Which of the following types of radiations is absorbed by the upper layer of the atmosphere?

The best answer is (B) Ultraviolet. ☀️ The upper layer of the atmosphere, specifically the ozone layer, absorbs most of the Sun’s harmful ultraviolet (UV) radiation. Infrared (IR) radiation mostly reaches the lower atmosphere and the Earth’s surface, adding heat. Radio waves are transmitted through the atmosphere almost entirely, which is why we can receive satellite signals. Visible light passes through the atmosphere mostly, which is why we can see sunlight.Thus, the ozone layer functions as Earth’s sunscreen by protecting us from UV rays.
