After effusive lava eruptions decrease, which outcome results from increased dissolved silica content?

💡 Explanation

Rhyolitic lava domes form because higher silica increases viscosity, inhibiting lava flow; therefore, sticky lava piles up near the vent, rather than flowing to create shield volcanoes. Magma fragmentation does not occur.
