Which outcome results on a volcanic island undergoing isostatic rebound?

💡 Explanation

Isostatic rebound causes uplift of the island, increasing the land area and therefore expansion of the freshwater lens volume as groundwater replenishes the elevated terrain. This occurs because hydrostatic equilibrium shifts, rather than increased erosion.

• Which outcome results when unimpeded longshore drift encounters a deeply incised river mouth?
• What outcome results when an increase in sediment deposition alters lake bathymetry?
• Which erosional outcome amplifies when river levees artificially constrain channel width?
• Which process drives the formation of island arcs at subduction zones experiencing volatile flux?
• On Mars, which process limits ventifact formation timescales?
• Which consequence results when prolonged tephra fallout occurs?
