Due to computational constraints, the deformation of a subducting plate cannot be accurately resolved in mantle‐scale convection models, so its effect on convection is difficult to investigate. We ...

Three-dimensional disturbances exist on all scales from the molecular to those of the boundary conditions. In studies of mantle convection and other fluid problems in the Earth Sciences, the role of ...

but could never really be reconciled with the concept of mantle convection." "This model explains the observations in a simple way and permits a myriad of new hypotheses for global geochemical ...

In the Earth's mantle convection is the dominant mechanism of heat transport ... temperature gradient in excess of the adiabat (see below for definition), because stronger thermal gradients lead to ...

Geodynamics refers to the processes by which mantle convection shapes and reshapes the Earth and other rocky planets. Its study includes plate tectonics, volcanism, the chemistry of lava and ...

A convection current is the movement of a fluid ( such as air or water ) caused by differences in temperature. When part of a liquid or gas is heated, it expands and becomes less dense. The warmer, ...

Waves in the underlying layer known as the mantle can scour off the keels of continents, buoying their surfaces upward to form prominent landforms far from any active plate boundaries, researchers ...

affecting the type and amount of volatiles emitted during magmatic activities sourced from the mantle. This, in turn, regulates the composition of the atmosphere. The parameter researchers proposed is ...
