Stratosphere is one of the five layers of the earth’s atmosphere. The other layers include the mesosphere, thermosphere and the exosphere. It is the second layer and you will find this below the mesosphere and above the troposphere. The depth of the stratosphere like that of the troposphere depends on the latitude.

This can have a depth of as much as 5.5 miles or it can also be as deep as 20 miles. This is also the layer that is closer to the earth. It is also much warmer as it is near the mesosphere. The stratosphere also contains a lot of ozone. It also contains a type of oxygen molecule that will help in absorbing the ultraviolet rays of the sun. This they use in order to heat this atmosphere layer.

Know About Some Important Facts Of The Stratosphere

  • The atmosphere consists of a total of four layers and this stratosphere is one of those four spheres. The other layers of the atmosphere are the biosphere, lithosphere and also the hydrosphere.
  • The word “stratosphere” is derived from the word “Strato” that means layer. Layer means the shape of the earth.
  • About 24% of the total atmosphere of the earth consists of a stratosphere.
  • The stratosphere consists of as much as 19% of the total amount of gases that is present in the earth.
  • Again as much as 90% of the ozone gas is present in the upper crust of the stratosphere. This is the ozone gas that you will actually require for the survival of human beings. It absorbs the sun’s UB radiation that might otherwise prove to be dangerous.

Some More Details That You Will Need To Know

For a number of years, the scientists have been warning you about the damage that you are causing to the layer of this ozone gas. In order to create more of the ozone gas and in order to replenish the loss, you will have to plant in a number of trees. Ozone gas is damaged when the dust and the other volcanic gases reach this part of the earth’s atmosphere. Ozone gas is very important for the people on earth. This is because it is this gas that will help you to decide the number of ultraviolet rays that will be able to reach the earth. This UV radiation helps in the production of Vitamin D in the body. If, on the other hand, you get too much of it then it might destroy the tissues that are there in the body.

The amount of water vapor that is there is the atmosphere is extremely low. As a result of this, you will not be able to find any clouds in the stratosphere. The airplanes try to fly in this stratosphere because this way they will be experiencing a lesser amount of turbulence. There are also certain bird species that are able to fly in this stratosphere.
