Mid ocean ridges the global mid ocean ridge system is the largest single volcanic feature on the earth encircling it like the seams of a baseball.
Mid ocean ridges around the globe are linked by plate tectonic boundaries and the trace of the ridges across the ocean floor appears similar to the seam of a baseball.
It turns out global mid ocean ridges are largest mountain chain on earth.
The mid ocean ridge system thus is the longest mountain range on earth reaching about 65 000 km 40 000 mi.
They wind through more then 40 000 miles of ocean floor making the earth look like it has a.
