How does the mantle convection theory work

WebConvection currents occur within: the geosphere – plate tectonics. the atmosphere - wind. the hydrosphere - ocean currents. Focus Question: What is the source of energy for convection currents in the geosphere? … WebHess suggested that mantle convection drives the crust apart at midocean ridges and downward at ocean trenches, forcing the continental migrations in their wake. Hess interpreted the oceanic crust as a hydration rind on serpentinized mantle; Dietz modified this to generate oceanic crust by submarine basalt eruptions.

Heat in the mantle comes from the Earth's molten outer core, decay of radioactive elements and, in the upper mantle, friction from descending tectonic plates. The heat in the outer core results from residual energy from the Earth's formative events and the energy generated by decaying radioactive elements. how to set up snowsql https://phillybassdent.com

WebIt's allowing the heat to be transferred from this one spot throughout the fluid. And so we call this process, this is convection. Now, the reason why we think the plates are moving is … Mantle convection is the very slow creeping motion of Earth's solid silicate mantle as convection currents carry heat from the interior to the planet's surface. The Earth's surface lithosphere rides atop the asthenosphere and the two form the components of the upper mantle. The lithosphere is divided into a number of tectonic plates that are continuously being created or consumed at plate boundaries. Accretion occurs as mantle is added to the grow…
