What is the high flat land form where most of major cities reside?

The high flat land form where most of major cities reside is called a plateau. Plateaus are elevated areas of land that are relatively flat and are often located at high altitudes. Plateaus are often formed by tectonic uplift or by the erosion of mountains. They can be found in various parts of the world, and many major cities are located on plateaus. For example, the Tibetan Plateau in Asia is home to several major cities, including Lhasa and Xining. The Andean Plateau in South America is also home to several major cities, including Quito, Bogota, and La Paz.
