The wide flat raised surface in the interior of a landform is commonly referred to as a "plateau." Plateaus are characterized by their elevated terrain, which is often surrounded by steep cliffs or slopes. They can form through various geological processes, including volcanic activity, erosion, or uplift of the Earth's crust.
a surface that does not move
A 2D interior will be length times width (a flat shape) as in the area of a floor.A 3D figure would be length times width times depth (a raised shape) as in a box.The units used would depend. A floor would be in feet and inches or metres and centimetres.A 3D figure would be in a similar measurement, but given in cubic units.

A mirror with a flat surface - planar
Its base is a flat surface

A raised panel door has a rim, then an indentation and the panel inside it is raised to the level of the rim. A flat panel door is more like a picture frame where the rim is raised and the panel inside it is indented.
That sounds like a ramp to me.

The name given to flat areas between bumps and hollows on Earth's surface is "plateau". Plateaus are elevated flat-topped areas that are higher than the surrounding terrain.
Maria, also known as lunar seas, are the dark relatively flat regions of the moon's surface that were formed when interior lava filled large basins.

A ramp is a flat surface that is elevated at one end, used to move objects from a lower level to a higher one, allowing for easy movement or transportation.
Slip-On Flat Face Flange. It means the face of the flange, the surface the physically touches the next flange is flat as opposed to raised (SORF Flange)
I think you mean a plateau. Plateau: expanse of raised land with a level surface. Also known as tableland, do to the flat tops.
A plateau is a large, flat area commonly found in the interior of continents. Plateaus are typically elevated landforms with a relatively flat, level surface that rise above the surrounding terrain. They are formed by geological processes such as faulting, volcanic activity, or erosion.
