What are the differences between troposphere and stratosphere

Tropopause: The upper layer of troposphere is called tropopause. It is a thin layer and its height changes according to latitudes.

Stratosphere: The stratosphere is the second major layer of Earth's atmosphere, just above the troposphere, and below the mesosphere.

The differences between the stratosphere and the troposphere include:

1.) The troposphere is the lowest level of the atmosphere, so it is in contact with the Earth’s surface. In contrast, the stratosphere is located above the troposphere, so it is not in contact with the Earth’s surface.

2.) The air density and air pressure are much lower in the stratosphere. In fact, stratospheric air is too thin for people to be able to survive without pressurized air to breathe.

3.) On average, the troposphere is warmer than the stratosphere.

4.) Meteorological weather primarily occurs in the troposphere and does not occur in the stratosphere.

5.) Concentration of stratospheric water vapor, i.e., humidity, is always very low; in contrast, tropospheric humidity can vary quite a bit from the very high humidities in the tropics and extremely low humidities in the polar regions.

6.) Ozone layer only occurs in the stratosphere. Also, smog and surface level pollution only occur in the troposphere.
