How does gravity play a role in this action in a convection?

Answer 1

atmospheric circulation is the large-scale movement of air, and the means (together with the smaller ocean circulation) by which thermal energy is distributed on the surface of the Earth. The large-scale structure of the atmospheric circulation varies from year to year, but the basic climatological structure remains fairly constant.

Latitudinal circulation is the consequence of the fact that incident solar radiation per unit area is highest at the heat equator, and decreases as the latitude increases, reaching its minimum at the poles. It consists of two primary convection cells, theHadley cell and the polar vortex.

Longitudinal circulation, on the other hand, comes about because water has a higher specific heat capacity than land and thereby absorbs and re

Answer 2

In convection, gravity acts to generate buoyancy forces, which drive the movement of fluids. As a fluid is heated and becomes less dense, gravity pulls the denser, colder fluid down, creating a cyclical convection current. Gravity thus plays a key role in sustaining the movement and circulation of fluids in convection.
