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

younger
Compared to ocean crust near deep-sea trenches, crust near ocean ridges is generally younger, thinner, and hotter. Ocean ridges are sites of active seafloor spreading where magma rises to create new crust, while deep-sea trenches are associated with subduction, where older, denser crust is pulled back into the mantle. As a result, the crust at ocean ridges is also less dense and more buoyant than the crust found near trenches.
The crust contains the ocean floor and also the continents on Earth.
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.
it is basalt or oceonic 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.
