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.
Continental crust is thicker, less dense, and older than oceanic crust. It is primarily composed of granite and sedimentary rocks. In contrast, oceanic crust is thinner, denser, and younger, and is primarily composed of basalt.
No, they are not exactly the same. The continental crust is thicker than the oceanic crust, but the oceanic crust is denser than the continental crust, due to differences in their chemistry.
continental crust is basically land crust, and oceanic is ocean crust on the earth, above the mantle.
- oceanic crust and mantle are mostly basaltic rock
- continental crust is mostly granitic rock

How does the density of oceanic crust differ from that of continental crust?
Oceanic crust is denser than continental crust because it is primarily composed of basalt, which is a mafic rock with a higher density than the felsic rocks that make up continental crust. Additionally, oceanic crust is thinner and younger than continental crust, contributing to its higher density.
What is the difference of continental crust and oceanic crust?
Two differences are that the oceanic crust is more dense than continental, and continental crust is composed mostly of granite, while oceanic is mostly basalt
How do oceanic and continental crust differ?
Oceanic crust is typically thinner, denser, and younger than continental crust. It is primarily composed of basaltic rocks and forms the ocean floor, while continental crust is thicker, less dense, and contains a wider variety of rock types, including granitic rocks. Continental crust forms the continents and is older than oceanic crust.
Which is thicker continental crust oceanic crust?
Continental crust is thicker than oceanic crust. Continental crust can be up to 70 kilometers thick, while oceanic crust is typically around 7 kilometers thick.
Where does the oceanic crust begin?
The oceanic crust begins at the Mid-Ocean Ridge, where tectonic plates are moving apart, allowing magma to rise and solidify, forming new crust. This process of seafloor spreading creates the youngest oceanic crust at the ridge and older crust farther away from it.
How do the oceanic and continental crust differ?
Because the oceanic crust is under water in the ocean and a continental crust is land such as the continents
How are oceanic and continental crust alike and how are they different?
Oceanic and Continental crusts are alike because they both shift and move and grow. They differ by there rock types. Oceanic crust is made up of dense basalt while continental crust is made up of less dense granite.
How does density of the oceanic crust differ from that of continental crust?
Oceanic crust is more dense than continental crust and is comprised of mainly mafic minerals (Mg, Fe), as opposed to continental crust, which is mainly felsic (Al and Si rich).
How does density of oceanic crust differ from that of continental crust?
Oceanic crust is more dense than continental crust and is comprised of mainly mafic minerals (Mg, Fe), as opposed to continental crust, which is mainly felsic (Al and Si rich).

Continental crust forms the continents and is older than oceanic crust.
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 thinner than the oceanic crust?
It is not. The oceanic crust is thinner than the continental crust!
What is older the oceanic crust or the continental crust?
Continental crust is far older than oceanic crust.
Which is thicker continental crust oceanic crust?
Continental crust is thicker than oceanic crust. Continental crust can be up to 70 kilometers thick, while oceanic crust is typically around 7 kilometers thick.
