Which volcanic outcome develops due to isostatic rebound?

A)Caldera lake fills with meltwater
B)Pyroclastic flow ignimbrite sheet forms
C)Laccolith forms shallow intrusion
D)Shield volcano flank erupts vog

💡 Explanation

After a glacial ice sheet vanishes, the pressure decreases; therefore, isostatic rebound leads to land uplift, which alters the local water table, triggering caldera lake refilling with meltwater rather than sheet flow because rebound impacts hydrogeology, not eruption style.
