... Plate tectonic theory states that the Earth's surface is broken into rigid lithospheric plates that slide on top of asthenospheric mantle. The boundary between these lithosphere and asthenosphere is based on rheology (typically defined by an isotherm ~1280°C- it is not a compositional boundary). ...
