The correct answer is Thermosphere.
Key Points
The atmosphere consists of different layers with varying densities and temperatures. The column of the atmosphere is divided into five different layers depending upon the temperature condition.
They are the troposphere, stratosphere, mesosphere, thermosphere, and exosphere.
The troposphere
They are the troposphere, stratosphere, mesosphere, thermosphere, and exosphere.
The troposphere
- It is the lowest part of the Earth's atmosphere in which all tropical changes take place. It contains about 75% of the total air in the atmosphere.
- This layer contains dust particles and water vapor.
- All changes in climate and weather take place in this layer.
- This is the most important layer for all biological activity.
- The zone separating the troposphere from the stratosphere is known as the tropopause.
- The temperature here is nearly constant, and hence, it is called tropopause.
The stratosphere
- It is found above the tropopause and extends up to a height of 50 km.
- One important feature of the stratosphere is that it contains the ozone layer.
- This layer absorbs ultraviolet radiation and shields life on the earth from an intense, harmful form of energy.
- The stratopause caps the top of the stratosphere.
The mesosphere
- It lies above the stratosphere, which extends up to a height of 80 km.
- In this layer, once again, the temperature starts decreasing with the increase in altitude and reaches up to minus 100°C at a height of 80 km.
- The upper limit of the mesosphere is known as mesopause.
The thermosphere
- It is located between 80 and 400 km above the mesopause.
- It contains electrically charged particles known as ions, and hence, it is also known as the ionosphere.
- Radio waves transmitted from the earth are reflected back to the earth by this layer.
- It contains Ions and helps in wireless communication
- The temperature here starts increasing with height.
The exosphere
- It is the uppermost layer of the atmosphere.
- This is the highest layer but very little is known about it.
- Whatever contents are there, these are extremely rarefied in this layer, and it gradually merges with outer space.
