What are 5 facts about the ozone layer?

Top 10 facts about Ozone

  • Ozone was first discovered and isolated by the German-Swiss chemist Christian Friedrich Schönbein in 1839.
  • One molecule of ozone consists of three oxygen atoms.
  • Ozone near ground level may be harmful.
  • The Montreal Protocol to ban ozone-depleting chemicals such as CFCs was signed in 1989.

What are 3 facts about the ozone layer?

Facts About the Ozone Layer

  • The word “ozone” means smelly in Greek because the gas has a strong odor.
  • CFC molecules are highly stable and can last for up to 100 years.
  • One chlorine molecule from a CFC can destroy up to 100,000 ozone molecules.
  • Ultraviolet rays can also have bad effects on nature.

What are 2 facts about the ozone layer?

Ozone in the stratosphere absorbs most of the ultraviolet radiation from the Sun. Without ozone, the Sun’s intense UV radiation would sterilize the Earth’s surface. Ozone screens all of the most energetic, UV-c, radiation, and most of the UV-b radiation. Ozone only screens about half of the UV-a radiation.

Who invented ozone layer?

The Ozone Layer was discovered by the French physicists Charles Fabry and Henri Buisson in 1913. Why is Ozone Layer important? Ozone protects the Earth from harmful ultraviolet (UV) rays from the Sun.

What’s the ozone layer for kids?

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.

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 is ozone layer Class 10?

“The ozone layer is a region in the earth’s stratosphere that contains high concentrations of ozone and protects the earth from the harmful ultraviolet radiations of the sun.”

How thick is the ozone layer?

3 millimeters thick
Over the Earth’s surface, the ozone layer’s average thickness is about 300 Dobson Units or a layer that is 3 millimeters thick. Ozone in the atmosphere isn’t all packed into a single layer at a certain altitude above the Earth’s surface; it’s dispersed.

Where was the first ozone hole discovered?

Antarctica
A decline in spring ozone By 1984, the ozone layer over Halley Research Station in Antarctica was only about two-thirds as thick as it had been in earlier decades. At first Shanklin didn’t realise the enormous implications of the finding.

How is ozone layer 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.

Can the ozone layer break?

When chlorine and bromine atoms come into contact with ozone in the stratosphere, they destroy ozone molecules. One chlorine atom can destroy over 100,000 ozone molecules before it is removed from the stratosphere. Ozone can be destroyed more quickly than it is naturally created.
