Which one of the following reflects back more sunlight as compared to other three?
- A.Sand desert
- B.Paddy crop land
- C.Land covered with fresh snow
- D.Prairie land
▶ Answer & Explanation
Correct answer: C. Land covered with fresh snow
Surfaces with high albedo reflect a significant portion of incoming solar radiation back into space. Fresh snow is highly reflective due to its crystalline structure and air pockets, resulting in a very high albedo. Deserts, while bright, absorb more heat. Paddy fields, with water and vegetation, have low albedo, and prairie lands also absorb considerable solar energy.
