GENERAL KNOWLEDGE

Detailed explanation-1: -Bond albedo, defined as the fraction of the total incident solar radiation reflected by a planet back to space, is a measure of the planet’s energy balance.

Detailed explanation-2: -The fraction of the incoming solar energy scattered by Earth back to space is referred to as the planetary albedo. This reflected energy is a fundamental component of the Earth’s energy balance, and the processes that govern its magnitude, distribution, and variability shape Earth’s climate and climate change.

Detailed explanation-3: -The measurement of Earth’s albedo is known as Terrestrial Albedo. The Terrestrial Albedo of Earth around 0.31 which is about two-thirds of the solar radiation reaching the Earth. This figure (0.31) is dependent on many factors like an ocean, forest, clouds, deserts etc.
