How does magma change into lava
WebMagma composition impacts nearly everything about a volcano, with viscosity of the melt being one of the most important factors that determines eruption dynamics, and even the shape of a volcanic edifice. Viscosity is the internal friction, or resistance to flow—or how “thick and sticky” or “thin and runny” a lava is. WebAs it moves toward the surface, and especially when it moves from the mantle into the lower crust, the hot magma interacts with the surrounding rock. This typically leads to partial melting of the surrounding rock …
