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 … See more During the late 20th century, there was significant debate within the geophysics community as to whether convection is likely to be "layered" or "whole". Although elements of this debate still continue, results from See more A similar process of slow convection probably occurs (or occurred) in the interiors of other planets (e.g., Venus, Mars) and some satellites (e.g., Io, Europa, Enceladus See more On Earth, the Rayleigh number for convection within Earth's mantle is estimated to be of order 10 , which indicates vigorous … See more Due to the varying temperatures and pressures between the lower and upper mantle, a variety of creep processes can occur with dislocation creep dominating in the lower mantle … See more • Core–mantle boundary • Geodynamics – Study of dynamics of the Earth • Compatibility (geochemistry) - Distribution of trace elements in … See more WebMar 1, 2024 · The mantle is the mostly solid bulk of Earth’s interior.
