How long does the mid-oceanic ridge extend?

The mid-oceanic ridge extends almost 64,000 kilometers, making it the longest mountain range in the world. This undersea chain is formed by tectonic plate movements, specifically where the oceanic plates diverge and magma rises to create new oceanic crust.

The immense length of the mid-oceanic ridge showcases the dynamic processes of plate tectonics, where seafloor spreading can be observed. The ridge is not uniform throughout its length; it features various sections with different geological characteristics, including rift valleys and volcanic activity. The vastness of this underwater mountain range plays a crucial role in ocean circulation and ecosystems, significantly influencing global climate patterns.

This substantial measurement greatly exceeds the lengths suggested in the other options. Understanding the scale of the mid-oceanic ridge is essential for appreciating not only its geological significance but also its impact on oceanography and marine life.
