y LUCIUC 2. The viscosity of magma decreases with 3. The property of the material's resistance to flow is ds to increase its ability to flow when it contains dissolved 4​
answer: These bubbles behave like rigid particles, causing an increase in magma viscosity. Stein and Spera [2002] summarized the situation as follows: when Ca > 10, magma viscosity is decreased by bubbles; however, when Ca < 0.1, it is increased
