WebViscosity is the resistance to flow (opposite of fluidity). Viscosity depends on primarily on the composition of the magma, and temperature. Higher SiO2 (silica) content magmas have higher viscosity than lower SiO2 content magmas (viscosity increases with increasing SiO2 concentration in the magma). 27. what are top two composition of magma WebShield volcanoes have low slopes primarily because. the low viscosity of basaltic magma allows it to flow downhill for long distances. Volcanic mudflows (lahars) are common on …
