The ozone layer in the stratosphere absorbs a portion of the radiation from the sun, preventing it from reaching the planet's surface. Most importantly, it absorbs the portion of UV light called UVB. UVB is a kind of ultraviolet light from the sun (and sun lamps) that has several harmful effects.Oct 7, 2021
It turns out that the energy levels of electrons in the ozone molecule match the ultraviolet spectrum. Ozone absorbs more than 99 percent of UV-C rays -- the most dangerous portion of the spectrum.Apr 25, 2017
Yes, ultraviolet radiation at Earth's surface increases as the amount of overhead total ozone decreases, because ozone absorbs ultraviolet radiation from the Sun.
The main cause of ozone depletion and the ozone hole is manufactured chemicals, especially manufactured halocarbon refrigerants, solvents, propellants, and foam- blowing agents (chlorofluorocarbons (CFCs), HCFCs, halons).Sep 16, 2020
The stratospheric ozone layer absorbs some, but not all, of these types of UV radiation: UVA: Not absorbed by the ozone layer. UVB: Mostly absorbed by the ozone layer, but some does reach the Earth's surface. UVC: Completely absorbed by the ozone layer and oxygen.
The ozone layer absorbs 97 to 99 percent of the Sun's medium-frequency ultraviolet light (from about 200 nm to 315 nm wavelength), which otherwise would potentially damage exposed life forms near the surface.
Ozone absorbs UV-B radiation from the sun. When an ozone molecule absorbs UV-B, it comes apart into an oxygen molecule (O2) and a separate oxygen atom (O). Later, the two components can reform the ozone molecule (O3).
The ozone layer, our Earth's sunscreen, absorbs about 98 percent of this devastating UV light.May 9, 2011
How does the absorption of ultraviolet radiation by the ozone layer help sustain life? a. This process helps maintain the temperature of the Earth.
Ozone depletion occurs when chlorofluorocarbons (CFCs) and halons—gases formerly found in aerosol spray cans and refrigerants—are released into the atmosphere (see details below).Jul 27, 2017
Chlorofluorocarbons or CFCs are the main cause of ozone layer depletion. These are released by solvents, spray aerosols, refrigerators, air-conditioners, etc. The molecules of chlorofluorocarbons in the stratosphere are broken down by the ultraviolet radiations and release chlorine atoms.
Human activities are the main cause of the depletion of the ozone layer. It occurs due to the excessive use of the man-made chemicals that are bromine and chlorine which release from the man-made compounds such as: Chlorofluorocarbons (CFCs) CFCs (chlorofluorocarbons)
