Which atmospheric layer is characterized as being wider at the equator than at the poles?

The troposphere is the atmospheric layer where most weather phenomena occur and is characterized by a depth that varies with latitude. It is indeed wider at the equator than at the poles due to the influence of temperature and the Earth's rotation. At the equator, the warmer temperatures cause the air to expand, leading to a thicker layer of troposphere. In contrast, at the poles, the colder temperatures result in a much thinner troposphere. This variation is essential for understanding weather patterns and climate dynamics across different regions of the Earth. The other atmospheric layers, such as the stratosphere, mesosphere, and thermosphere, don't exhibit the same significant differences in width based on latitude in the same way the troposphere does. Thus, the troposphere's behavior exemplifies how atmospheric processes are influenced by location and temperature.
