Learn the definition of a convection current and discover where it occurs. Understand various convection current examples and find how they work with a diagram. Related to this Question What are some examples of convection currents? What are convection currents in the Earth's mantle?
How do Convection Currents Work? Convection Currents Diagram Lesson Summary FAQs Activities What are the examples of convection currents? Examples of convection currents can be observed in a pot of soup heating on the stovetop, the movement of molten material in the mantle of Earth, and the ...
aBecause I can swim 由于我可以游泳 [translate] aCurrents in Earth’s mantle called convection currents transfer heat in Earth’s interior. It is thought that this transfer of heat energy moves plates. 潮流在地球的披风叫的对流调动热在地球的内部。 它被认为热能这调动移动板材。 [translate] ...
Why do airplanes normally take off facing the wind? What sets surface currents in motion? Explain the terms convection and conduction? What will happen to the convection currents in the mantle if the Earth's interior eventually cools down?
A system of simple principles concerning the kinematics of the convection currents in the Earth's mantle was postulated as the starting point. The mantle is supposed to become more and more homogeneous downward. Here it is essential, for the reason of symmetry, that the current system has a ...

Scaling of the equations of conservation of mass momentum and energy with the characteristic values of the convective mantle indicates that in the vorticity equation, the advective terms are negligible but the horizontal temperature gradient term cannot be neglected because of the large Rayleigh number ...
With regard to the strain-stress relations valid in the mantle and the energy source of the convection the theory is without any presumptions. In compliance with recent hydrodynamic investigations the flow is introduced rather as roll currents than as a hexagonal cell pattern. From the feasible ...
