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… WebMar 13, 2024 · The core is the superheated center, the mantle is the thick, middle layer, and the crust is the top layer on which we live.

How does mantle convect

WebMantle convection is the result of heat transfer from the core to the base of the lower mantle. As with a pot of soup on a hot stove (Figure 3.12), the material near the heat source (the soup at the bottom of the pot) becomes hot and expands, making it less dense than the material above. Buoyancy causes it to rise, and cooler material flows in ...

WebThe mantle is generally considered to convect as a single layer (whole mantle convection) or, at most two (the standard geochemical model). However, the mantle is more likely to convect in multiple layers as a result of gravitational sorting during accretion and the density difference between the mantle products of differentiation. WebAnswer: Radioactive decay In the middle of the Earth releases heat that heats the core. This heat moves up to the surface. On the way it heats the material below the crust. The warmest part of this mantle is closer to the core than the mantle at the surface so the hotter mantle rises up towards t...
