Which consequence results when magma's slow cooling rate within dikes creates a high viscosity lava that obstructs its own pathway?

💡 Explanation

The formation of lava domes occurs because high viscosity lava solidifies near the vent, obstructing the pathway; viscous lava cannot flow far causing a buildup. Therefore, lava domes form rather than effusive flows because the magma's high silica content increases viscosity.
