Yes, that's the basic cause of convection.
Cold, denser air falls
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.
Energy is transferred between the earths surface and the atmosphere via conduction, convection, and radiation. Conduction is the process by which heat energy is transmitted through contact with neighboring molecules.
In Earth's atmosphere and oceans, convection is primarily driven by temperature differences. When a fluid is heated, it expands and becomes less dense, causing it to rise. As it rises, cooler, denser fluid moves in to take its place, creating a convection current. In the atmosphere, differences in solar radiation and surface heating contribute to the temperature variations that drive convection.
Convection within Earth's atmosphere is primarily driven by the unequal heating of the Earth's surface by the sun. As air near the surface is heated, it becomes less dense and rises, creating an upward flow. As the heated air rises, it cools, becomes denser, and eventually sinks back towards the surface, completing the convection cycle that helps drive weather patterns.
convection currents distribute the warm air from the equator towards the north and south pole; they also make the earths crust move causing the earth's crustal features change.
