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 … Web16 de jul. de 2024 · The basaltic magma reservoir in turn provides heat for a lower-temperature rhyolite magma reservoir at depths of 4–14 km (2.5–8.5 mi), but that is only about 5–15% molten.
