What is ozone layer easy definition?
The ozone layer is a thin part of the Earth’s atmosphere that absorbs almost all of the sun’s harmful ultraviolet light.
How do you explain the ozone layer to a child?
Ozone is a natural part of Earth’s upper atmosphere. This part of the atmosphere, about 15 miles (24 kilometers) above the surface, is called the ozone layer. It protects people by absorbing harmful rays from the sun. If they reach Earth, these rays can cause skin cancer, eye diseases, and other health problems.
Where is ozone layer?
the stratosphere
The Earth’s ozone layer. The ozone layer lies approximately 15-40 kilometers (10-25 miles) above the Earth’s surface, in the stratosphere.
What is the use of ozone layer?
The ozone layer is a natural layer of gas in the upper atmosphere that protects humans and other living things from harmful ultraviolet (UV) radiation from the sun.
What is ozone layer made of?
The ozone layer, also called the stratosphere, is composed of the ozone gas (90% of the total ozone in the atmosphere). The ozone has three oxygen atoms, and it is the result of the action of Ultra Violet (UV) radiation on oxygen molecules, composed of two oxygen atoms.
What causes ozone?
Stratospheric ozone is constantly produced by the action of the sun’s ultraviolet radiation on oxygen molecules (known as photochemical reactions). Polar stratospheric clouds create the conditions for drastic ozone destruction, providing a surface for chlorine to change into ozone-destroying form.
Can we make our own ozone?
Actually, it’s really easy to make ozone. Ozone is produced naturally when sunlight shines on air. It is produced by a chemical reaction in which several molecules of oxygen react with each other. But this reaction only takes place when there’s sunlight.
How is ozone formed?
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. This reaction can occur both near the ground and high in the atmosphere.
What is ozone layer long answer?
The ozone layer or ozone shield is a region of Earth’s stratosphere that absorbs most of the Sun’s ultraviolet radiation. It contains a high concentration of ozone (O3) in relation to other parts of the atmosphere, although still small in relation to other gases in the stratosphere.
How do you produce ozone?
In the first step, solar ultraviolet radiation (sunlight) breaks apart an oxygen molecule to form two separate oxygen atoms. In the second step, each atom then undergoes a binding collision with another oxygen molecule to form an ozone molecule.
What is harmful for ozone layer?
Chlorofluorocarbons or CFCs are the main cause of ozone layer depletion. These are released by solvents, spray aerosols, refrigerators, air-conditioners, etc. The molecules of chlorofluorocarbons in the stratosphere are broken down by the ultraviolet radiations and release chlorine atoms.
What happened ozone hole?
The ozone hole occurs during the Antarctic spring, from September to early December, as strong westerly winds start to circulate around the continent and create an atmospheric container. Within this polar vortex, over 50 percent of the lower stratospheric ozone is destroyed during the Antarctic spring.
