The 'Albedo Effect' refers to which of the following phenomena?

  1. The absorption of $CO_2$ by the oceans.
  2. The reflectivity of a surface, such as ice or snow.
  3. The shift in wind patterns due to El Niño.
  4. The rise in global sea level caused by thermal expansion.
Show answer and explanation

Correct answer: The reflectivity of a surface, such as ice or snow.

Albedo is a measure of how much light that hits a surface is reflected without being absorbed. Ice has a high albedo, reflecting most sunlight, while dark ocean water has a low albedo and absorbs more heat.
