WebMagma is created at mid-ocean ridges via decompression melting. Strong convection currents cause the solid asthenosphere to slowly flow beneath the lithosphere. The upper part of the lithosphere (crust) is a poor heat conductor, so the temperature remains about the same throughout the underlying mantle material.

"WebMid-ocean ridges and spreading zones are home to hydrothermal vents. Hydrothermal vents in the ocean are analogous to geysers and hot springs on continents where groundwater percolates up to 2 km below the surface to areas that are very hot. The resulting boiling water and steam rush to the surface. " - How does mid ocean ridges form

WebMay 11, 2024 · How are Mid-Ocean Ridges formed? They occur along the divergent plate boundaries, where a new ocean crust is formed due to the spreading of tectonic plates. As they grow apart, the molten rock beneath the earth’s crust rises to the seafloor through cracks generating significant volcanic eruptions containing lava and basalt. 4. WebMid-ocean ridges are geologically important because they occur along the kind of plate boundary where new ocean floor is created as the plates spread apart. Thus the mid-ocean ridge is also known as a "spreading …
