1. Lava with low amount of gas as it rises has high viscosity. 2. Volcano can also form where there is stretching and thinning of the crust's interior plates. 3. Lava with less silica content has high viscosity. 4. Equilibrium state of volcano where pressures build. 5. Iraya volcano has the most number of eruptions. 6. The more viscous and thicker the material is, the greater is its resistance to flow. 7. Bubbles move faster in a more viscous liquid such as in syrup. 8. Lava with low amount of gas and high silica content is very viscous. 9. The higher the temperature of magma is, the higher is its viscosity. 10. The heat from inside the Earth is tapped as source of electricity in the geothermal power plant.
