Explanation:
The differences between the stratosphere and the troposphere include:
- 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.
- Humans live in the troposphere, not the stratosphere. People only spend time in the stratosphere is when they are traveling through it on an airplane, or flying through it while riding in a rocket.
- 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.
- On average, the troposphere is warmer than the stratosphere.
- Meteorological weather primarily occurs in the troposphere and does not occur in the stratosphere. For example, it only rains and snows in the troposphere. Also, virtually all clouds are located in the troposphere.(The only exception are polar stratospheric clouds which only occur in the winter near the Earth’s poles).
- There are differences between tropospheric and stratospheric chemistry. For example, the ozone layer only occurs in the stratosphere. Also, smog and surface level pollution only occur in the troposphere. Additionally, the 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.
The similarities between the stratosphere and the troposphere include:
- The most abundant gases in both the stratosphere and troposphere are molecular oxygen and nitrogen.
- Both the stratosphere and troposphere blanket the whole Earth.
- Both the stratosphere and troposphere warm up during the day and cool down at night.
Both the stratosphere and troposphere are transparent at visible wavelengths. The proof is that on a clear night neither the troposphere nor the stratosphere obstruct our view of the stars, and on a clear day they don’t block our view of the sun.
