The difference between a "face" and a "flat surface" is found in what is being described by each term. A "face" refers either to the direction of a surface or to the simple fact of a surface as a surface. By contrast, a "flat surface" refers to the quality of the surface in question. Thus, one "face" of a building may be flat, smooth, curved, etc., while another may be similar or different.
a map is flat an atlas has different types of maps and a globe is round
Plateaus are typically flat elevated landforms with a relatively level surface area. However, some plateaus may have a slightly sloping surface.
A flat representation of the Earth is called a map projection. The surface of the Earth cannot be accurately represented on a flat surface, so there are various way to approximate it. The different way are called projections.
A flat-topped mountain is called a plateau. Plateaus are elevated landforms with a relatively flat top surface that are often formed by the erosion of surrounding land.
A mesa is a flat-topped hill with steep sides, while a mountain is a natural elevation of the earth's surface with a higher peak and generally larger size. Mesas are typically smaller and have a more defined flat summit compared to mountains.
