Ozone.<\/p>\n<p>Ozone is a gas that is found in the Earth&#8217;s atmosphere. It is made up of three oxygen atoms, and it is very good at absorbing ultraviolet radiation from the sun. This is important because ultraviolet radiation can damage DNA and cause skin cancer. Ozone helps to protect us from this damage by absorbing the ultraviolet radiation before it reaches the surface of the Earth.<\/p>\n<p>Carbon dioxide, ammonia, and <div class=\"telegram-channel-container\">\r\n        <a href=\"https:\/\/t.me\/pscnotes2025\" target=\"_blank\" class=\"telegram-channel-button\">\r\n            <span class=\"telegram-icon\">\r\n                <svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 496 512\">\r\n                    <path fill=\"white\" d=\"M248,8C111,8,0,119,0,256s111,248,248,248s248-111,248-248S385,8,248,8z M362,177L320,367c-3,14-10,18-20,14l-56-41l-27,26 c-3,3-5,5-10,5l4-63L323,196c5-5-1-7-8-3l-98,62l-42-13c-9-3-10-9,2-14l162-63C351,160,365,164,362,177z\"\/>\r\n                <\/svg>\r\n            <\/span>\r\n            Join Our Telegram Channel\r\n        <\/a>\r\n    <\/div> chlorine are all gases that are also found in the Earth&#8217;s atmosphere, but they do not absorb ultraviolet radiation as well as ozone does.
