How does a global convection cell work?

Answer 1

With all the heat under the crust into the mantle, the hot magma starts to move like any convection current so it goes up and then back around again to be reheated. at the top the convection current is so strong it pulls the plates apart and magma seeps up through and becomes lava.

Answer 2

warm air from ground rises and becomes less dense, goes higher then becomes colder since all the way up there theres no heat source and finally it becomes less dense and falls. this happens in a shape of dual bike tire like patterns. this repeats in a cycle.

Answer 3

Global convection cells are large-scale atmospheric circulation patterns driven by temperature differences between the equator and poles. Warm air rises at the equator, moves towards the poles at high altitudes, cools, and then sinks back towards the surface at around 30 degrees latitude. This creates three cells in each hemisphere: Hadley, Ferrel, and Polar cells, which collectively distribute heat and moisture around the Earth.

Answer 4

when the it goes up it get less dense and when it goes down it still get less dense and it start all over

Answer 5

Convection is simply a heat transfer - for example the act of boiling water, heat is transferred from the cooker to the water container, thus heating the water
