← GeographyWhich feedback results from ice sheet melting exposing land?
A)Reduced albedo enhancing solar absorption✓
B)Increased vegetation accelerating evapotranspiration
C)Increased surface pressure suppressing subduction
D)Higher erosion rates mitigating isostatic rebound
💡 Explanation
Reduced albedo is the result; exposed darker land absorbs more solar radiation, because less is reflected; this increased absorption increases regional temperatures, leading to further melting, therefore accelerating rather than mitigating warming unlike increased evapotranspiration.
