What properties are found in the mesosphere?

The correct choice highlights that the mesosphere possesses high pressure that offsets high temperature. In this region of the atmosphere, which is located above the stratosphere and below the thermosphere, the air pressure is significantly higher than in the more sparse regions above it, such as the thermosphere.

As altitude increases in the mesosphere, temperatures actually decrease, which contrasts with the behavior in the stratosphere where temperature increases due to the ozone layer absorbing solar radiation. The high pressure in the mesosphere is a result of the weight of the air above pressing down. This pressure plays a critical role in maintaining the stability of the atmospheric layers and influences the thermal characteristics of mesosphere, helping to regulate temperature and transition between different atmospheric conditions.

Understanding this balance of pressure and temperature is essential, as it helps to explain phenomena such as meteor trails which occur within this layer. The mesosphere also protects against meteoroids, which burn up upon entering the Earth's atmosphere due to the friction caused by the increasing density of air, further demonstrating the importance of the pressure conditions in this atmospheric layer.
