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

Oceanic crust is mafic.
the oceanic crust is 0.
The youngest parts of the Earth's crust are found in the oceanic crust. This crust is continuously being created at the mid-oceanic ridges.
Oceanic crust is significantly denser.
It is not. The oceanic crust is thinner than the continental crust!
Continental crust is far older than oceanic crust.
