← GeographyWhich mechanism inhibits stream formation downstream when continental ice sheets melt?
A)Isostatic rebound effects reduced geopotential✓
B)Reduced albedo causes increased evaporation
C)Cryoconite holes increase surface absorption
D)Increased infiltration sustains shallower acquifers
💡 Explanation
Isostatic rebound causes land uplift because the removal of the ice sheet's mass reduces the downward force, therefore flattening regional geopotential gradients; because of it, streams drain into the sea less effectively, rather than increasing evaporation.
