'Surface' refers to the outermost layer of something or the top layer of a particular object, material, or area. It can be smooth or rough and it can be visible or hidden. For example, the surface of a table is the top layer that is visible when you look at it. You can use the word 'surface' when talking about things like water, floors, walls, and roads. It can also be used when describing the appearance or texture of something. For instance, you can say "the surface of the cake was smooth" or "the surface of the lake was calm." So, whenever you want to talk or write about the top layer or outermost part of something, use the word 'surface.'
