← GeographyWhich phenomenon forms stepped topography within glacial lakes?
A)Isostatic rebound and sediment loading✓
B)Varve deposition altered by faulting
C)Kettle hole collapse under thaw
D)Moraine damming by ice advance
💡 Explanation
Stepped features appear due to isostatic rebound following deglaciation and subsequent sediment loading, because the crust readjusts in stages exposing previous lakebeds; therefore, the land slowly rises rather than having kettle collapse.
