LANDFORM – a natural feature of a land surface

PLATEAU – flat, raised areas of land made up of nearly horizontal rocks that have been uplifted by forces within the earth

FOLDED MOUNTAIN – rock layers are folded like a rug that has been pushed up against a wall

VOLCANIC MOUNTAIN – mountains that form when molten material reaches the surface through a weak area in the Earth’s crust.
