It is the outer most layer of atmosphere. The air is very thin and there is no difinite outer limit. It is so hot because sunlight stikes the thermoshphere first. Nitrogen and oxygen molecules convert energy into heat. Thermoshphere doesn't contain enough air molecules to collide with. Lower layer of theromsphere is ionoshphere and the outer portion is exosphere.

FranThe stratosphere is characterized by its location above the troposphere, with temperatures increasing with altitude due to the presence of the ozone layer. It plays a crucial role in filtering out harmful ultraviolet radiation from the sun, and it is where most commercial airplanes fly.
Some characteristics are:
- The exosphere is the final layer of the atmosphere.
- It is not very well defined...it has no definite end. It just gradually fades into outer space.
- It contains the light gases, like Helium and Hydrogen.
- Pressure is too low to breath.
- Satilites are found here.
it is really hot and can be very cold too wrong
exosphere has satellites
Above the troposphere. Temperature increases with altitude
Contains a lot of ozone (ozone layer):
• Found in the stratosphere between 10 - 50km above the ground
• Protects us from the harmful effects of UV of certain wavelengths
• Decrease in ozone concentration -->Increase in UV-B radiation reaching the earth surface

What kind of light warms the stratosphere?
Ultraviolet light from the Sun warms the stratosphere by absorbing and heating up the ozone in this layer of the atmosphere. This absorption of UV light by ozone helps to create the temperature inversion characteristic of the stratosphere.
Is the upper stratosphere is cooler than the lower stratosphere?
Yes, the upper stratosphere is cooler than the lower stratosphere. This is because the absorption of ultraviolet radiation by ozone in the upper stratosphere creates a temperature inversion, where the temperature increases with altitude.
Is the upper stratosphere cooler than the lower stratosphere?
Is the upper stratosphere is cooler than the lower stratosphere?\
What layer of the atmosphere has two layer parts?
The stratosphere is the layer of the atmosphere that contains two distinct parts: the lower stratosphere and the upper stratosphere. The stratopause boundary separates these two regions, with the lower stratosphere characterized by a temperature inversion and the upper stratosphere containing the ozone layer.
Is the stratosphere in the homosphere or the heterosphere?
The stratosphere is part of the homosphere. The homosphere includes the layers of the atmosphere where the composition is relatively uniform, and the stratosphere is one of these layers characterized by the presence of the ozone layer.
