Is oceanic crust or continental crust deneser?

Oceanic crust is denser than continental crust. This is primarily due to its composition; oceanic crust is mainly made of basalt, which is a denser volcanic rock, while continental crust is primarily composed of lighter granitic rocks. As a result, oceanic crust typically has a density of about 3.0 g/cm³, whereas continental crust averages around 2.7 g/cm³. This difference in density is a key factor in the behavior of tectonic plates and their interactions.
