Ozone is formed in upper atmosphere by the reaction of ultraviolet UV radiations on oxygen O2 molecule . The damage to ozone layer is a cause of concern to us as due to its damage more ultraviolet rays reach the earth’s surface causing various health hazards.
How is ozone formed in the upper atmosphere state its importance?
Ozone is formed in the atmosphere when energetic ultraviolet (UV) radiation dissociates molecules of oxygen (O 2 ) into separate oxygen atoms . ... It absorbs the UV radiation emitted from the Sun and prevents them from reaching the surface of the earth.
How is ozone formed in the upper atmosphere?
Stratospheric ozone is formed naturally through the interaction of solar ultraviolet (UV) radiation with molecular oxygen (O2) . ... These reactions have traditionally been viewed as depending upon the presence of heat and sunlight, resulting in higher ambient ozone concentrations in summer months.
How is ozone produced and maintained in the upper atmosphere?
Ozone 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. ... In the over- all process, three oxygen molecules plus sunlight react to form two ozone molecules .
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 (O 2 ) into free oxygen (O) atoms which then combine with the molecular oxygen (O 2 ) to form ozone (O 3 ).
How ozone is created?
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.
What does ozone smell like?
Here are some of the ways the smell of ozone is described:
Like chlorine . A “clean” smell . Sweet and pungent . Like an electrical spark .
How is ozone formed and why is it important in the atmosphere?
How is ozone formed and why is it important to the atmosphere? Ozone is formed throughout the atmosphere in multistep chemical processes that require sunlight . Ozone is a gas in the atmosphere that protects everything living on the Earth from harmful ultraviolet (UV) rays from the Sun.
How is ozone formed in the atmosphere it is poisonous yet useful how?
In the lower atmosphere (the troposphere) near the Earth’s surface, ozone is created by chemical reactions between air pollutants from vehicle exhaust, gasoline vapors , and other emissions. At ground level, high concentrations of ozone are toxic to people and plants.
What is ozone state its importance?
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.
What is the role of ozone in 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 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.
What would happen if there was too much ozone in the atmosphere?
Breathing ozone can trigger a variety of health problems including chest pain, coughing, throat irritation, and congestion . It can worsen bronchitis, emphysema, and asthma. “Bad” ozone also can reduce lung function and inflame the linings of the lungs.
How is ozone gas formed in the atmosphere?
Ozone is formed when heat and sunlight cause chemical reactions between oxides of nitrogen (NO X ) and Volatile Organic Compounds (VOC) , which are also known as Hydrocarbons. This reaction can occur both near the ground and high in the atmosphere.
Is ozone a greenhouse gas?
Ozone is technically a greenhouse gas , but ozone is helpful or harmful depending on where it is found in the earth’s atmosphere. ... The protective benefit of stratospheric ozone outweighs its contribution to the greenhouse effect and to global warming.
What is ozone depletion class 10th?
Ozone layer depletion means the thinning of the ozone layer present in the upper atmosphere . That is harmful to nature and the atmosphere. Ozone layer depletion is one of the major problems for the atmosphere and also for all the living beings including the flora and fauna of this earth.
