Which crustal deformation results when high-viscosity lava cools within volcanic vents?

💡 Explanation

Lava domes result from the accumulation of viscous lava that cannot flow far— viscous lava solidifies within the vent causing uplift because pressure from magma forces the cooled lava upwards. Shield volcanoes form from fluid lava, therefore, that spreads out rather than accumulates.
