Mid-oceanic ridge

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. Most mid-ocean ridges of the world are connected and form the Ocean Ridge, a global mid-oceanic ridge system that is part of every ocean, making it the longestmountain range in the world. The continuous mountain range is 65,000 km (40,400 mi) long (several times longer than the Andes, the longest continental mountain range), and the total length of the oceanic ridge system is 80,000 km (49,700 mi) long.
