What is a Plateau? A plateau is classified as a section of land raised higher than its surrounding area of land. Plateaus form over millions of years. The formation begins when segments of the Earth’s crust smash into each other. Overtime the magma melts and rises towards the surface. After reaching above the surface, it hardens and solidifies forming a plateau.
