yes or no
Yes, convection of the Earth's atmosphere does occur in the mesosphere, but it is not as significant as in the lower atmosphere due to the thinner air. The mesosphere is characterized by very low densities and temperatures, which can limit the vertical movement of air compared to the lower levels of the atmosphere.
The upward movement of warm air is called convection, while the downward movement of cool air is called subsidence. This process occurs due to differences in temperature, density, and pressure in the atmosphere, leading to the circulation of air masses.
The mesosphere is the 3rd layer of Earth's atmosphere and can be the coldest part of Earth's atmosphere. The top part of the mesosphere can get up to -90 degrees celsius (-130 degrees Fahrenheit).
The upward movement of warm air is called convection. This process occurs as warm air rises due to its lower density compared to cooler air, creating vertical air currents in the atmosphere.
The air pressure in the mesosphere is low compared to the pressure at lower altitudes. This is because the mesosphere is located at an altitude where the density of the atmosphere is much lower, resulting in lower air pressure.
The air temperature in the mesosphere layer decreases with increasing altitude. This is because the mesosphere is the coldest layer of the Earth's atmosphere, with temperatures decreasing to as low as -90 degrees Celsius at the top of the layer. The decrease in temperature is primarily caused by the decreasing density of gas molecules at higher altitudes in the mesosphere.
Convection occurs in the lower atmosphere as warm air rises and cold air sinks, creating vertical air movement. Conduction primarily occurs at the Earth's surface where heat is transferred from the ground to the air directly in contact with it.

Heat in the mesosphere is primarily transferred through a process called adiabatic cooling, which occurs as the air rises and expands due to lower pressure at higher altitudes. Additionally, heat can also be transferred through a small amount of direct radiation from the sun during the day and infrared radiation from the Earth's surface.

The mesosphere, which lies between the stratosphere and the thermosphere, experiences a decrease in temperature with increasing altitude. This is primarily due to the diminishing density of air and the limited absorption of solar radiation at these heights. Unlike the stratosphere, where ozone absorbs UV radiation and warms the air, the mesosphere lacks significant heat sources, resulting in cooler temperatures. Therefore, temperature in the mesosphere is generally constant and decreases with altitude, reaching its coldest point at the mesopause.
