Definitions:

Thrust Faulting

A geological process where one rock layer is pushed up over another, often leading to mountain building.

Overriding Plate

The tectonic plate that sits above another plate at a convergent boundary, often responsible for mountain building and volcanic activity.

Ocean-Continent Convergent Boundary

A plate-tectonic boundary where an oceanic plate converges with a continental plate, generally expressed by subduction of the oceanic plate beneath the continent.

Flexing

The act of bending or tensing a material or muscle, often referring to the way earth's crust might bend under certain geological forces.
