Lithospheric convection currents
WebWhen a divergent boundary occurs beneath oceanic lithosphere, the rising convection current below lifts the lithosphere, producing a mid-ocean ridge. Extensional forces stretch the lithosphere and produce a deep fissure. When the fissure opens, pressure is reduced on the super-heated mantle material below. Web10 feb. 2024 · Convection Current Theory Convection Current Theory is the soul of the Seafloor Spreading Theory. Arthur Holmes in the 1930s discussed the possibility of convection currents in the mantle. These currents are generated due to radioactive elements causing thermal differences in the mantle.
