What pattern of air density changes within layers layers of the atmosphere?

In the Earth's atmosphere, air density decreases with increasing altitude in the troposphere, where most weather occurs. This trend continues into the stratosphere, though the rate of decrease slows down. Above the stratosphere, in the mesosphere, air density continues to decline, while in the thermosphere, it decreases dramatically, despite temperatures rising. Overall, the pattern shows a consistent decline in air density with altitude, influenced by factors like temperature and pressure.
