Why do large amounts of ozone exist high in the atmosphere?
Stratospheric ozone is formed naturally through the interaction of solar ultraviolet (UV) radiation with molecular oxygen (O2). The “ozone layer,” approximately 6 through 30 miles above the Earth’s surface, reduces the amount of harmful UV radiation reaching the Earth’s surface.
Where is the most ozone concentrated in the atmosphere?
the stratosphere
Most atmospheric ozone is concentrated in a layer in the stratosphere, about 9 to 18 miles (15 to 30 km) above the Earth’s surface (see the figure below). Ozone is a molecule that contains three oxygen atoms.
How is ozone formed 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 the presence of ozone in the atmosphere 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. With a weakening of the Ozone Layer shield, humans would be more susceptible to skin cancer, cataracts and impaired immune systems.
Why is ozone generally not found in the lower part of the atmosphere?
Up in the higher reaches of the atmosphere, ozone is constantly being created due to all that sunlight constantly slamming into oxygen molecules and breaking them apart. That’s why the ozone concentration is higher up there than it is back on Earth.
Where is ozone in the atmosphere?
Ozone occurs both in the Earth’s upper atmosphere and at ground level. Ozone can be good or bad, depending on where it is found. Called stratospheric ozone, good ozone occurs naturally in the upper atmosphere, where it forms a protective layer that shields us from the sun’s harmful ultraviolet rays.
How is ozone formed in lower atmosphere?
Ozone is formed in the lower atmosphere primarily by nitrogen oxides (NOx) reacting with volatile organic compounds (VOCs) on warm, sunny days. Nitrogen oxides are released into the atmosphere as a by-product of any combustion.
How is ozone formed in the atmosphere Class 10?
CBSE NCERT Notes Class 10 Biology Our Environment. Ozone is a molecule formed by three atoms of oxygen. The UV radiations split apart some molecular oxygen (O2) into free oxygen (O) atoms which then combine with the molecular oxygen (O2) to form ozone (O3).
What is ozone how is it formed in the atmosphere explain with equation?
Ozone is created in the atmosphere when the sun’s rays split oxygen molecules into single atoms. These atoms combine with nearby oxygen to form a three-oxygen molecule, called ozone. Explanation: O+O2= O3. Oxygen with one molecule when combined with other oxygen having two molecules gives you OZONE.
What is the important function of presence of ozone in Earth’s atmosphere Brainly?
Ozone Layer blocks the shortwave ultraviolet radiation wavelength that passes through it. This property give it an important function in protecting the biosphere. If the Ozone Layer were not present then the ionizing ultraviolet rays would destroy most of all the life on earth.
Why is ozone good in the stratosphere?
Stratospheric ozone is “good” because it protects living things from ultraviolet radiation from the sun. Called stratospheric ozone, good ozone occurs naturally in the upper atmosphere, where it forms a protective layer that shields us from the sun’s harmful ultraviolet rays.
How does the ozone layer affect the atmosphere?
Atmospheric ozone has two effects on the temperature balance of the Earth. It absorbs solar ultraviolet radiation, which heats the stratosphere. It also absorbs infrared radiation emitted by the Earth’s surface, effectively trapping heat in the troposphere.
