WebJan 14, 2024 · Ridges form in the mid-ocean when volcanic lava is upwelled and lateral rifting of the ocean crust occurs. They form a rift valley system stretching for over 75,000 km that encircles the Earth. In the hot water from the seafloor, the benthic communities that have evolved to survive by using hydrogen sulfide have become immune to sea air. WebThe Rise is part of the 75,000-kilometer long formation known as the Mid-Ocean Ridge. Like the seam of a baseball, the Ridge winds around the globe from the Arctic Ocean to the Atlantic Ocean, around Africa, Asia and Australia, under the Pacific Ocean and to the west coast of North America.
