  2. Albedo
  3. Convection
  4. Refraction

Correct answer and explanation

Correct answer: Albedo

Explanation: āœ… Correct Answer: B) Albedo šŸ“š Explanation: Albedo is the measure of the reflectivity of a surface, expressed as the ratio of reflected radiation to incident radiation. Fresh snow has a high albedo (reflecting most sunlight), while dark forests or oceans have a low albedo. The Earth's average albedo is approximately 0.30, which plays a crucial role in regulating the planet's temperature.
