Question

The sun emits dangerous UVB nd UVC radiation which can cause sun burns and, ultimately, lead to skin cancer on Earth. What process occurs in Earth's atmosphere that helps protect Earth from some of this radiation?(2 points)

Answer 1

The process that occurs in Earth's atmosphere to help protect the planet from harmful UVB and UVC radiation is primarily the absorption of these ultraviolet rays by ozone (O3) in the stratosphere. The ozone layer absorbs a significant portion of the sun's UV radiation, particularly UVB and UVC, preventing it from reaching the Earth's surface. This absorption helps to shield living organisms from the harmful effects of these types of radiation, such as sunburn and increased risk of skin cancer. Additionally, scattering of UV radiation by atmospheric particles also contributes to reducing the amount of UV radiation that reaches the surface.
