What is ozone molecule?
What is ozone molecule?
Ozone is an unusual type of oxygen molecule. Ozone (O3) has three oxygen atoms in each molecule, while normal oxygen (O2) has just two atoms per molecule. In the colored models, oxygen is traditionally shown as red.
How is ozone formed and destroyed?
As sunlight penetrates into the stratosphere, high-energy UV photons react with oxygen gas molecules, splitting them into individual oxygen atoms. The energy also causes the ozone to decomposed, producing an oxygen molecule and an oxygen free radical. …
Why do ground level ozone levels vary throughout the day?
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.
How dangerous is ground level ozone?
Breathing ground-level ozone can trigger a variety of health problems including chest pain, coughing, throat irritation, and congestion. It can worsen bronchitis, emphysema, and asthma. Ozone also can reduce lung function and inflame the lining of the lungs. Repeated exposure may permanently scar lung tissue.
Where are 10% of the ozone molecules located?
Each ozone molecule contains three atoms of oxygen and is denoted chemically as O3. Ozone is found primarily in two regions of the atmosphere. 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)).
Where is the hottest layer of the earth?
inner core
Why is exosphere so hot?
The particles in the exosphere are moving very quickly, so the temperature there is quite hot. Since the “air” is so thin in the exosphere – it is almost a vacuum – there are very, very few particles. We feel warmth when particles hit our skin and transfer heat energy to us.
What is a fact about the exosphere?
The exosphere is the highest and top layer of the Earth’s atmosphere. It marks the edge of space. There are very few molecules in this layer. The lightest atmospheric gases such as hydrogen and helium exist throughout the exosphere.
