Formation composition and viscosity of magma

WebJul 7, 2024 · How does magma viscosity affect a volcano’s topographic profile? The low viscosity of the magma allows the lava to travel down slope on a gentle slope, but as it cools and its viscosity increases, its thickness builds up on the lower slopes giving a somewhat steeper lower slope. Most shield volcanoes have a roughly circular or oval … WebMagma Composition a) Ma c Magma (45-55% SiO2) • higher temperature • Lower SiO2 content • Low viscosity (Runny) b)Intermediate ...
