  The layers of atmosphere are as follows:<div>1.Troposphere :</div><div>It is the lowest layer which starts from ground level and extends up to 10 km. We humans live in this layer. Most of the clouds appear here because 99% of the water vapor in the atmosphere is found in this layer .</div><div>2.Stratosphere :</div><div>The next layer up is called the stratosphere. The stratosphere extends from the top of the troposphere to about 50 km above the ground. The ozone layer is also found within the stratosphere absorb high-energy ultraviolet (UV) light from the Sun.</div><div>3.Mesosphere :</div><div>Above the stratosphere is the mesosphere. It is extended upto a height of about 85 km (53 miles) above our planet. Most meteors burn up in the mesosphere.</div><div>4.Thermosphere : </div><div>The layer above the mesosphere is called the thermosphere. Air is very rarely found here. High-energy X-rays and UV radiation from the Sun are absorbed in the thermosphere.</div><div>5.Exosphere :</div><div>It is considered as an outermost layer of atmosphere. They are very loosely bound to the atmosphere.</div>

  Earths atmosphere is made up of different layers.
  1. Troposphere: It is the lowest layer of the atmosphere. It is 8-15 km above the ground. This layer contains the oxygen that we breathe.
  2. Stratosphere: It lies above the troposphere which goes up to 50 km. This the important layer because it contains OZONE LAYER. ozone layer protects us from UV rays.
  3. Mesosphere: It extends up to 85 km. It is known for its low temperatures, where it gets colder with increasing the altitude.
  4. Thermosphere: It extends up to 600 km. This layer absorbs high radiation from the sun thereby the temperature increases.
  5. Exosphere: This the outermost layer. It starts around 600 km above the earths surface. It mainly consists of Hydrogen and Helium gases.
