Where do earth's convection currents occur?

Best Answers

Convection currents occur in the Earth's mantle - the semi-solid, molten material between the crust and the core. The heat generated from the core and through radioactive decay makes the mantle material less dense thus causing it to rise. read more

Convection currents in the magma drive plate tectonics. Heat generates from the radioactive decay of elements deep in the interior of the Earth creates magma ( molten rock)in the aesthenosphere. read more

Large convection currents transfer heat to the surface of the Earth, and these currents cause the magma to break apart. When this happens, it creates divergent plate boundaries. When the plates separate, they cool down and get reabsorbed back into the aesthenosphere. read more
