Hello there!
Friction between lithosphere and asthenosphere is very weak, so the former can slide over the last one.
But due to this very lack of friction, nothing prevents the possibility for the whole plates to glide at high speed (to human time-scale!), causing immediate destruction of the Earth's surface and what it contains.
But as mountains have deep roots plunging into the asthenosphere,
could they work as anchors for the plate IN ALL THEIR EXTEND by making that hypothetic dangerous movement impossible?
