Scattering causes solar rays to deviate from their original path as they interact with particles or molecules in the atmosphere, leading to a diffuse distribution of sunlight. This can result in a decrease in the intensity of light reaching the Earth's surface in some cases.
The tropics.
Vertical rays of the sun are more intense than slanting rays because they strike the Earth's surface more directly, concentrating the solar energy over a smaller area. In contrast, slanting rays spread the same amount of energy over a larger surface area, resulting in lower intensity. This direct angle also means that vertical rays have to pass through less atmosphere, reducing scattering and absorption. Consequently, areas receiving vertical sunlight experience higher temperatures and greater solar energy.
While the gases in the atmosphere are relatively thin compared to solid or liquid substances, they still play a significant role in absorbing and scattering solar radiation. The atmosphere blocks and absorbs certain wavelengths of solar rays, particularly ultraviolet (UV) radiation, thanks to ozone and other components. This protective mechanism helps shield the Earth's surface from harmful radiation, demonstrating that even thin gases can effectively influence solar radiation.
Ozone protects us from harmful UV rays by absorbing and scattering the radiation before it reaches the Earth's surface. Nitrogen plays a minor role in protecting us from harmful sun rays since it mainly acts as a diluent in the atmosphere, helping to reduce the intensity of solar radiation. Carbon dioxide does not directly protect us from harmful sun rays but it contributes to the greenhouse gas effect, which traps some of the sun's heat on Earth.
Yes, the Earth's atmosphere plays a crucial role in protecting us from harmful solar radiation. The ozone layer in the stratosphere absorbs most of the Sun's ultraviolet (UV) rays, shielding us from their harmful effects. Without this protection, life on Earth would be significantly impacted by excessive exposure to solar radiation.
No, not all solar energy intercepted by the Earth arrives as oblique rays. Solar energy reaches the Earth in the form of parallel rays, but the angle at which these rays strike the surface varies based on the Earth's curvature and its axial tilt. This variation causes some regions to receive sunlight more directly (perpendicular rays) while others receive it at an angle (oblique rays). Consequently, the intensity of solar energy varies across different locations and times of the year.
Scattering
The tropics.
Yes, a majority of gamma rays are blocked by the Earth's atmosphere. The atmosphere acts as a shield against the harmful effects of gamma rays by absorbing and scattering them. Only a small fraction of gamma rays from space can penetrate into Earth's atmosphere.
ultraviolet radiation, x-rays, gamma rays......
The process of scattering occurs when small particles and gas molecules diffuse part of the incoming solar radiation in random directions without any alteration to the wavelength of the electromagnetic energy. This factor also causes our sky to look blue because this color corresponds to those wavelengths that are best diffused. If scattering did not occur in our atmosphere the daylight sky would be black.

Yes. Our atmosphere blocks cosmic and solar gamma rays.
By saving power because of sun rays
