What type of light does the ozone layer absorb and scatter from the sun?

The ozone layer plays a critical role in protecting the Earth from harmful solar radiation by absorbing and scattering ultraviolet (UV) light. Ultraviolet light, which comes in three types—UVA, UVB, and UVC—is particularly damaging to living organisms. UVC is the most harmful but is completely absorbed by the ozone layer, while some UVB is absorbed, providing a layer of protection that helps reduce risks such as skin cancer and other UV-related health issues.

This effective absorption of ultraviolet light is vital for the preservation of life on Earth, as excessive exposure to UV radiation can lead to severe biological damage. In contrast, the ozone layer is less effective against infrared light and visible light, as these wavelengths are not as harmful to biological systems and thus do not require the same level of protection. X-rays, while also harmful, are not significantly absorbed by the ozone layer, as they primarily interact with much denser materials found lower in the atmosphere. Therefore, the distinction in the types of radiation absorbed by the ozone layer underscores its significance in protecting ecosystems and human health.
