Describe the relationship between temperature , density, and movement of air in a convection cell

increase temp ... air expands ... less dense ... upthrust of colder air = more dense ... hot air rises, cold air takes its place ... convection ccirculation currents ... cells

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees.
