Final answer:
The youngest crust on Earth is most likely found at the center of a mid-ocean ridge where tectonic plates diverge and new crust is created.
Step-by-step explanation:
The youngest crust on Earth is most likely found at the center of a mid-ocean ridge.
Mid-ocean ridges are underwater mountain ranges where tectonic plates diverge, causing new crust to form through volcanic activity. The magma that wells up from the mantle cools and solidifies, creating new crust. This process is known as seafloor spreading.
As a result, the crust near the mid-ocean ridges is very young, typically less than 200 million years old.
