What is the mantle ? Learn the mantle definition in earth science, facts about the mantle, and how the mantle is responsible for plate tectonics. Related to this Question What do mantle convection currents cause? What causes convection currents in the mantle?
A mantle plume is created through convection. A large amount of heat is transferred to the mantle from the core, making it more buoyant. Then the material rises to the bottom of the asthenosphere, as cold material sinks down in other areas of the mantle.What...

Slowconvection currentsdeep within the mantle generated by radioactive heating of the interior drive lateral movements of the plates (and the continents on top of them) at a rate of several centimetres per year. The plates interact along their ma...
The tabulated summaries of the predicted convection results (Tables 1–4) show, however, that the fits leave considerable room for improvement and this raises the fundamental question as to what aspects of the previous tomography models, or indeed the mantle flow calculations, may be deficient or...
The crust floats on a huge lake of lava called the mantle. The hot molten lava rises from the bottom to the top, where it cools down and moves back down. This movement creates a current called convection current, which drives the tectonic plates....
