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.
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.
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.
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.

In the mesosphere, the air is more dense.
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.
Fiberglass insulation primarily works through conduction, where heat transfer occurs through direct contact. It reduces heat transfer by trapping air within its fibers, slowing down the movement of heat. While it can resist some air movement (which is related to convection), its primary mechanism is conduction.
Changes in air movement, air pressure, and humidity are primarily influenced by temperature differences in the atmosphere. As warm air rises, it creates areas of low pressure which then leads to the movement of air to balance out the pressure. This movement of air also influences humidity levels as air masses with different temperatures and moisture content interact.
