Which is part of the convection cycle in earth's atmosphere

It occurs in in fluids that moves freely such as water and air. In the atmosphere, convection is the rising and falling of air masses. In convection, the hot, less dense air at the equator rises and cool, dense air at the poles falls and moves toward the equator

Atmospheric circulation and weather patterns around the globe.

Explanation:

Convection can be described as the transfer of heat from bulky molecules. Convection cannot take place in solids as the most suitable medium is the gases. It can be natural, forced, gravitational and thermomagnetic also due to the combustion and capillary action. Convection is generally seen as rising air currents in the atmosphere, the concept of convection cells known as Bernard cells, occurring due to the result of an exchange of heat with the cooler climates as arm air is less dense and hence is overridden by the cooler and denser air mass from below. Latitudinal radiation occurs due to the heat changes in per unit area which is highest at the equator and is known for the production of Hadley cells that are due to the release of the strong convective motion coming from the latent heat and water vapor from this doldrum area. Pressure belts like Hadley, Ferrel and polar cells and their associate impacts on the convective cycle produce.
