Question

Which of the following does not form part of Albedo?

Options

• Clouds

• Ice

• Human beings

• Water bodies

Answer 1

Human beings

Explanation:

Albedo is the amount of solar radiation reflected back by a surface. It varies for different surfaces. Bright white surfaces, like snow and ice, have high albedo, while darker surfaces have low albedo. Clouds, ice, and water bodies all contribute to Earth’s albedo by reflecting solar radiation. Human beings, however, do not contribute to Earth’s albedo in any significant way because they cover an extremely small surface area and do not significantly reflect solar radiation on a global scale.
