The atmosphere around the earth:
View all questions of this test
- The atmosphere consists of different layers with varying density and temperature.
- The column of the atmosphere is divided into five different layers depending upon the temperature condition.
- They are troposphere, stratosphere, mesosphere, thermosphere, and exosphere.
Key-Points
The troposphere
- It is the lowermost layer of the atmosphere.
- Its average height is 13 km and extends roughly to a height of 8 km near the poles and about 18 km at the equator.
- The thickness of the troposphere is greatest at the equator because heat is transported to great heights by strong convectional currents.
- This layer contains dust particles and water vapour.
- All changes in climate and weather take place in this layer.
- The temperature in this layer decreases at the rate of 1°C for every 165m of height.
- This is the most important layer for all biological activity.
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 ultra-violet radiation and shields life on the earth from an intense, harmful form of energy.
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.
- Meteors are burning up in the mesosphere. The meteors make it through the exosphere and thermosphere without much trouble because those layers don’t have much air. But when they hit the mesosphere, there are enough gases to cause friction and create heat.
- The upper limit of the mesosphere is known as the 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.
- 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 the outer space.
