Why should one study the layer-cake model at all? Certainly, stratigraphic traps can occur in flat-lying strata, which fit the layer-cake model. In addition, many great oil fields are found in huge, gently sloping anticlines, where the layer-cake approximation serves quite well. However, exploration cannot be restricted to the use of such a simple model. It is essential that geophysicists have the tools to model regions of highly complex geologic structure. Reflections come from interfaces, and the observed reflections are used to reveal structure.
