upthrust
Pushing from below
Upthrust is a forceful upward movement or push.
In geology, it describes rock formations forced upward by tectonic pressure: The mountain range formed through volcanic upthrust.
In physics, particularly British usage, upthrust is the buoyant force exerted on an object submerged in fluid.
The verb means to thrust upward: Fists upthrust in victory.
