Mar 21, 2025 · UVB is particularly effective at damaging DNA. It is a cause of melanoma and other types of skin cancer. It has also been linked to damage to some materials, crops, and marine organisms. The ozone layer protects the Earth against most UVB coming from the sun.

Jan 14, 2023 · What's happened to the ozone layer? The ozone layer has been damaged over many years, in part due to chemicals called CFCs. It stands for chlorofluorocarbons, which are made up of chlorine,...

Mar 22, 2022 · Ozone is mostly found in the stratosphere, a layer of the atmosphere between six and 30 miles (10-50 km) above the Earth's surface. This ozone layer forms an invisible protective shield over...

Ozone layer depletion is the thinning of the ozone layer that protects the earth from the harmful UV radiations. Explore the causes, effects, and solutions to ozone layer depletion only at BYJU'S.

Mar 25, 2025 · Learn about how international action under the Montreal Protocol has helped to reverse ozone layer depletion. The ozone layer hole over the Antarctic is expected to disappear by mid-century.

Jan 10, 2023 · What is the ozone layer, and why does it matter? Human activity has damaged this protective layer of the stratosphere, but scientists say the ozone layer is on track for recovery.

Ozone depletion and the ozone hole have generated worldwide concern over increased cancer risks and other negative effects. The ozone layer prevents harmful wavelengths of ultraviolet (UVB) light from passing through the Earth's atmosphere.

Mar 19, 2025 · Ozone depletion, gradual thinning of Earth’s ozone layer caused by the release of chemical compounds containing gaseous chlorine or bromine from industry and other human activities. The thinning is most pronounced in the polar regions, especially over Antarctica.

Mar 13, 2023 · The ozone layer absorbs 97% to 99% of the sun’s incoming ultraviolet radiation (UV-B). This is fundamental to protecting life on Earth’s surface from exposure to harmful levels of this radiation, which can damage and disrupt DNA.

Dec 20, 2024 · Specifically, ozone absorbs harmful ultraviolet B (UV-B) radiation from the sun, which can cause cancer and cataracts in humans, and upsets biogeochemical cycles. Ozone’s beneficial effects are especially impressive given how little ozone actually sits between the sun and Earth’s surface.
