The density of the continental crust typically ranges from about 2.6 to 3.0 grams per cubic centimeter. This variation depends on the composition and thickness of the crust, with granitic rocks generally being less dense than basaltic rocks found in oceanic crust. The average density of the continental crust is often considered to be around 2.7 g/cm³.
Oceanic crust is denser than continental crust. Oceanic crust has a density of about 3 g/cm^3, while continental crust has a lower density of about 2.7 g/cm^3.
Oceanic crust has a higher density compared to continental crust. This is primarily due to its composition; oceanic crust is predominantly made up of basalt, which is denser than the granitic rocks that make up much of continental crust. As a result, oceanic crust typically ranges from about 7 to 10 kilometers in thickness, while continental crust can be much thicker but is less dense overall.
The primary reason continental crust remains above oceanic crust is its lower density. Continental crust is primarily composed of lighter, less dense rocks like granite, while oceanic crust is denser, made mostly of basalt. This difference in density causes the buoyant continental crust to "float" on the denser oceanic crust beneath it, resulting in the continental crust being elevated above sea level.
Oceanic crust is more dense than continental crust.
One major difference between oceanic crust and continental crust is their composition and density. Oceanic crust is primarily composed of basalt and is denser and thinner, averaging about 7 kilometers in thickness. In contrast, continental crust is mainly composed of lighter granitic rocks and is thicker, averaging around 30-50 kilometers. This difference in density contributes to the distinct characteristics of oceanic and continental tectonic plates.

The specific gravity, on average, of continental crust is 2.7. For oceanic crust, it's 2.9.
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.
Granitic rock forms the majority of the continental crust.
No, the density of Earth's crust varies depending on the type of rock and location. Generally, continental crust is less dense than oceanic crust. Continental crust is composed mostly of granite and has an average density of about 2.7 g/cm^3, while oceanic crust, which is mainly basalt, has an average density of about 3.0 g/cm^3.
density
The density of oceanic crust is generally higher than continental crust due to its composition of mostly basaltic rock. This higher density causes oceanic crust to be thinner and denser, leading to its subduction beneath continental crust at convergent plate boundaries.
Oceanic crust is composed of minerals with a higher density than those found in continental crustal rock.
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).
