WebNov 10, 2024 · It formed and evolves as a result of spreading in Earth’s lithosphere—the crust and upper mantle—at the divergent boundaries between tectonic plates. The vast majority of volcanic activity on the planet occurs along the mid-ocean ridge, and it is the place where the crust of the Earth is born. 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. WebJan 11, 2024 · In the oceans, plates move apart at mid-ocean ridges. Lava rises upward, erupts, and cools. Later, more lava erupts and pushes the original seafloor outward. This is seafloor spreading. Seafloor spreading forms new oceanic crust. The rising magma causes the ridge to be buoyant. This is why there are mountain ranges running through the oceans. centura women\\u0027s health orchard
