WitrynaHeat transfer to the plate from the hot magma and from the latent heat of crystallization may also thin and weaken the plate in a bottom-up process. The edge of the stretched and unstretched zone produces steep boundaries at the lithosphere-asthenosphere boundary, as seen in Figs. 2 and 3. Enhanced melting, therefore, may occur along … WitrynaMagma is created at mid-ocean ridges via decompression melting. Strong convection currents cause the solid asthenosphere to slowly flow beneath the lithosphere. The …
