Most of the models have certain approximation those are necessary for describing a model. As the observations are not exact so there may be little difference between what we observe. Models which are simple increase the accuracy and becomes superior in nature as well.
There are certain limitation of model such as , most of the model cannot explain the complex natural phenomena. For example when we want to measure distance it becomes difficult ,in the model we can represent earth as a sphere but it is difficult to show variation in distance as there are valleys mountain ranges and other features.
