of Earth made of?
oceanic crust
What is made at oceanic oceanic crust?
i genous rock
What accounts for the difference between the oceanic crust and continental crust?
The oceanic crust is made up of basalt while continental crust is made up of mostly granite.
Are oceanic plates only made up of oceanic crust?
yes but oceanic crust is younger than continental crust because of deep sea trenches
