Mid-ocean ridge The longest marine mountain range in the world
With an extension of 80,000 km around the ocean, «Mid-oceanic Ridge» is considered the longest mountain range in the world.
This underwater mountain range lies under the middle of the Atlantic Ocean (emerging in Iceland) surrounds Africa, passes through the Indian Ocean, between Australia and Antarctica, and returns north through the Pacific Ocean.
This system of mountains and valleys across the globe resembles the seams on a baseball. It is submerged at a depth of between 3,000 and 5,000 meters below sea level.
A true giant hidden under the waters.
In terms of width, the Mesoatlantic ridge has an extension that occupies approximately 1,500 kilometers in its most important parts, and in terms of the height of its peaks it only exceeds 3,000 meters in the points closest to the surface, so it is light years from the highest mountains on the earth’s surface.
The ridges are limits between tectonic plates in which the plates move away from each other, for this reason they are called «divergent limits».
In expansion zones, when there is a separation of tectonic plates, there is a process of magma outflow towards the surface.
As these expansion zones are under the ocean, this magma or molten rock emerges and solidifies in such a way that it generates a ridge, a mountain range that extends along the edge of the plates.
