WebViscosity is the resistance to flow (opposite of fluidity). Viscosity depends on primarily on the composition of the magma, and temperature. Higher SiO 2 (silica) content magmas have higher viscosity than lower SiO 2 content … WebJul 22, 2024 · The viscosity of a magma is affected by its silica content and temperature. The amount of silica influences the magma’s viscosity in such a way that if the silica content is low the magma would have low viscosity whereas a high content of silica would make the magma more thick and sticky.
