Describe how these factors influence the viscosity of magma: silica content, volatile content, and temperature.

silica content- The more silica that is in magma, the more viscous the magma will be due to the strong silica-oxygen bonds.

volatile content- When water is added to the silica-oxygen bonds, the viscosity decreases.

temperature- As the temperature increases, the viscosity also increases
