The ozone layer is the phrase used to refer to the high concentration of ozone found in the stratosphere, approximately 15–30 kilometers above the earth’s surface, and is located in the stratosphere. It preserves life on earth by absorbing damaging ultraviolet-B (UV-B) radiation from the sun, which is emitted by the sun and covers the whole globe.

Where is the ozone hole located above Earth?
Earth’s natural sunscreen, which is composed of both ground-based and satellite observations, began to deteriorate drastically over the South Pole in the early 1980s, as scientists discovered using a combination of ground-based and satellite data. The ozone hole is a term that refers to the depletion of the ozone layer over Antarctica that has developed through time.
Where does the ozone layer end?
The temperature of the stratosphere, which is the layer of the atmosphere between approximately 10 km and approximately 50 km height, has a direct relationship with ozone depletion. This is due to the fact that polar stratospheric clouds, which play a significant part in the chemical breakdown of ozone, can only develop at temperatures below -78°C, making them unable to form at higher temperatures.
Where does the ozone layer start?
The vast majority of ozone (about 90 percent) is contained inside a layer that begins between 6 and 10 miles (10 and 17 kilometers) above the Earth’s surface and extends up to around 30 miles (48 kilometers) (50 kilometers). The stratosphere is the name given to this area of the atmosphere. The ozone layer is the term used to describe the ozone present in this region.
Is there still an ozone hole?
It is customary to measure the ozone hole by observing a decrease in the total column ozone over a certain place on the Earth’s surface. NASA said in 2017 that the ozone hole has shrunk to its smallest extent since 1988 as a result of warm stratospheric temperatures. Around the year 2070, it is predicted to begin to recover.
Has the ozone hole closed?
According to the World Meteorological Organization (WMO), the Antarctic ozone hole, which was one of the deepest and greatest gaps in the ozone layer in the previous 40 years, has been closed as of January 6, 2021. The same weather variables were also responsible for the record Arctic ozone hole that occurred in 2020, which has already been closed.
What will happen if the ozone layer is destroyed?
The depletion of the ozone layer results in increasing amounts of ultraviolet light at the Earth’s surface, which is harmful to human health. Increases in some forms of skin cancer, eye cataracts, and immune deficiency problems are among the negative consequences of the drug.
Which gas is responsible for ozone hole?
When chlorofluorocarbons (CFCs) and halons—gases that were formerly prevalent in aerosol spray cans and refrigerants—are released into the atmosphere, ozone depletion occurs (see details below).
Can ozone be found near the surface of the earth?
Ozone is found largely in two sections of the atmosphere: the troposphere and the stratosphere. The troposphere contains around 10% of the total ozone in the atmosphere, which is the area closest to the Earth (from the surface to approximately 10–16 kilometers (6–10 miles).
Which layer is rich in ozone?
The majority of the ozone in the atmosphere is concentrated in a layer in the stratosphere, approximately 9 to 18 miles (15 to 30 kilometers) above the Earth’s surface (see the figure below). Ozone is a molecule made up of three oxygen atoms, and it is a gas. In the stratosphere, ozone molecules are continually being created and destroyed at any given point in time.
What is the hottest layer of the atmosphere?
The thermosphere is commonly referred to as the “hot layer” of the atmosphere because it has the hottest temperatures found anywhere in the atmosphere. The temperature rises with altitude until it reaches the predicted peak of the thermosphere at 500 kilometers. Temperatures in this layer can reach as high as 2000 K (1727 oC) when the sun is shining brightly (Wallace and Hobbs 24).
Who invented ozone layer?
This group of single oxygen atoms joins forces with adjacent oxygen to produce the trioxygen molecule known as Ozone. Who was the person who discovered the Ozone Layer? It was the French physicists Charles Fabry and Henri Buisson that made the discovery of the Ozone Layer in 1913.
How much of our ozone layer is left?
Since the late 1970s, the amount of ozone in the atmosphere has decreased by an average of roughly 4% on a global scale. Extremely severe seasonal reductions have been seen over around 5% of the Earth’s surface, particularly near the north and south poles, and they have been referred to as “ozone holes.”
How big is the ozone hole now?
After reaching a record size of 9.6 million square miles (24.8 million square kilometers) this year, NASA satellite studies indicated that the ozone hole had achieved its greatest extent – nearly the size of North America – before beginning to decrease in mid-October.
Can you make ozone?
Ozone is naturally formed by specific types of chemical reactions in the environment. It is less well recognized, however, that ozone may be created artificially and utilized for water treatment purposes. Ozone generators are devices that artificially produce ozone through the use of extremely high voltages or ultraviolet radiation.
