Solution:
Concept- The depletion of the protective ozone layer in the upper atmosphere (stratosphere) over Earth's polar regions is known as ozone hole.The ozone layer serves as the earth's protective layer. It absorbs the sun's ultraviolet energy. Refrigerators, air conditioning units, sprays, and other appliances emit chlorofluorocarbons (CFCs), which include chlorine, fluorine, and carbon atoms. This molecule reaches the ozone layer, which is located at a high altitude. The very intense photons in the ozone layer react with this molecule, causing ozone to be depleted from the ozone layer.
The ozone hole is a location in the ozone layer where ozone is depleted. Despite the fact that it is a region, it is nonetheless referred to as the hole. This area is located above Antarctica. The ozone hole is the result of increased heat and ozone depletion in the Earth's Polar Regions.
Hence, the answer is ozone hole.
