mid ocean ridges
New ocean crust is formed at mid-ocean ridges where tectonic plates are diverging (spreading apart).
Ocean crust is formed at seafloor spreading centers. One example of this is the Mid-Atlantic ridge.
No, the mid-ocean ridge is actually where new oceanic crust is formed through volcanic activity. As the crust moves away from the ridge, it becomes older. The oldest oceanic crust is found near the edges of the ocean basins.
Oceanic crust, formed mostly of mafic rocks, or sima, is found on the ocean floor.

Geothermal activity has revealed new characteristics of Earth's crust near Lake Myvatn, Iceland. In places like Iceland, new research has shown volcanoes and hot springs forming as the result of activity between the crust and the mantle.
The reason for this is that the ocean floor is ever changing and is never in the same possition due to current.
Ocean crust is formed through a process called seafloor spreading, where magma rises up at mid-ocean ridges, cools, and solidifies to create new crust. This process is part of plate tectonics, where oceanic plates move away from each other, allowing new crust to form at the ridges.
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.
