Because of the temperature difference between the Earth's surface and outer core and the ability of the crystalline rocks at high pressure and temperature to undergo slow, creeping, viscous-like deformation over millions of years, there is a convective material circulation in the mantle. Hot material upwells, while cooler (and heavier) material sinks downward. Downward motion of material occurs at convergent … WebConvection currents drive the movement of Earth’s rigid tectonic plates in the planet’s fluid molten mantle. In places where convection currents rise up towards the crust’s surface, … bowlero clear lake tx

WebJan 26, 2024 · As oceanic crust is subducting beneath another tectonic plate, it is sinking deep into the mantle. Subduction of these plates occurs at various angles, depending on how cool and dense the subducting slab is. In all cases, the sinking motion as one plate drags beneath the other creates a deep and linear "deep-ocean trench." The density of ...

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.
