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] ...
How do plates move where convection currents are rising? Where does the heat that drives mantle convection come from? Who discovered convection currents? What is the pressure of the Earth's mantle? How do scientists know there is convection in the mantle?
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 ...

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 ...

What causes convection currents in the mantle?Earth's LayersThe Earth is not just one big, solid ball. Rather, it is made up of several distinct layers. At the center is the inner core; surrounding this is the outer core. The thickest layer is the mantle, and the outermost layer is ...

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 ...
