surface

The surface is the outside of anything. The earth, a basketball, and even your body have a surface.

A surface is the top layer of something. The surface of the moon is rocky, with a lot of craters, while the surface of the earth has a lot of water. Sandpaper has a rough surface; a balloon has a smooth but rubbery surface. When we use the word surface, it usually means there is a lot of stuff underneath. That applies to our use of surface to mean outward mood, as in "You look happy on the surface, but I know you're angry on the inside."
