The newest rock on Earth is constantly forming! It's not a single location, but rather a continuous process happening at mid-ocean ridges.

Here's why:

* Mid-ocean ridges are underwater mountain ranges where tectonic plates pull apart.

* This separation allows magma from the Earth's mantle to rise and erupt, creating new oceanic crust.

* As the magma cools and solidifies, it forms igneous rock, specifically basalt, which is the newest rock on Earth.

So, the newest rock on Earth is being created constantly along these mid-ocean ridges, with the most recent formation occurring at the active volcanic vents.
