The most recently formed crust of the earth would be found on what type of boundary?

The most recently formed crust of the Earth is typically found at divergent boundaries, where tectonic plates move apart from each other. This process allows magma from the mantle to rise and solidify, creating new oceanic crust. A prime example of this is the Mid-Atlantic Ridge, where new crust is continuously formed as the North American and Eurasian plates separate.
