The ozone layer is located in the what
WebbOzone In the stratosphere, ozone is created primarily by ultraviolet radiation. When high-energy ultraviolet rays strike ordinary oxygen molecules (O 2 ), they split the molecule into two single oxygen atoms, known as atomic oxygen. A freed oxygen atom then combines with another oxygen molecule to form a molecule of ozone. Webb18 apr. 2024 · Rowland, a professor of chemistry at the University of California, Irvine, and Molina, a postdoctoral fellow in Rowland’s laboratory, had shown that chlorofluorocarbons—CFCs—could destroy ozone, a molecule made up of three oxygen atoms, O 3, in Earth’s stratosphere. That stratospheric ozone absorbs ultraviolet …

WebbPSCs appear in the lower stratosphere near the poles in winter. They are found at altitudes of 15 to 25 km (9.3 to 15.5 miles) and form only when temperatures at those heights dip below -78° C. They appear to help cause the formation of the infamous holes in the ozone layer by "encouraging" certain chemical reactions that destroy ozone. Webb10 nov. 2024 · In the 1980s, a team of scientists shocked the world when they detected a hole in the layer. In 1977, 24-year-old Jonathan Shanklin saw an advert for a job at British Antarctic Survey (BAS), which read: Wanted: physicist with an interest in meteorology and programming skills. Feeling he ticked the boxes, Shanklin applied and was offered the role.
