It is called a plateau.
a mountain
A plateau is a flat elevated landform that is higher than the surrounding area. It is characterized by a relatively flat top surface with steep sides or cliffs. Plateaus can be formed by geological processes such as erosion, volcanic activity, or tectonic movement.
An elevation is something which is higher than anything surrounding it. (tallness)

The difference in elevation of a landform from its lowest point to its highest point is called the relief. It is the vertical distance between the two points and is often used to describe the topography or ruggedness of the land. A higher relief indicates more variation in elevation.
The Rockies have higher elevations than the Appalachians. The highest peak in the Rockies, Mount Elbert, reaches over 14,000 feet, while the highest peak in the Appalachians, Mount Mitchell, reaches around 6,600 feet.
They are mountain ranges, or mountain chains, the Himalayan Mountain Range being one example.
A valley is a low-lying area of land between mountains or hills, often formed by the erosion of a river or glacier. A plateau, on the other hand, is a flat and elevated landform that rises sharply above the surrounding area. Plateaus are usually higher in elevation compared to valleys and can be bordered by steep cliffs or mountains.
A plateau is a flat-topped elevated landform, like a mountain that has been worn down over time. It is higher than the surrounding area and has a relatively flat surface on top.
