Divergent boundaries can create massive fault zones in the oceanic ridge system.

The northern and central ridge systems are divided by Dark Hollow, a narrow valley that spans the entire park.

The mid-ocean ridge systems form new oceanic crust.

Although the ridge system runs down the middle of the Atlantic Ocean, the ridge is located away from the center of other oceans.

The mid-ocean ridges of the world are connected and form a single global mid-oceanic ridge system that is part of every ocean.

The mid-oceanic ridge system is the longest mountain range in the world.

The ridge system is only a few hundred meters in height, with a width that averages 5 km but is thicker to the southeast.

Salpausselkä is an extensive ridge system left by the ice age in Southern Finland.

The ridge system is heavily cratered, indicating that it is ancient.

Hydrothermal circulation in the oceans is the passage of the water through mid-oceanic ridge systems.
