What are the layers of the atmosphere and why are they important?
They are the following from top to bottom (near the surface): Exosphere, Thermosphere, Mesosphere, Stratosphere and Troposphere. These five different layers provide protection and also make life possible because of the constituent gases which state the significance and importance of the atmosphere.
Why are layers of the atmosphere important?
The atmosphere protects life on earth by shielding it from incoming ultraviolet (UV) radiation, keeping the planet warm through insulation, and preventing extremes between day and night temperatures. The sun heats layers of the atmosphere causing it to convect driving air movement and weather patterns around the world.
Why are the layers of the atmosphere important?

What are the layers of the atmosphere and what do they do?
From lowest to highest, the major layers are the troposphere, stratosphere, mesosphere, thermosphere and exosphere. Troposphere. Earth's troposphere extends from Earth's surface to, on average, about 12 kilometers (7.5 miles) in height, with its height lower at Earth's poles and higher at the equator.Oct 2, 2019
What are the 7 layers of atmosphere and their characteristics?
Layers of the atmosphere
- The Troposphere. This is the lowest part of the atmosphere - the part we live in. ...
- The Stratosphere. This extends upwards from the tropopause to about 50 km. ...
- The Mesosphere. The region above the stratosphere is called the mesosphere. ...
- The Thermosphere and Ionosphere. ...
- The Exosphere. ...
- The Magnetosphere.
How are the 5 layers of the atmosphere held to the earth?
The atmosphere is the thin envelope of gas molecules surrounding the Earth; it is held down by Earth's gravitational pull. The atmosphere is concentrated at the Earth's surface and rapidly thins as you move upward, blending with space at about 100 miles above sea level.
What does the troposphere do?
This layer has the air we breathe and the clouds in the sky. The air is densest in this lowest layer. In fact, the troposphere contains three-quarters of the mass of the entire atmosphere.
What are the 4 most important of layers of the atmosphere?
The atmosphere is comprised of layers based on temperature. These layers are the troposphere, stratosphere, mesosphere and thermosphere. A further region at about 500 km above the Earth's surface is called the exosphere.
What are the 4 major layers of the atmosphere?

- Troposphere. ...
- Stratosphere. ...
- Mesosphere. ...
- Thermosphere. ...

Why are the four layers of the atmosphere important?
The atmosphere protects life on earth by shielding it from incoming ultraviolet (UV) radiation, keeping the planet warm through insulation, and preventing extremes between day and night temperatures. The sun heats layers of the atmosphere causing it to convect driving air movement and weather patterns around the world.
Which is the most important layers of the atmosphere?
Troposphere, why is it an important atmospheric layer?
- 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. ...
- The chemical composition determines the air quality.
