Mid-Ocean Ridges

The mid-ocean ridge is a continuous chain of volcanoes on the ocean floor where lava erupts and the crust of the Earth is created. Nearly every day, somewhere on the crest of the mid-ocean ridge, there is likely to be an eruption of lava or an intrusion of magma that builds the ocean crust.
