The UV rays were entering the surface of earth. This led to discovery of ozone hole.
The ozone was first discovered in late 1800's. This led to discovery of ozone hole.
The discovery of ozone hole led the scientists to search for ways to stop the depletion of ozone layer. Thus various alternated were finded to replace the substances responsible for ozone hole.
The scientists have discovered ozone hole due to technology. Advancements led them to find it.
No, it is not true that ozone is not depleting. Ozone depletion is a well-established scientific fact caused by the release of certain chemicals, such as chlorofluorocarbons (CFCs), into the atmosphere. This depletion has led to the formation of the ozone hole in some regions, particularly over the poles. The warnings about ozone depletion are based on extensive scientific research and observations.
Ozone protects us. It protects from the harmful UV rays of the sun.
Lets clear the first misconception, Mario J Molina did not discover the ozone layer, nor the hole above Antarctica. The ozone layer was discovered in 1913 by the French physicists Charles Fabry and Henri Buisson, and the hole inthe ozone layer by the British Antarctic Survey. What Molina did along with Stuart Rowland was write a scientific paper in 1974 on what damage CFCs were doing the ozone layer back then. Which led to the banning of CFCs, and his Nobel Prize for chemistry in 1995.
The ozone hole is significant because it represents a thinning of the ozone layer in the Earth's stratosphere, which protects us from harmful ultraviolet (UV) radiation. The depletion of ozone is primarily caused by the release of chlorofluorocarbons (CFCs) and other ozone-depleting substances. This has led to increased levels of UV radiation reaching the Earth's surface, posing risks to human health, ecosystems, and agriculture.
discovery of the atom's structure
Ozone layer formation was a natural process in which oxygen was converted to ozone by UV radiations. It is located about 20 to 30 kilometres (12 to 19 mi) above Earth, though the thickness varies seasonally and geographically.
The discovery of radioactivity
Watson and crick and the discovery of the double helix
The Montreal treaty led to to an agreement to stop the production of CFCs (chlorofluorocarbons), which actively destroy the ozone layer.
