We investigate the physics of multi-scale convection in the Earth's mantle, character- ized by the coexistence of large-scale mantle circulation associated plate tectonics and small-scale sublithospheric convection. Several basic scaling laws are derived, using a series of 2-D numerical modeling and...

How is convection in the atmosphere similar to convection in the Earth's mantle? What is present in the mantle that can melt the crust that moves downward? Do convection currents occur in the inner core? Does the mantle undergo convection?
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] ...
A model for convection in the upper mantle of the Earth comprising two flows, one of percolating melt fluid (which need be no more than a small volume fraction in the intergranular channels of coherent solid matter), the other a solid plastic flow, avoids some paradoxical features of other ...
A coupled core-mantle evolution model that combines a global heat balance in the core with a fully dynamic thermo-chemical mantle convection model is developed to investigate the thermal evolution of the core over the 4.5 Gyr of Earth history. The heat balance in the core includes gravitational ...
We used a thermal model of an iron core to calculate magnetodynamo evo- lution in Earth-mass rocky planets to determine the sensitivity of dynamo lifetime andintensity to planets with different mantle tectonic regimes, surface temperatures, and core properties. The heat flow at the core-mantle ...
Comparing the similarity in the morphologies of the model plate margins to the Earth’s plate boundaries demonstrates that transform-like offsets are a result of stress induced weakness in the lithosphere owing to passive rupturing.Similar content being viewed by others Mantle flow in subduction ...
