How can the convection rolls be derived and mapped? First, we can assume that hight and width is the same, second that horizontal radius is in harmony with Earth’s radius. This has been calculated, and drawn accurately. The result is a model, very useful for geologists and geoscience in general, something we should know about!
As the layers of Earth are drawn to scale, it is obvious that this convection rolls pattern fits perfectly into the layers. By deriving the system to the north and south, countless geological features can be explained thoroughly, hitherto not understood.
