Question

most ultraviolet (uv) rays are deflected or absorbed by the atmosphere, but some of these rays pass easily through the atmosphere and penetrate earths surface. which substance in the atmosphere absorbs most of the ultraviolet rays? chlorofluorocarbon ozone nitrogen water

Explanation:

Ozone (\(O_3\)) in the stratosphere forms a layer that absorbs most of the harmful ultraviolet (UV) radiation from the sun. Chlorofluorocarbons (CFCs) are harmful as they can deplete the ozone layer. Nitrogen (\(N_2\)) makes up about 78% of the atmosphere but does not absorb UV rays significantly. Water (\(H_2O\)) vapor in the atmosphere has other roles like in the water cycle and greenhouse effect but is not the main absorber of UV rays.

Answer:

ozone
