Why is the ozone layer only formed in the stratosphere?
Statement 1: Ozone layer present in the stratosphere protects the living organisms from harmful UV rays coming from the sun by absorbing nearly all of them. Statement 2: Ozone formed in the troposphere by photochemical reactions as a result of human activities which is harmful to all living organisms. Q.
Why ozone is not formed below stratosphere?
Because the ozone absorbs the higher-energy UV photons, no significant amount of ozone forms in the lower part of the atmosphere.
Why ozone layer is above the atmosphere?
The ozone layer is the common term for the high concentration of ozone that is found in the stratosphere around 15–30km above the earth's surface. It covers the entire planet and protects life on earth by absorbing harmful ultraviolet-B (UV-B) radiation from the sun.
Why is ozone good in the stratosphere and bad in the troposphere?
Stratospheric ozone is “good” because it protects living things from ultraviolet radiation from the sun. Ground-level ozone, the topic of this website, is “bad” because it can trigger a variety of health problems, particularly for children, the elderly, and people of all ages who have lung diseases such as asthma.
In which layer of the atmosphere is good ozone found?
the stratosphereIn the stratosphere, which extends from about 10 to 50 km above the Earth's surface, ozone is 'good' as it protects life on Earth from the sun's ultraviolet rays.
In which atmospheric layer is the ozone formed?
the stratosphereOzone is naturally produced in the stratosphere by a two- step reactive process. In the first step, solar ultraviolet radiation (sunlight) breaks apart an oxygen molecule to form two separate oxygen atoms.
Is ozone present in troposphere?
About 10% of atmospheric ozone is in the troposphere, the region closest to Earth (from the surface to about 10–16 kilometers (6–10 miles)). The remaining ozone (about 90%) resides in the stratosphere between the top of the troposphere and about 50 kilometers (31 miles) altitude.
Which layer of Earth's atmosphere is home to the ozone layer?
StratosphereStratosphere. Located between approximately 12 and 50 kilometers (7.5 and 31 miles) above Earth's surface, the stratosphere is perhaps best known as home to Earth's ozone layer, which protects us from the Sun's harmful ultraviolet radiation.
