Importance of Ozone Layer
Importance of Ozone Layer What is Ozone Layer? Ozone layer, also known as ozonosphere, region from the upper atmosphere, between 15 and 35 km (9 and 22 miles) above Earth’s surface, that contains relatively high concentrations of ozone molecules(O3). 90 % from the atmosphere’s ozone happens in the stratosphere, the location extending from 1018 km (611 miles) to 50 km (about 30 miles) above Earth’s surface.

The ozone layer effectively blocks all solar radiation of wavelengths under 290 nanometres from reaching Earth’s surface, including certain kinds of ultraviolet (Ultra violet) radiations. Importance of Ozone Layer Protection of earth from harmful radiation : The ozone layer is essential for that safety and health of existence on the planet since it protects us from dangerous ultraviolet (Ultra violet) radiation. Ultra violet light is really a group of the spectrum of sunshine. We can't see Ultra violet sun rays, they're very intense, may cause burning, and also over time can damage the skin which can lead to cancer. Protects from UV Rays The ozone layer protects us from 97% from the dangerous results of Ultra violet sun rays. Consider a period when you or somebody spent a lot of time out under the sun and also got a sunburn. Now consider the truth that individuals burns are simply 3% of the they could have been if there wasn't any ozone layer to remove the majority of the Ultra violet sun rays. Reduces Temperature Among the strangest reasons for Ultra violet radiation is “it burns the skin even though you may not feel hot.” If there's direct contact involving the skin and sunlight, you may be burned by Ultra violet sun rays. For this reason we want the ozone layer. Without them, we couldn’t go outdoors without special suits even on cloudy days. For this reason it's so essential that we safeguard our precious ozone layer. Polar Ice Shifting and Ozone layer You might have heard that the an hole within the ozone layer had once created within the atmosphere. Within the 1980s, because of manufacturing processes and residential utilization of CFCs, an opening within the ozone layer covering millions of square miles above Antarctica had created. For a long time, ozone depletion was regarded as probably the most critical ecological issue. THANKS Image Credit:www.askideas.com
