Definitions:

Ocean-Continent Convergence

A type of plate boundary where a continental plate and oceanic plate collide, often resulting in volcanic activity and mountain building.

Fold and Thrust Belt

A series of mountainous folds and thrust faults created by the compression of the earth's crust.

Foreland Basin

A structural basin that forms adjacent to mountain ranges, resulting from the earth's crust flexing downward due to the weight of overlying mountains.

Normal Faults

Faults where the hanging wall moves downward relative to the footwall, typically caused by extensional forces.
