A layer of atoms near the surface of the earth in which living organism live is called troposphere. In this layer, 95% of air is found. The thickness of troposphere varies from 0-16 km. The upper boundary of the troposphere is called tropopause.


Stratosphere is extended to 16-50 km. The atmosphere of the stratosphere is called Ozonosphere and in the stratosphererain does not occur. The temperature increases in thestratosphere due to absorption of ultra-violet rays.


Mesosphere starts from the Stratopause layer. The level of the thickness of mesosphere varies from 50-80 km. Menopause is the uppermost layer of the mesosphere. Its temperature varies from -2Ëš to -100Ëš C. The temperature decrease in mesosphere due to thin gas layer and the absence of ozone gas


In thermosphere, radio waves are reflected and it is extended from 80-720 km. The temperature of thermosphere varies from -96Ëš to 1200ËšC. Thermosphere is also called ionosphere. It is called ionosphere because ionization process occurs in ionosphere.


The other name of exosphere is Fringe Region. The level of thickness of exosphere varies above 720 km and its temperature is 1200Ëš to 6000Ëš C. The exosphere is also known as helium zone. It is also known as helium zone due to abundance of helium.

Things to remember
  • Different types of layers of atmosphere are :
  • -Troposphere
  • -Stratosphere
  • -Mesosphere
  • -Thermosphere
  • -Exosphere
  • It includes every relationship which established among the people.
  • There can be more than one community in a society. Community smaller than society.
  • It is a network of social relationships which cannot see or touched.
  • common interests and common objectives are not necessary for society.
