What is the 5th layer of the atmosphere?
There is a fifth layer called the exosphere, where the atmosphere gradually thins and merges with interplanetary space, but we won't consider this further as the molecules are so far apart, it no longer behaves like a gas.
What are the 6 parts of the atmosphere?
Earth's atmosphere has a layered structure. From the ground toward the sky, the layers are the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. Another layer, called the ionosphere, extends from the mesosphere to the exosphere. Beyond the exosphere is outer space.Nov 7, 2022
What part of the atmosphere do we live 7?
Therefore humans live in the lowest layer of the atmosphere called the troposphere.
Which is the most important layer of the atmosphere and why Class 7?
Importance of troposphere to life on earth
The study of the troposphere is very important because we breathe the air in this layer of air. The troposphere contains about 85% of the atmosphere's total mass.
Which layer of the atmosphere is most important for us and why Class 7?
Importance of troposphere to life on earth
The study of the troposphere is very important because we breathe the air in this layer of air. The troposphere contains about 85% of the atmosphere's total mass.
Why troposphere is the most important layer of the atmosphere Class 7?
Answer: Troposphere is the densest layer of atmosphere that is composed of water vapour, dust particles and many other impurities. Due to this thickness, troposphere absorbs most of the heat radiated by the Earth's surface, thereby, maintaining the temperature of the surface.
Which is the most important layer of the atmosphere answer?
Troposphere is considered as the most important layer of atmosphere. It is the lower most layer of the Atmosphere.
