Correct option is C
The Earth's atmosphere and surface reflect a significant portion of the solar radiation that reaches it. This reflected solar radiation is called the albedo. About 30% of the solar radiation is reflected back into space, with the remainder being absorbed by the Earth’s atmosphere and surface. This portion is critical in regulating the Earth's temperature and climate system.
Information Booster:
The albedo effect is crucial in understanding global warming and climate change. A higher albedo (more reflection) tends to keep the planet cooler, while a lower albedo (more absorption) can increase global temperatures.
The Earth’s albedo varies in different regions. Ice and snow-covered areas have a higher albedo, reflecting more solar radiation, while forests and oceans absorb more solar energy.
The Earth’s average albedo is around 0.3, meaning approximately 30% of the solar radiation is reflected back into space.
