Which outcome occurs when gas pressure exceeds constraint in a volcanic dome?

A)Violent explosive eruption occurs
B)Effusive lava flow develops
C)Tephra deposition rapidly declines
D)Caldera collapses instantaneously

💡 Explanation

Violent eruption blasts the dome when gas pressure overcomes viscous drag forming the dome because increased pressure exceeds the crust's strength, therefore causing explosive fragmentation rather than a flow reduction because the dome is blocked.
