it is basalt or oceonic crust
Ocean crust is denser
The Earth's crust is thinner than the ocean floor because the oceanic crust is formed at mid-ocean ridges where heat from the mantle creates new crust through volcanic activity. This process creates younger, hotter, and thinner crust in the ocean compared to the older and thicker continental crust.
Crust under the oceans is called oceanic crust.

Oceanic crust is the part of Earth's lithosphere that surfaces in the ocean basins.

The ocean floor is mainly composed of basaltic crust known as oceanic crust. This crust is thinner and denser than continental crust and is formed through volcanic activity at mid-ocean ridges.
New ocean crust is formed at mid-ocean ridges where tectonic plates are diverging (spreading apart).
The crust beneath the ocean is called oceanic crust. It is thinner and younger than continental crust, primarily composed of basaltic rock formed at mid-ocean ridges through volcanic activity.
