Question 4
Describe how albedo affects the Earth’s surface temperature and its climate.
View Answer Hide Answer
  • Albedo is the fraction of sunlight a surface reflects; high-albedo surfaces (snow, ice) reflect most light and stay cool, keeping polar regions cold.
  • Low-albedo surfaces (black soil, ocean) absorb more sunlight and warm up, so changing albedo (e.g. by melting ice or deforestation) can shift regional and global temperatures.
Albedo and Climate High albedo snow and ice reflect light Low albedo dark surfaces absorb high-albedo surfaces stay cool while low- albedo surfaces absorb heat, so albedo shapes the climate.
