what is convection cells in geology
See also: Convection. In the field of fluid dynamics, a convection cell is the phenomenon that occurs when density differences exist within a body of liquid or gas.These density differences result in rising and/or falling currents, which are the key characteristics of a convection cell.ee also: Convection. In the field of fluid dynamics, a convection cell is the phenomenon that occurs when density differences exist within a body of liquid or gas.
This is the cell, a current develops as hot liquid rises and cooler liquid sinks. All liquids do this weather air, water, or molten rock. In a pot, the liquid is water, the heat source is the stove burner. In the earth the mantle is the liquid, the heat source is the core.Cells develop in different areas due to variations in the mantle.here cool material is sinking between two cells you have a subduction margin form, the asthenosphere is dragged down and with it the plate forming subduction zones. In the odd occasion you might have a hot spot. I describe this as somethng like a welding torch burning through a plate of steel.
