Oceanic crust is predominately made of basaltic rock with a thin layer of sedimentary rock on top. Continental crust is predominately made of granitic rock, with a thin layer of sedimentary rock covering much of the visible surface.

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.
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.
Oceanic crust is what than continental crust?
Oceanic crust is thinner and denser than continental crust.
What layer of crust averages 25 miles in thickness?
Continental crust.
Differences of the continental crust and oceanic crust?
Thickness - continental = much thickerDensity - oceanic crust is denser than continental, which is why the oceanic crust subducts under the continental at destructive plates boundaries.
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.
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.
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.
Would it be easier to drill through the oceanic crust or the continental crust?
Continental crust is easier. Continental crust is less dense than oceanic crust, which is made of basalt. (Basalt is very dense.)
Why does the oceanic sink beneath continental crust at convergent boundaries?
The continental crust is less dense than the oceanic crust. That's the reason we find that the oceanic crust sinks (subducts) beneath the continental crust.Continental crust is less dense than oceanic crust and so cannot sink below it.
Oceanic crust is lighter than the continental crust?
No, the oceanic crust is denser. That's why the land areas "float" so much higher than the ocean bedrock.
Is the continental crust a solid liquid or gas?
The oceanic crust itself is made of solid rock.
What are two way the continental crust and the oceanic crust are different?
the oceanic crust is thinner, generally5-8 killometers thick, and is made of basalt, but the continental crust is an average of 30 km and is made of granite
Is Mount Kilimanjaro made of continental crust or oceanic crust?
Of course it's continental crust! If it were made of oceanic crust, it would be underwater or some large island starting at the bottom of the ocean floor!
