Which consequence results when highly silicic magma erupts effusively?

💡 Explanation

Lava domes form because high-silica magma has very high viscosity from increased polymerization; therefore, lava accumulates near the vent instead of flowing freely downhill, rather than producing broad flows because lower-silica magmas have markedly lower viscosity.
