The Athensphere is not a layer in the Earth. The asthenosphere is the region of the mantle that is capable of moving by convection and has been linked to the movement of the tectonic plates (the lithosphere).
in the asthenosphere, which is in the lower part of the mantle, magma churns in a convection current which is like a cycle. Tectonic plates sit above this movement in the lithosphere. This is what causes continents to move little by little. Hot magma rises and at the lithosphere, it cools and falls because it is now denser. This is like a circular movement, or convection current.

The earth is made up of multiple tectonic plates. These plates are propelled by convection in the mantle layer below the crust (lithosphere)
The softer layer below the lithosphere is the asthenosphere. The asthenosphere begins at a depth of approximately 150 km. It has convection currents that arise from the heating and subsequent rising of material from the lower asthenosphere. These convection currents drive the movement of lithospheric plates at the surface, and are the cause of tectonic activity.

The plate tectonic theory states that new Earth crust is being formed while old crust descends back into the mantle. Uneven heating in the mantle causes convection which keeps the crust in motion. The constant movement of Earth's plates are the result of the three types of boundaries, divergent, convergent, and transform, and the convection in the mantle.
Subduction and sea floor spreading are both a result of the movement of the tectonic plates.Plate Tectonics
