WebBecause the radioactive source of heat is deep within the mantle, the fluid asthenosphere circulates as convection currents underneath the solid lithosphere. This heated layer is the source of lava we see in volcanos, the source of heat that drives hot springs and geysers, and the source of raw material which pushes up the mid-oceanic ridges ...

Convection currents rise and spread below divergent plate boundaries and converge and descend along convergent.
WebMay 17, 2024 · Where do convection currents take place is it in the lithosphere or the asthenosphere? Convection currents generated within the asthenosphere push magma upward through volcanic vents and spreading centres to create new crust. Convection currents also stress the lithosphere above, and the cracking that often results manifests … WebThree things needs for a convection current to occur differences in density, differences in temperature, gravity top of the asthenosphere just beneath the upper mantle where the …
