Because the oceanic crust is under water in the ocean and a continental crust is land such as the continents
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.
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
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 the thicker of the two: it extends far beneath and above the Oceanic crust.
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.

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.
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).

No, the oceanic crust is denser. That's why the land areas "float" so much higher than the ocean bedrock.

Continental crust is far older than oceanic crust.
It is not. The oceanic crust is thinner than the continental crust!
