Albedo measures surface reflectivity. High-albedo surfaces like snow reflect sunlight to keep regions cold, whereas low-albedo surfaces like oceans and dark soil absorb solar radiation, driving regional heating and climate patterns.

Revise, Reflect, Refine Chapter 13 Question Answer
Albedo represents the proportion of incoming solar radiation reflected by a surface. Bright surfaces such as polar snow and ice possess high albedo (0.80 to 0.90), reflecting most sunlight back into space and cooling planetary poles. Conversely, dark soils, urban asphalt and deep ocean waters possess low albedo, absorbing significant radiant energy, elevating local temperatures and regulating climate dynamics.
