- Thermosphere - Fourth layer of Earth's atmosphere.
- Aurora Borealis - Ionosphere layer of thermosphere.
- Large-scale air turbulence and mixing at this layer - Troposphere
- Stratosphere - Second lowest layer of Earth's atmosphere. No Air turbulence so airplanes fly in this layer.
- The coldest temperatures in the atmosphere occur at the junction- of Stratosphere and mesosphere
- Maximum ozone - Ozone layer in Stratosphere
Explanation:
Atmosphere is formed by mixing of gases. The layers of atmosphere is given below.
1. Troposphere - 
- The first layer of the atmosphere.
- Weather occurs in this layer.
2.Stratosphere - 
- The second layer of Earth's atmosphere. 
- Contains Ozone layer.
3. Mesosphere - 
- The third layer above the stratosphere. 
- Coldest layer.
4. Thermosphere - 
- The fourth layer of the atmosphere. 
- Warmest layer.
- Ionosphere - lowest level of thermosphere above mesosphere. 
- Aurora Borealis, Northern and Southern lights are seen in this layer.
- Exosphere - outermost layer of thermosphere.
- Satellites are in this layer.
- Outer space with no gravity.
