Talk:Ozone layer
This is an old revision of this page, as edited by DavidB4 (talk | contribs) at 22:40, March 8, 2017. It may differ significantly from current revision.
UVA causes sunburn, UVB causes skin damage, and UVC cuts right through most protections (clothing, sun block, etc. and damages sub-dermal tissue and DNA. UVC is the weakest, UVA is s little stronger, and UVC is the strongest. Does the ozone layer really only block UVB? UVB can be blocked by a sheet of paper, so I expect the ozone does more than that. Does anyone know?
