Describe how albedo affects the Earth’s surface temperature and its climate.
Albedo is the fraction of solar radiation reflected by a surface. Surfaces with high albedo reflect more light and stay cool, while low albedo surfaces absorb more light and heat up quickly.
For instance, snow and ice have a high albedo, reflecting large amounts of incoming solar radiation, which makes polar regions very cold. On the other hand, surfaces like black soil and ocean water have a lower albedo, absorbing more radiation and becoming relatively warmer.
This variation in albedo contributes to the uneven heating of the Earth's surface. This uneven distribution of temperature, along with latitude, drives global winds and ocean currents, ultimately shaping the Earth's climate.
Explanation
The answer directly uses the textbook's definition of albedo and its effect on surface temperature (high albedo reflects more and stays cool, low albedo absorbs more and heats up). It incorporates the specific examples provided in the text, such as snow/ice making polar regions cold and black soil/ocean water being warmer. Finally, it connects surface temperature differences to climate by referencing the text's mention of uneven heating driving global winds and ocean currents.
