Why is the ozone formed over the equator?
Free atoms can recombine to form into molecules, but if a free oxygen atom collides with a molecule (O2), it forms O3. Ozone is repeatedly created and destroyed in the atmosphere by the UV rays coming from the sun. Most of which is formed where solar radiation is the greatest (the equatorial belt).
Is there more ozone near the equator?
“A ton of emissions in a region close to the equator, where there is a lot of sunlight and intense heat, produces more ozone than a ton of emissions in a region farther from it.” (In the upper atmosphere, or stratosphere, ozone helps protect against the sun’s ultraviolet rays.)
Where is most ozone formed?
tropical stratosphere
As a result, the largest ozone produc- tion occurs in the tropical stratosphere. The production of stratospheric ozone is balanced by its destruction in chemical reactions. Ozone reacts continu- ally with sunlight and a wide variety of natural and human- produced chemicals in the stratosphere.
What causes the formation of ozone?
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.
Why is ozone important to life on Earth?
The ozone layer acts as a shield for life on Earth. Ozone is good at trapping a type of radiation called ultraviolet radiation, or UV light, which can penetrate organisms’ protective layers, like skin, damaging DNA molecules in plants and animals.
Why is ozone seasonal?
Compounds found in vehicle and industrial air pollution, when exposed to sunlight and hot temperatures, can react to form ozone. The combination of more direct sunlight and longer daylight hours creates the summer ozone season.
How is ozone formed in the upper atmosphere?
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 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. For example, nitrogen oxides are released from the burning of vegetation during a fire.
What is ozone formation?
Ozone is a molecule made up of three oxygen atoms, often referenced as O3. Ozone is formed when heat and sunlight cause chemical reactions between oxides of nitrogen (NOX ) and Volatile Organic Compounds (VOC), which are also known as Hydrocarbons.
How is ozone formed in the upper part of the atmosphere of the earth?
Why is stratospheric ozone formed over the equator?
Stratospheric ozone is naturally formed over the equator because it is where the large amount of solar radiation strikes the Earth. The sunlight breaks apart the oxygen particles in the atmosphere which then forms into Ozone. Aside from the formation of ozone in the equatorial belt,…
How is sunlight related to the formation of ozone?
The connection of sunlight and ozone formation is that sunlight provides energy to break the bonds of oxygen molecules and thus it helps in formation of ozone.
Where is the greatest concentration of ozone in the atmosphere?
Although ozone is present in the Earth’s entire atmosphere, there is a greater concentration of it located at the latitudes between 19 to 30 km above the Earth’s surface and is called the ‘ozone layer,.
Is the ozone in the troposphere harmful to humans?
However, ozone also exists in small amounts in the region called the troposphere. Ã’šÃ‚ This ground level ozone is very harmful to us humans because it is basically the byproduct of urban smog or human activities like the gas emitted from cars.
