What percentage of solar radiation is absorbed by the Earth?

The correct answer indicates that approximately 43% of solar radiation is absorbed by the Earth. This percentage is derived from the overall energy balance of the Earth, which receives solar energy from the sun and redistributes it.

When sunlight reaches the Earth, it is either reflected back into space or absorbed by the atmosphere, land, and oceans. The absorption of sunlight contributes to warming the planet, which in turn drives weather patterns, ocean currents, and other climatic phenomena. The figure of around 43% signifies a significant amount of solar energy being utilized in various processes, such as photosynthesis and the heating of the atmosphere and surface, thus playing a crucial role in sustaining life and weather systems.

Additionally, understanding this percentage helps explain concepts such as the greenhouse effect and climate change, as it relates directly to the energy balance and how changes in atmospheric conditions can affect the absorption and radiation of energy. This concept is fundamental in meteorology and climate science, providing insight into how energy from the sun influences weather, climate, and environmental conditions on Earth.
