When comparing an oceanic crust and a landform crust, the oceanic crust will be much younger. Typically, an oceanic crust is less than 200 million years old.

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

Mid-ocean ridges are the primary landform that occurs in seafloor spreading. These are underwater mountain ranges where tectonic plates are moving apart, allowing magma to rise up and form new oceanic crust.
A mid-ocean ridge is created when plates separate. This landform is characterized by underwater mountain ranges where new oceanic crust is formed from volcanic activity along divergent plate boundaries.

Crust under the oceans is called oceanic crust.
