What is the highest level of the atmosphere, which includes the thermosphere, characterized by temperature inversions?

The highest level of the atmosphere is the exosphere, which is characterized by its extremely thin air and temperature inversions. In the exosphere, the atmosphere becomes so sparse that the individual gas molecules are far apart, and the temperature can increase with altitude due to the absorption of solar radiation. Unlike the layers below it, the exosphere has very few particles that are capable of thermal interaction, leading to a unique temperature profile. This layer is where satellites orbit and extends up to about 10,000 kilometers above the Earth.

The stratosphere, troposphere, and mesosphere have different characteristics. The stratosphere contains the ozone layer and is where temperature increases with altitude due to the absorption of ultraviolet radiation. The troposphere, where weather occurs, typically has a decrease in temperature with height. The mesosphere cools with altitude and is where most meteors burn up upon entering Earth's atmosphere. These other layers have distinct temperature behaviors that differentiate them from the exosphere.
