Where are the most recently formed parts of the Earth's crust typically located?

The most recently formed parts of the Earth's crust are typically found at mid-ocean ridges. This is because mid-ocean ridges represent divergent tectonic plate boundaries where two plates are moving apart. As the plates separate, magma from the mantle rises to fill the gap, leading to the formation of new oceanic crust. This process is continuous, meaning that the crust is actively being created at these locations.

Mid-ocean ridges are significant geological features that traverse the ocean floor and are the center of seafloor spreading. As the ridges extend across the oceans, they account for a substantial portion of the newly formed crust on Earth. In contrast, while new crust can also form near tectonic plate boundaries through other processes, it is at mid-ocean ridges that we see the clearest and most direct evidence of new crust being formed continuously.
