15 points going to brainliest! scientists have discovered convection currents inside earth. explain how these convection currents move and what layer(s) they occur in.

These movements occur in the mantle which include the lithosphere, Asthenosphere, and the Mesosphere. These convection currents move from tectonic plates. These plates have heat generated from the radioactive decay of elements deep in the interior of the Earth creates magma

Seafloor spreading and other tectonic activity processes are the result of mantle convection. Mantle convection is the slow, churning motion of Earth's mantle. Convection currents carry heat from the lower mantle and core to the lithosphere. ... Seafloor spreading occurs at divergent plate boundaries.
