The ozone layer specifically excels at absorbing UV-B radiation (280–315 nm). While it absorbs all UV-C radiation (the most dangerous), UV-B is the wavelength that partially reaches the surface and causes sunburn, skin cancer and cataracts. By absorbing most of ...
All of the listed statements are scientifically accurate. Atmospheric pressure does fluctuate twice daily due to “atmospheric tides.” It is also true that pressure reaches its maximum at sea level because the air is most compressed there. Finally, millibars are ...
