How is ozone important for us?
Why is Ozone Layer important? Ozone protects the Earth from harmful ultraviolet (UV) rays from the Sun. Without the Ozone layer in the atmosphere, life on Earth would be very difficult. Plants cannot live and grow in heavy ultraviolet radiation, nor can the planktons that serve as food for most of the ocean life.
How is ozone important for us Class 7?
The importance of ozone is defined by the fact that it protects the earth from harmful ultraviolet rays from the sun. The ozone layer is found in the upper regions of the stratosphere where it protects the earth from the harmful ultraviolet rays of the sun. These radiations can cause skin cancer in humans.
Why is ozone in the stratosphere important?
Stratospheric ozone is a naturally-occurring gas that filters the sun’s ultraviolet (UV) radiation. Absorption of UV-B by ozone in the stratosphere reduces the amount of UV-B reaching the earth’s surface and also generates heat that plays a role in maintaining the temperature structure of the atmosphere.
Is there a dynamic steady state of ozone in the stratosphere?
Ozone forms by combining an oxygen atom with an oxygen molecule. B. There is a dynamic steady state of ozone in the stratosphere. UV radiation will dissociate ozone into an oxygen atom and an oxygen molecule.
What is the significance of ozone in the stratosphere quizlet?
Stratospheric ozone is important in the earth system because it absorbs ultraviolet radiation from the sun, protecting life on earth. Ozone is a relatively rare and unstable molecule composed of three oxygen atoms O3.
How is ozone being maintained in the higher level of atmosphere?
The ozone layer is continuously formed in the atmosphere because of the action of UV rays on molecular oxygen. The high-energy UV radiations break down O2 molecules present in upper layers of the atmosphere into nascent oxygen. Then, this free oxygen atom combines with an oxygen molecule to form ozone.
Why is ozone so high in the atmosphere?
This happens when pollutants emitted by cars, power plants, industrial boilers, refineries, chemical plants, and other sources chemically react in the presence of sunlight. Ozone is most likely to reach unhealthy levels on hot sunny days in urban environments, but can still reach high levels during colder months.
