The Ozone Layer:

  • A coating made if natural gas, Ozone, is found within one of Earth's layers, the Stratosphere.

  • This layer is really important to human beings since it protects humans as well as living things on Earth from the harmful radiation of the sun, the ultraviolet radiation.

3

The Importance of the layer:

  • It absorbs almost 98% of this radiation and allows only a little amount of the UV radiation to reach into Earth's atmosphere.

  • without it the radiation would reach the Earth's surface and thus cause severe damage to life on our planet.

  • Over 90% of the Earth's ozone is found in the ozone layer.

Characteristics features of Ozone:

  • It is a slightly colored light blue gas which is a little soluble in water.

  • At 112C, ozone turns into a dark blue liquid.

  • If it were heated at 193C, it turns into a violet-black liquid which smells like burning electrical wires.

  • Scientists discovered that the ozone layer is in danger and is in depletion (being reduced) because of many chemicals like Chlorofluorocarbons or CFC used by human beings.

5

Chemicals affecting the ozone:

  • Deodorant sprays.

  • Refrigeration gases.

  • Air-conditioning.

  • The over use of such utilities which contains harmful chemicals affects the ozone layer.

6

The ozone at risk:

  • It was discovered a few years back that there is a hole in the ozone layer.

  • It is located over the Antractic.

  • The more we use such chemicals the bigger is the hole in the ozone gets.

  • The hole of the ozone means that the UV radiation of the sun is reaching Earth's surface in bigger amounts thus putting all living things on Earth in danger.

7

Ways of protection:

  • It is always better to wear sunscreen lotions while spending a day at the beach to protect our skin from being harmed when exposed to the sun.
