Which geological feature is an example of diverging plate boundaries?

The Mid-Atlantic Ridge serves as a prime example of diverging plate boundaries, where two tectonic plates are moving away from each other. As these plates separate, magma from the mantle rises to fill the gap, creating new oceanic crust. This process not only leads to the formation of underwater mountain ranges but also contributes to the phenomenon known as sea-floor spreading.

In contrast, the other geological features listed are all associated with convergent plate boundaries, where plates collide. The Andes Mountain Range is a product of the Nazca Plate subducting beneath the South American Plate, resulting in significant mountain building and volcanic activity. The Rocky Mountains, similarly, were formed by the collision and convergence of continental plates. The Alps also arose from the collision of the African Plate with the Eurasian Plate, leading to folding and uplift. Thus, the Mid-Atlantic Ridge uniquely exemplifies the divergent process, showcasing the dynamic nature of Earth's lithosphere.
