Answer:
C. Silica
Explanation:
Higher silica increases viscosity. Magmas that have a high silica content will therefore exhibit greater degrees of polymerization, and have higher viscosities, than those with low silica contents.
Silica
Explanation:
Silica: Influences lava viscosity and overall shape of the volcano. Silica molecules form a strong bond that permits entrapment of volcanic gases and promotes explosive volcanic eruptions
