    Atmosphere

Hello everyone! We all know that we all breathe in Oxygen. So, where will the oxygen and the other gases be present in the air? Yes, it is present in the Atmosphere. Today, we all will learn more about the atmosphere.

Atmosphere:

• The atmosphere of the Earth is a layer of gases.
• The gases present in the Atmosphere are:

      1. Nitrogen - 78%

      2. Oxygen - 21%

      3. Carbon dioxide - 0.3 %

      4.Othere gases -  0.4%

• There are many layers present in the atmosphere
• The different layers present in the Atmosphere are:

          1. Troposphere

          2. Stratosphere

          3. Mesosphere

          4. Thermosphere

          5. Exosphere

Troposhere:

• The Troposhere has an average height about 13 kilometer.
• All the weather phenomena will happen in this layer. Example - rainfall, fog, and etc.
• The air we breathe (Oxygen) is present in this layer

Stratosphere:

• The Stratosphere has an average height about 50 kilometer
• The Stratosphere is free from clouds.
• The Stratosphere contains the Ozone layer.
• The ozone layer will protect us from the UV rays.

Mesosphere:

•  The Mesosphere has an average height about 80 kilometer
• The meteriods will burn up in this layer

Thermosphere:

• The Thermosphere has an average height about 80 - 400 kilometer.
•  In the thermosphere, the radio waves will be reflected back to earth
• The thermosphere is other wise known as "Ionosphere", because of the ions present.

Exosphere:

• The exosphere will have an average height about 166 kilometer and more
• The exosphere is the outer most layer in the atmosphere
• The exosphere will lead to outer space
• The air in the exosphere is very thick.

Thank you!
